Celica Forums General Discussion Engine and Performance Three simple questions

Sorry for the long post, but these questions have been driving me crazy, and I really want to get these things ordered so I can get them in my GTS. I am not just coming out and asking these questions because I didn't want to search, I have been searching and these are the questions that still linger (sorry if i missed a thread that answered one of these)

1) Exhaust - I am leaning towards the TPR exhaust. Has anyone actually received their exhaust, installed it, and used it, and if so what do you think about it. What is the wait time, once ordered? Has it been dynoed on any other Celicas yet to see if that 10.5 hp gain is consistent, or if it is still just the best gains out there? I am looking for exhaust that is going to provide the best gains. I am also considering TRD, which I believe is second, behind TPR for performance gains.

2) CAI - I honestly know nothing about companies that make CAIs and thus won't pretend that I do. But I want to know who makes a good CAI, and is the TPR CAI worth considering, and in that case again what is the wait on the TPR CAI.

3) (last one) Short throw shifter - From what I have been able to find on this message board, I am under the impression, no matter how wrong it may be, that the B&M shifter provides the shortest throw. Also that it is a little stiff, but that wears away in a few weeks. And that the height of the shifter can be adjusted upon install. If this is wrong please tell me who else makes a good short throw shifter for the Celica.


Thanks for any help,

Alex

1. wait for tpr, or get trd but that is not as laoud
2. wait for tpr mainly becasue it doubles as SRI if it floods where you live.
3. B&M is the midrange one. TWM is shortest but hardest to use. Looks best becsaue it is so small. But for everyday use i woudl say B&M. you can get it fomr ebay for decent price.


Hopefully i was decently accurate

If you are good at shifting and want the best response get TWM. If your looking for something better than stock and not too hard to use get B&M.

^^^ what he sais for the rest

When you say to wait for TPR, do you mean to just order it and wait to get it, or wait a while to order it? Yeah it floods here, when it actually does rain, does a SRI just keep water from being indicted into the system? Also, how is the TWM hard to shift, it is just stiff, or are the gates easy to miss?

~Alex

no no by all means order the trp stuff, i jsut meant wait becasue sometimes it takes them alittle while to get the product out. Look in my profile for an SRI, you coudl still hydroluck (suck up water) but thats if its leik 2 feet high The TPR intake is a CAI in 2 sections. This allows you to take off the lower sectiona dn reattach the filter to it is now higher up, essentaully a SRI. Another plus of the TPR is the design, it elimiinates the cahnce of Check Engine Lights and bogging (sounds liek ur engineis struggling becasue it is not reading correct amount of airflow.) So for intake and exhaust i woudl et tpr on both.

Now with shifter, TWM is harder to shift becasue it is so short. I have herd of people saying they ocassionally misshift becsaue of the shortness of throws. That and it is much stiffer. Apparently it is difficult to get into reverese. So if ur good at shifting and want a fast shifter for say racing get twm. If you want a daily driver with shorter shifts and tad shorter shifter get B$m

1. tpr has hardly been dyno'd. should be ok but i have my doubts. get trd instead.

2. tpr nobody knows. should be good but i have my doubts. get the aem gen 2 (v2) cold-air intake or if you want shortram go with injen or rmm (only if you have a manual though).

3. b&m.

sorry, but i don't recommend products that are not dyno-proven. whooptie-doo i can find maybe 2-4 dynos on tpr products. everything looks great but again, i will not recommend them until i know more. and i honestly can't see how anyone else could

if you do go the tpr route though, please dyno them and post them up so i won't have to keep saying this

1 exhaust; TPR seems real nice and now that they have pictures it's shinny and pretty, but again the wait in the past there have been very long delays he doesn't stock any he has you pre order them then makes them, thus no risk to him in initial investment, but also means very long wait for you and both you and him are at the mercy of the exhaust shop. TRD is best after market major brand, they are expencive though(gts extended for body kit is 550 + shipping at lowest price), www.hopupracing.com [hopupracing.com] has greddy evo 2(all stainless steel) which in a comparison dyno only scored .2hp lower than the trd and it's 500shipped, but so is the tpr if your willing to wait for it. (shipping for an exhaust is usually between 50-100 dollars so when buying online calculate that in)

2 intake; even though it hasn't had a lot of testing the TPR looks like a really sound design, since it makes the maf housing exactly like the original housing and gives it a good straight shot to the maf so there is a better chance of a good reading. You do have to cut your ECU cooling tube to install it though so it could have side effect of messing up your expencive ECU. The AEM CAI seems to be the one of choice, and if you go on ebay and get the no name ebay intake it's an exact copy of it for 40 bucks instead of 250. a short ram has a lot less likely hood of hydrolocking becuase it sits in the top of your engine so unless your in 3 or 4 feet of water you should be good opposed to a CAI whcih is located in your fender well and could be submerged depending on your drop in probably 18" of water. Injen is the prettiest and best it's the TRD intake

3 don't know much about the shifters.

B&M has the shortest throw, but TWM is physically shorter. As far as exhausts go, the TPR doesn't make more power, it just adjust your power curve. You lose some lower end power, but that gets moved to the higher end, so you peak power is greater.

exhaust, TRD or TPR.

intake, ebay AEM replica, AEM, TPR(probably won't be available for 6 months maybe more, haha)

Shifter - TRD is only true short shifter that doesn't just change length of rod. Only problem is only works with old style shift gates.

1. TRD

2. INJEN CAI

3. B&M

Enough said...

Is this true, I am looking for the shortest throw, not the shortest stick. And is there any way to check when the CAI from TPR will be ready I thought people already had them. Where is TPR based out of? Also, does anyone know exactly how much better the TPR exhaust preformed over the TRD, since if it isn't much of a difference, I might have to go with the TRD and not risk/wait for the TPR.

~Alex

dude, screw it and get the car in your sig..its a beast!!
its prolly the only car in history to lose hp while driving...

if the stuff they say about 10whp is true tpr is twice as good as trd gives you about 6whp. if your in a hurry though you could probably have the trd by the end of the week. look to wait a month or more for a tpr exhaust.

Ok, I am going to pull a noob question what is WHP I know it is something about horse power, but what does the W stand for.
What are the BHP gains.

~Alex

ouch.. whp is wheelhorsepower, what you actually put to the ground
bhp is power at flywheel, what matters is gains to the ground

^^Yep. The only way you're gonna find out horses at the crank is to hook your engine up to a flywheel dyno, which is a pain in the ass and is expensive. BHP I think stands for Brake Horse Power, it's a measurement used quite some time ago and there was a lot of math to it. Today it's kinda gotten morphed into Block Horse Power.

So TRD provides a 6whp gain, and TPR a 10whp gain? Is there really a difference between 6 and 10? Seems like a small difference. I am trying to decide if the TPR's 4 more whp is worth the wait.

~Alex

tpr soudns louder then trd, but still not bery loud. also not a big fan of the tpr tip but oh well

i love my twm ss, had it installed for almost a year now.

Is all of this true, I am looking for the shifter that reduces the throw the most, not just the height. And if the TPR exhaust on;y "moves the power" would TRD and TPR run the same times?

~Alex

Ok, here is the set up I am thinking about. I am not sure if the difference between the TRD and TPR is worth the wait.
So I am thinking TRD exhaust, INJEN CAI, and a B&M SS if it does infact have the shortest THROW.
How well will this set up work, or are there any better manufactures out there for these parts.

~Alex

wait for tpr exhaust is not long, if your going solely power it is worth the wait, like 3-4 weeks max i believe.

Get TRD exhaust.

Get TPR Intake or AEM v2 for CAI.

Get Injen for SRI

Get TWM for SS

Who do I talk to to see if there is group of TRP exhaust getting ready to go out, or about what the wait would be.

~Alex

Is there a AEM V2 CAI for Celica on the market yet?

naaah he means the 2nd gen AEM intake...not the V2 like they make for the RSX...

i aint got shit on my car performance wise due 2 lack on funds...

however

Go with TPR or TRD exhaust
for intake...AEM= lower end power
Injen= high end, but lose low end at least on SRI not sure about CAI
TPR= says to have injens high and aem's low and you can convert it from SRI to CAI...

i have an auto so no help with shifters

Celica_Noob, pm Easy_C. He's the owner of TPR.

How could I overlook this thread???

Anyway I'll clarify my experiences and my customers experiences with my products as well as the waiting questions and what not.

1) The exhaust doesn't "move" the power band. Its a totally different band than TRD or Stock. The design is significantly different than TRD. Most people would lead you to believe that just having a free flowing exhaust will make the most power. While thats a big part of the equation, controlling gas velocity and direction can have a substantial effect on an exhaust's performance.

I'll start with bends, since its the most obvious. TRD has 4 (approx) 90 degree bends in the piping as well as a 180 degree U bend in the muffler itself. This means the exhaust gas has to travel a total of 540 degrees of bends before exiting the tip. While TPR has 1 more bend, the total degrees of bends are less than that of TRD coming in at approx. 450 degrees.

Next is exhaust gas direction. Obviously it requires more force for exhaust gas to change direction in a bend rather than continue in the same direction of a previous bend (pending the pipe length between them is short enough, otherwise it would be linear flow for both cases going into the bend). TRD's bends are in this order, RIGHT, LEFT, RIGHT, LEFT, RIGHT (in the order of flange to tip). TPR's bends are RIGHT, RIGHT, RIGHT, RIGHT, LEFT (in the order of flange to tip, respectively)

Another crucial part of an exhausts performance is the muffler. I don't really know the compositional differences between my muffler and TRD's so I can't really comment on that. I just know my muffler sounds great and dynos great.

With that all being said, I've had quite a large percent of the initial 10 customers who claimed a nice gain thru out the entire RPM band (low, mid, high). To say that I "sacrificed" one part of the band for the other is false. The exhaust did make 10.5 whp peak and 32whp at 6300 RPM ON MY CAR. Will everyone get that much, most likely not. My car seems to be somewhat of a beast when modded.

2) The intake pretty much speaks for itself. There are numerous customers out there with the intakes. If you do a search you will find nothing but good reviews on this site, teamcelica, and new celica.

Yes the intake did dyno with AEM's low end and Injen's high end. Yes those are confirmed as there was another celica member present during the runs.

3) The wait time. Well, I'm just an average guy who knows a few things about physics and cars. I love my car and saw that the aftermarket was somewhat lagging. So I decided to design something better, and consequently market it. I am NOT a millionare, hell, I'm not even well off. I didn't have the money up front to get 6 million things made for selling. The ultimate chain of events with shops screwing me over and taking my money didn't help either. Luckily I finally have a reliable shop that does quality work in a decent time frame. The exhausts are already shipping, however the amount that I did buy (which was more than needed initially) may have all the spots taken up (I'm gonna double check availability tonight). I'll be forced to do another group buy because of the financial mishaps with my previous shop (who turned out to be a fraud). There will be a post by me regarding TPR and its products sometime in the next couple days to alert everyone as to shipping status and production status and where I'll be taking it from there. But of course, as always, any orders will greatly help speed everything up. I'm open to questions.

and for you cali guys the TPR exhuast would be great. no CARB # needed as all axle backs that register below 95db is legal..sweet!

i have a TRD...but if i had to do it all over again i'd go with chris' exhaust. i've seen vids, dynos, and customer reviews. can't get any better than that

Torque?

BTW, I was in the first 10 to receive the TPR exhaust, and I can say that there are DEFINITELY gains made throughout the entire rpm band. The most prominent gain that I could feel with a butt dyno was the low end. Getting of the line seemed much easier and smoother. As for the design of the exhaust, everything lined up perfectly and the thing seemed very solidly built. The sound is very good, and I have a friend with a TRD exhaust that will swear on his grave that mine is making more low and mid power.

TRD exaust
injen CAI
b&m is too stiff

Not trying to jack your thread Celica_Noob, but I have a question about the TPR exhaust. I don't like the exhaust tip, so is it possible to get the exhaust but cut off the tip and put a Tanabe muffler at the end? I like the look of a whole muffler ot the end, not just a little tip. So is this possible or am I going to ruin the exhaust design and won't gain as much? I don't see why it would ruin the design tho?

2 mufflers won't ruin the design... lol... yes it will ruin the design, changing to a new tip is one thing changing to a muffler is another.
