I'm going to race TypeS this friday.
how bad will it be? my only weapon is header and intake. would it be close battle?? or not even close???

 

Header & Intake, should be pretty close...Let us know...

------------------
2000 TL - Laguna Green, Navi, Rear Spoiler. PIAA Hyperwhite HB's. 17" CL-S wheels with Bridgestone RE 730 - 225/45/17's. Soon to have Comptech Suspension, Sways & Axle back Exhaust.

 

Those two combo of header and intake, should give you about 20 horsepower, should be pretty close to a stock TL-S...let us know the results...

------------------
2000 Satin Silver TL, 17x7.5 ATP wheels with Pirelli 215/50/17 P7000SS, H&R OE springs, OEM spoiler, K&N filter, Tint all Around. Inspire Foglight Switch, PIAA 1700X fogs, Polarg M-12 corners.

 

Uhh.. i think you'll need some good luck. so good luck. And I seriously doubt headers and intake will really give you 20 hp.

SHoof, howz your face ??? C'mon I wanna shoot that damn grinning face !!!

S.HOlla ...

 

If I'm not mistaken hasn't there already been people who have posted dynos after comptech headers and shown +25 hp gains???

25hp gain from headers alone? Okay, unless things have changed seriously from preludes to TL's... no way. I remember people would have to get headers, intake, and exhaust to get like 22 hp. i wish it was that easy tho man.

so how much HP header alone gives???
who said the header alone will give me 20HP???

 

There are a couple of TL members here that had dynoed their TLs with before and after result, and it does show gaining of about 25 hp. Also, some Type S owners have gotten over 30 hp to the wheels.

I think a lot of people miss the point when they say "it adds 20 hp." To calculate real difference in power you have to take the area under the curve. The headers and intake will only add significant HP in the high end of the powerband whereas the tl type S's stock power is probably significantly higher in the low end of the powerband as well as the high.

 

Things have seriously changed from preludes to TL's. There I said it.

Things like 1.5 times displacement, and 1.5 times as many cylinders.

For real though, the stock TL exhaust manifold is restrictive. The Comptech header is pretty high flow, so the gains are pretty damn big when you can get something that's not a choker to begin with.

And for once I think rice has a good point to add to the story.



I agree. Whenever anyone says "gains 20 hp" they mean peak hp. I think they should pick a designated rpm, like the stock power peak, and just measure hp gains there, so it will be uniform.

You always hear people saying "Well I got an intake which is 7 hp dyno'd, headers, which is 20 hp dyno'd, so I must have 27 hp." Which is not necessarily true, and most often NOT true.

The reason is because the 20 hp is just peak hp gain, suppose at 5800 rpm and also suppose it hiccups at 4000 rpm where the gain is only 2 hp. Well now what if the intake's peak hp gain is 7 hp at 4000 rpm, and kinda goes lean on the top end and loses a hp at 5800 rpm? Whoops, total gain at 5800 rpm is 19 hp, and total gain at 4000 rpm is 9 hp. Nowhere in the powerband is it 27 hp over stock. And no one should expect it to be that way either.

I saw comptech's dyno chat and it shows that
"17.9HP was max gain" "header+muffler"
So i'm looking at bout 20 HP gain. huh??
260hp vs 245hp "still -15HP"
What other options do i have??
Does Oil change helps? how bout spark plug?
oh by the way.. does any1 got new MSD ignition???

 

HOT, the 20 hp from your headers and intake are probably closer to 25 at the crank, because of what you lose through the transmission to the wheels. The 225 and 260 measurements are taken at the crank so you're probably closer to 250 vs. 260. Just an estimate... Of course the Type S has grippier tires yet has larger wheels...

i got stock wheels on right now with new tires. Does Type-S rims are havier than 16" rim?
LIST ANY POSSIBLE UPGRADES i CAN make!!!!
(dont say something like"get a turbo or NOS..please.")
so i'm pretty much looking at 250 VS 260?!

 

Shit if thats the case i think i'm gettin headers. I never knew the stock ones were that resrtrictive! i do know preludes stock headers are quite good, in fact Gen 4. rally preludes used the stock headers.

Rice: certain headers/exhaust affect the lower range, others improve higher range. I've seen this reported in the Great headers test. I believe that was the name done by SCC mag. a few years ago.

 

Denso Iridium Spark Plugs...Mobil 1 trisynthetic 5w-30 motor oil...getting some bendable duct hosing that is about 6-7 inches in diameter and routhing that through the front air dam to your intake (cold air effect), underdrive pulleys...I think with those and headers and intake...I think you can take him!

You cannot compare a four cylinder to a six. Adding an exhaust system on a Corvette makes a huge difference in horsepower. If you have done any flow analysis on engines, you would realize that a finely tuned exhaust manifold can give you an increase of 30% in horsepower. There are other factors that go into that, but seriously depending on the engine, a header and intake install can give you easily 20 hp on our 6 cylinder engines.

I am not claiming that it does, but it is dependent on many factors. So, don't be pessimistic. Also, the Type S might be a slow one. Never know.

The headers and intake will help, but the big problem you gotta watch out for with that Type-S is the dual stage air induction, that's what's going to kill you. The Type-S has a much much much flatter torque and hp curve because of that, so he'll be pulling hard no matter where the RPM range is. IMO that's where the Type-S excels, yeah sure it peaks higher, but it's also flatter and that is what ultimately results in it being quicker.

 

Whatever happened with this?? I want to know!

I think the biggest differences race-wise btw the Premeium and the Type S would be the launch. I've seen a couple 0-60 vids of Type S's, holy cow they launch substantially meaner than our non-S's.

After I drop the break and bury the throttle, the tires squeal for a second or more and then there's a short lag period where the car is kinda figures out its rpm and speed, then the torque comes and you get goin like normal.

The S just blows right through the launch, right after the tires squeal, its off, no lag time after that. And that's what I think makes most of the difference.

If you want a closer race, go from at least 35 mph, where you can put the car in high rpm's and get a good momentum going.

I think the best you can do within reason is, intake, headers, exhaust, high flow cat (or test pipe), plugs, pulleys, v-afc.

That's a good basic start. I spose if you're really into it, you could do a throttle body. Ours stock is 64mm and the type S's is some 68mm ? or maybe ours is 60 and theirs is 64. Anyways, the Type S's TB is substantially larger, and along with it you'll need an intake manifold port match. (Type S TB costs around $180)

An Accord V6 owner is working on a Type S intake manifold transplant, but its expensive. ($900-$1000 for the part alone) Then you've got the install. Gotta find a way to actuate the butterfly valve with rpm's. I'll keep checking with the Accord guy and tell you all if anything's up. That's the Type S's main gain in torque.

A 2000 TL with i/h/e/vafc pulled a type s on the highway I believe. So with pulleys and a cat you'd be in good shape.

at the local dyno store the comptech headers were shown to give a 18 hp gain at the wheels for the TL and i think it was 28 for the cl-s. i actually saw the chart for the tl because i didnt believe the guy when he told me. he did say that it was an unusually large gain for headers. guess the j series engines just have restrictive exhaust manifolds. as soon as i get a grand i am going to have the headers.....

28 hp from the headers?? Sweet. This is a mod I definitely plan on doing.

One more thing, the TL-S weighs a bit more than a TL-P, so if modded well, a TL-P should make it a close race

 

Major diet on your TL is a plus!

 

Nah...I had Headers, Intake, exhaust, VAFC and total HP gained was more like 25 HP or so.

 

Ahh, that would be me! Plus I had 18's on. Remember, everyone that said headers helps on the high RPM range is right. I did not notice much power gains in the low range, but in the high end you notice your RPM's racing faster.

 

Hey Hot, how did the race go?

 

and the type S would be me. He did infact pull on me a little and Have to admit his tl was a pimp ass fast car. but now no chance. and yes the type S get around 29-32hp w/ just headers alone. hard to believe until you see dynos. I raced numerious stock type S's w/ my headers on and would get 2 to 3 cars easily by 80. For the Type S a headers are a must.

ok. I raced this guy works at jiffy lube.
his car was tatally stock cl type S.
After i changed oil i suggested to race each other. anyhow here is the results.
from 0.. he pulled on me fast.(one&half car length)
from 75mph. i somehow managed to keep even speed w/ Type S.(guess the header works.?!)
raced until 143mph.
So i guess from 0..you can't win over typeS.
however High speed racing can be pretty good match. I couldn't pull but i could pretty much manage the same speed with type S. (I used 3Rd gear till 115mph). i removed spare tire and 1/4 gas.
