Ok so i've been searching a lot on these forums about how to make my 99 TLP faster. From what i see, the best and easiest mods are intake/ headers/ pulley and spacers.

Just want to know howmany people have the Comptech icebox, headers, spacers, and pulley installed on a TLP and howmuch hp gains they've achieved combined.

Also, what else can i do to make my car faster along with those things?

And howmuch hp can i expect with adding an aftermarket exhaust?

Thanks guys for ur help.

fsttyms1

with those mods you would/should be as fast as a type-s

fla-tls

Ah, but not as fast as the people with a Type S with an icebox, headers, spacers, and pulley installed...



(Hmm - need spacers!)

sbuswell

faster than a type s. I have headers/spacers/crank & alt pulleys/grounding kit/k&n filter both intake resonators removed(ghetto CAI) and today had a chance to from a 15mph roll to take on my friends type s in a nice straight two lane. we both took off hard and while still in first(SS mode) we both took off and where pretty much neck and neck, when I hit second I started to pull on him and in third had a solid 3/4 to 1 cl's on him I shut down at 75mph. I think I could have put some more room between us but not much. I was suprised, it was just a week ago we were neck and neck and he inched me out by 1/4 CL, then I had my pulleys installed last friday along with tranny drain and fill, oil & filter change and ran some octane booster on my first fill up. I couldn't believe how my car pulled. I am so excited! Now I need a real CAI. 99's can get fast, an exhaust adds only a few WHP 1-3 maybe. you can also get hyper voltage system(some say they work, I'll find out someday), you can do a port and polish on your IM & TB(my next project in the springtime, just got a dremel set). also you can get a hi-flow catalytic converter(not much proof there is one that creates an actual gain on the TL, but I see some popping up now).

Remember always get headers first, then intake, then pulleys, then spacers, then whatever else you want to throw in there. Good luck! Sorry for the long winded post guys.

I wish i had all those mods on a type S.

Wow, ur faster than a type S now? sweet. I cant wait to do these mods. Is it worth doing alternator pulleys and grounding kit? Right now i have a K&N drop in filter on the factory air box as well. What i like about the 99's is that u can hold the first gear. I dont think im gona bother with a exhaust system anytime soon.

I was thinking of getting headers first, then pulley, then intake and then spacers. What u guys think?

TLsu

Well headers on a TL-S are between 20-25fwhp....crank pulley is about 10hp at the crank...but ya gotta figure in the 21-24% drive train loss so it is more liek 8fwhp...exhuast is probably 3fwhp....icebox is about 12fwhp.

I think I have almost every bolt-on available for the 99 (except the S/C)

AEM intake
Comptech headers
Comptech exhaust
UR crank pulley
TypeS throttle body
Thermoblok spacers
Apexi VAFC (soon to be tuned)

I'm gonna port and polish my intake manifold then have my VAFC tuned.

varunverma23

TLsu: Do you know the specs for a TLP for those things? I guess it would be much less. 20-25 WHP is A LOT.

NSXNEXT: Do you know approx howmuch power you would be running right now? Did you feel any difference with a typeS throttle body? or howmuch it adds?

ChucksCL-S

I did everything to my '00TL and went from 15.6 stock to a (eek) 14.99@93.2mph. Just made it into the 14's. I now have an 03 CL-S with those same mods (see below) and did a 14.42@100.75. TL Mods: Headers, CAI, crank pulley, liteweight wheels, Mugan cooling mods and the Thermoblock spacers. CL Mods: Headers, CAI, crank pulley and liteweight wheels. Same track, similiar conditions.

sbuswell

crank pulley should deliver more whp then CAI. 12whp for icebox is not realistic maybe 8whp, 10whp for crank pulley is not unheard of. if you get headers then go straight to a CAI to bring out full potential of headers, then pulleys. I felt a significant gain with headers, a good gain with spacers and a very good gain from pulleys and probably some from K&N and grounding kit.

TLsu

And as I'm sure sbuswell knows...just stating this for noobs newer than me...the thermoblok spcers don't "add" hp they just prevent the lose of it by stopping heat soak in the intake manifold...am I right?

sbuswell

mostly right. they mainly function to prevent heat soak which in turn prevents HP loss by creating a cooler intake charge inside IM, but dyno tests have shown a HP increase also. OE's website shows dyno of a cl-s gaining 9whp and 11/lb tq. now i don't personally think the gain is that much but maybe. I did feel a gain when I installed mine, but that was on my butt dyno and I am skeptical about how much a mod will gain me. spacers are a great choice and even if gain is only 3-4whp the benefit is still there.

TLsu

Yeah, the dyno's show a gain...but it isn't "new" HP...as in HP created by a CAI or headers...it is HP not lost due to heat soak. Does that make sense...see the difference? or am I wrong?

FL3.2TL

Wow that pretty impressive, seriously I would never thought that a TL-P would compete with a TL-S, so that would be to the crank that a TL-P would push out 260 - 270? If so, you prolly looking into spending a good $2500 in all for the mods itself.

TL01

how much did you spent on all the engine mods man ?

sbuswell

i spent 300.00 for headers + 200 for install= 500.00, 40.00 for K&N filter, 75.00 for denso iridium IX pulgs, 110.00 for spacers, 40.00 for grounding kit and gold plated terminals, 130.00 for optima redtop, 190.00 for ur crank, alt pulley w/belts(used 2mnths by UglyPsyco) plus 100.00 for install= 290.00, total of just under 1200.00. I also keep very good care of my engine(clean TB, IM, EGR port, regular mobil1 full syn oil changes, changed tranny fluid, run fuel system cleaner every 5k change coolant every 6mnths, etc. 1200.00 isn't that much if you ask me a new set of CT headers costs that much. I bet at the crank I'm around 270 easy. Next will get a true CAI and hyper voltage MR kit. should put me over 280 no problems and cost another 350.00 and I will install myself.

Hockeyman

Where do you buy the grounding kit and hyper voltage MR kit?

JDMUA5

wuts spacers and grounding kit use forr ? thx

dvsxlt247

WTF, so your telling me i could be eqaul to a Type-S if not a little better then a Type-S???? With just that?? Also, what the hell kind of headers did you get if you paid only 300 bucks. Comptech headers are 1,000 and thats just for HEADERS!!!

varunverma23

MEgan headers are like only $300----sometimes less.

Do all the different makes of headers produce the same horsepower as the comptech ones? or are there certian ones to stay away from?

TLsu

All the different brands of headers give about the same gains.

All except Comptech have had problems. It's very frustrating because headers provide such great gains, but unless you bite the 1k bullet, you may or may not have porblems. It's all luck.


Quick summation for ya:

Megan: resonance in their early batches, problem usually solved after some inspection. Causes were bad gaskets and such. Header wrap was used to cut the thwart the resonance. MikePA, Elementz, and SatinSilverTypS are all well informed on Megan headers problems. I hope I spelled their user names correctly. The jury is out on Megans last batch.

OBX: Cracking...but some have not had problems such as Pure Adrenaline.

Alphawerks: Were deemed good compromise is price and quality at about $500. No issues were reported untill recently...when their fitment was terrible. penquinX and excelerate(the vendor) would be good members to contact about the headers issues. Very recent ordeal, I'm unsure if it has been resolved.


Do a search for details.

Excelerate

iTrader: (1)

Stay away from Alpha Werks headers until they have completely resolved their manufacturing issues. Their last batch of headers have been a nightmare for my customers and I. So, until they can prove otherwise, I recommend not purchasing them. Just go with the Comptech's = peace of mind. Also PM me if you need prices on any of the other items.

I've got Injen CAI, Comptech headers and catback exhaust an I've noticed some substantial gains. Can't give you #'s because i've yet to have a good dyno run. My next mod will be pulleys from Excelerate when my cash builds back up from the holidays and when the weather is a little warmer for install.

Yeah, stay away for AW for now. If cost is a factor, just go with Megans. The WORST that can happen is annoying resonance. You should get perfect fitment though. I had one of the first batches of Megans, and they've been perfect so far (got em for ~$200 brand new), but there is some resonance. Personally, I'm very sensitive to noise so they do bother me, but I don't think it'd bother most people esp. if you have a loud CAI that would drown out the noise anyway.

Oh yeah, I forgot to mention this:

I have the UR Underdrive Crank Pulley, and this winter I've had problems with my power steering belt screech. It's not a big deal though, it only happens when I have the steering wheel turned to either extreme, and the sound goes away in literally 20 seconds after driving the car. I don't have this problem in the summer or on warmer days, so it definitely has something to do with the cold.

The pulley adds a lot of power though. My car kicks like a horse when downshifting now, and the other day I actually chirped my tires on a dry highway when I accelerated to pass.

Just wanted to share my experience w/ the pulley.

sbuswell

I have Stone Racing SS headers. I got them from SSautochrome.com for 300.00 shipped. fitment was very good, but not perfect, gains were great and they still look perfect after about a year now. I wouldn't dream of spending 1000-1200 for comptechs when they don't provide anymore power. my stones are solid(LOL). and yes if you are thrifty you can get your tl-p faster than a type s. mine is already and there was nothing wrong with my friends car I simply beat him! cold air intake will be here later this week I will slap that sucker on and I am sure my car will pull a little harder. next hyper voltage system and then suspension(shocks and sways only).

TLsu

No resonance with your stones?

TLsu

What is the main concern/traditional problems with stones?

TL_Fo_Life

A TL-P can give a TL-S a run for its money, especially from light to light.

Elementz

I agree Penguin! Pulley = Raped-ape status..... In my mind it was equivalent to, if not a better mod than headers.
