What do turbo cams gain in hp and time #'s?

[Megags]

I was wondering if any of you have any before and after results of hp, or more importantly time differences.

Someone over at dsmtalk a while ago said he went from 16.4-16.6 to 15.4-15.8 with other mods as well.

Just want something solid as to what to expect.

I guess fewer people have done this than I thought... If anyone is interested in the findings, I will post my own results.

if you are just putting the cams from a turbo car in and not aftermarket ones, dont expect to see a big difference...unless you have some head work done (ala porting, bigger valves and springs) you wont really take advantage of the cams. as far as a full second shave from a QM time i dont think that would happen...anyone else have an opinion on that? the only difference between the NT cams and T cams is a more aggressive grind, so those valves are working a lil harder and more efficent, but unless you have really opened that head up, actual performance increase would be minimal.

IMO there's no way cams would shave a second off of an ET. If the Turbo cams do have a harsher grind, more lift/duration or whatever, then you should see some increase, with headwork or not. I think more importantly a more free flowing exhaust and intake setup (i.e. GM MAF instead of the restrictive DSM one) would be needed to reap the benifits of the cams. The turbo cams should be a dime a dozen, so if there is a gain to be seen it's probably worth the money. If anyone has results of putting turbo cams in a non turbo please post them, i am also very interested in this mod.

I have put the turbo cams in my car. It helps out with a little mid range and top end. It really lets the engine breath up top. If you get them cheap then they are definatly worth your money. Im not saying i got outragous pull or gains out of these cams but they are just better then stock. In the high rpms you can really hear the engine roaring and pulling in air. Fun

exactly....

which is why porting and oversized valves and springs help so much, lets that meant for turbo engine breathe and you can rev the hell out of the motor

The head doesn’t need to be ported, the head flows extremely well.
I did the conversion about 7-8 months ago and noticed a diff at high rpms, and the car doesn’t slow down after 6000. I also have an udp, ram air intake, and exhaust system. My car is running mid 15, and on cold days it's sub 15 secs. The cams deffinatlly won't give you a sec off the 1/4, I would say about .3-.4 secs.

do you honestly run a mid 15 NA? i raced a probe and sprayed my 60 shot and i only ran a 15.9 at 93mph (this is according to my g-tech meter) i have a nice intake, muffler, headers, and the N20. mabye my g-tech was wrong..

Just posting because this thread asked for definitive explanation...

I installed some 92 gst cams and noticed a small gain, possibly just a newer camshaft that makes my car run better.

However, my car is running extremly rich and needs to be leaned up a good bit and ignition timing re-adjusted since I retarded it when I reinstalled the cam sensor.

im doing a rebuild right now and about to put some stage 3 turbo cams in my 93 eclit, im hoping for some mid and high gains. ill post when i get results.

 

[Megags]

The computer must have learned the new cam or something. Seems to pull noticably harder now. Now to get rid of the low rpm hickup it has...

 

[jdm93dsm]

are you using stock turbo cams?

what exactly do u mean "Now to get rid of the low rpm hickup it has..."
doesnt the cams help w/ that? do u get anymore high end performance? i know w/ my stock nt cams it wouldnt do shit like over 5k... hopeing these turbo stage 3 cams and high pressure valve springs fix that.

 

[Megags]

My hickup is because of too much gas being shoved into the motor at idle and then when you hit the gas it almost stalls then ignites. I have my afpr set way to high.

I noticed a good gain from 2500rpm's and up, the farther up I went the more it pulled. It tapers off a hair at 7000rpms, but still much better than stock. It has nice topend now.

I whipped up on a late 90's dodge ram v-8 by about a car even though I missed a shift and even though he launched and I didn't(didn't think he wanted to go); if that tells you anything.
