crane 272 cam with boost..

[FastGT31]

i have the crane 272 came in my 91 3.1L. is this too much cam to put a turbo on?

Probably not, I've looked at the specs and they seem decent for a turbo application.

I'll probably be swapping from my 260 to a 272, depending on how this one looks that I have had offered to me.

i probably should write an article in the boost section but what kind of turbocharger would be good? i was reading over there and there are so many opinions. i dont want instant boost, more like power after 4K. any suggestions?

I have a 2.8 with a supercharger and a 272 cam. I dont think its the best cam for my application but it was a decent price and readily available. I had previously run a 2030 on a older high milage 2.8 with stock heads and a worn out blower, so comparision wise I dont really have any data like dyno comparisons.

who did your chip, and how does it idle? i'm considering this for my future 3.1/3400 hybrid. any drivibility issues?

RE: Re: crane 272 cam with boost..

jet performance did the chip. i had to send them my stock chip and all the modifications to the motor and it came out real nice. i drove the car with the stock chip for a while and then put in the custom one and it was a big difference. the nice thing was that i was never charged for it, so i actually got it for free. drivability wise the car runs nice. way too much power down low and the thing pulls like no other V6 or turbo 4 i have ever been in for that matter. it doesnt hurt that it now has a 5-speed, JBP headers, 62mm throttle body, ported/polished heads and just about everything else except a 3400 top end swap. u will love the midrange power, especially is swapping to the newer intake manifolds, something i might do next year.

sweet deal! i love the down low torque!! make it very flexible. not sure if i still want to keep the 125C though. i'm worried about the torque capacity. what car do you have this in?

RE: Re: crane 272 cam with boost..

its a 91 beretta gt. i used to have the 125c as well and i had it rebuilt and it was nice trans but couldnt handle the new motor. shifting started to get soft so it was time for the 5-speed swap. as with most people here, i highly recommend swapping to the 5-speed if u can

i forgot about the idle. i have it set to idle between 600-700 rpm. motor sounds so sweet with the cam. i always get asked what is under the hood and people do not believe me when i tell them its a V6. it sounds like a big block, just a little quieter. the lope on idle is something u would just have to hear, its that nice

Well...let's hear it!

[FastGT31]

if i only had the ability to get u guys a sound clip. i have never done that before and wouldnt even know where to start. im still trying to get digital pics of the motor and stuff. no one seems to believe that my car has headers on it. expensive little b*stards but what a difference in the power

[torq455]

i've heard it in my current stock 3.1. sometimes when i first start it and let it idle and warm up, it begins to stumble and get rough. then, it sounds nice and lopy for about 10-30 seconds and smooths out. i just stand behind it and smile. reminds me of my 455H.O. 66 GTOmmmm....anywho... did you have a stock rebuild on the tranny--shift kit--kevlar clutches--anything? and how long did it last? like i said, i want that cam and the 3400 top end swap so i hope it won't break.

[FastGT31]

it had a stock rebuild, shift improver kit to correct problems that are common i guess in the trans, i also had a 2750 stall converter from a quad. it was good, it didnt actually fail completely, shifts just werent as firm as they were when it was rebuilt. plus i always wanted this car to be a 5-speed car so the swap was perfect

[torq455]

you know about how many miles the 125 had on it when you noticed it soften?

[FastGT31]

it had a total of 15,000 on it since it was rebuilt, probably around 12K before it started doing it
