Default Your opinions on a custom spec'ed turbo cam

This cam was spec'ed given the following:
3800 lbs
3800 stall
3.73 gears, 28" tires
stock short block
stock heads, meth, 10 psi
3" dual exhaust
Twin Turbo (APS)

222/222 .573/.573 114 +4

I know that I could make more with a bigger cam, but that's part of the reason for going turbo, I don't want a big cam, I have one now and it's getting old.

Opinion??

That looks fine Craig...... id just run a lil less boost on a stock motor if you dont want to hurt the stock motor for a while....... id stick around 8psi and be happy with that....

I don't drive the car much, so I think it should last for a while. If it doesn't it'll be agood reason to take things up a notch.

what are the advantages/disadvantages to running +4 advance?

I read that it helps get a heavy car moving from a light but I also read it was the same thing as lowering the intake duration. Any truth to either of those statements?

Hey,
Looks like drveablity would be outstanding. My advice also is stay around 8lbs. boost or less with stock engine. I have seen many. many, stock LS1's with 10lbs PSI ruin pistons; the favorite trick is they pull wring lands. Not safe for very long. As soon as you can i would go with a Callies/Drgon slayer crank; H-beam Compstar Rods/ and diamond pistons made for boosted applications. Really bullet proof for the street. You would have years of trouble free fun.

You really think so? It's not like I'm going to be pushing 1000 hp or anything.
Anybody else have any comments on the stall/gears?

I think it would be a better car, with 3.42's or even 3.23's esspecially if your running a 4l60e.

If im not mistaken , building boost is pretty easy with the aps stuff? They are street oriented and fairly small? 3.23's and 2800-3000 stall.
Better driveabilty and probably faster IMo.

I'm running a 4L80. Not too sure on how easy it will be to build boost, don't actually have the kit. I'm anticipating full spool by 35-3600.

Craig you will be fine with the converter the way it is..... mine is about that... maybe a lil more and i have less of a 1st gear then you.... and it was no problem on the street with a 28" tire and 3.73's..... and i didnt have OD like you.....

Should be a blast and instant boost when ya slam down the throttle....

who is doing the tuning for the turbo kit????

What all have you bought so far for the fuel system and what gauges?? Wideband???

Your cam spec is nearly identical to the one I had custom speced for me; and our turbo setups are very close. I am going to be running an incon setup, stock shortblock, stock 6.0 heads and shooting for 9-10 psi without meth.

I think your combo will run well. If it deosnt then mine wont run good either

Fuel system: Twin in tank w/ harness, rail mount FPR, evap as reurn, 60 lb injectors, and Alky Control meth kit.
Gauges: Trans temp, inovate wideband, boost

Robbie & I will be doing the tuning (mostly Robbie, I hope to learn)

The converter is fine for a streetcar and so are 3:73 gears when your talking a full weight car with a 28" tire!

So what's your definition of a turbo cam because that seems about perfect to me. Reverse Split cams are usually only for cars with higher backpressure and Traditional Split cams are usually seen in supercharged cars. Obviously, they do work in a turbo car as a lot of people run stock LS1 or ZO6 cams, which have a very big difference in duration, but it hasn't really been proven or disproven if they are better or worse. Additionally, that spec cam has -3* of overlap, which is ideal for a turbo set-up, and the 114 LSA will help his spool time and upper midrange power band. Not to mention that it will be fairly docile on the street.

Do you even need 28's you think? If not you could run 26's and keep stock gearing. How does that 4L80E fit in there?

The 4L80E swap wasn't too bad, it pretty much bolts right up, just a few minor things that need to be clearenced. It's really just a matter of buying all the parts.

I just said, I dont see why its a "turbo" cam....It fine, I d use it. I just dont put much weight in the cam or heads in most turbo cars. If your planning on 700+rwhp....ok then...and in that case, a 3800 stall will probably go to 4900..


Its weird I just made some small changes to a rear mount ss truck I did. It makes full boost (up to 15 psi ) by 2600 now...cruising down the freeway in OD just barely ease into it (not even downshift) and wam.....10-12-14psi .....goto retune a bit now.

The 4l80 is betetr gearing for you, if you put a 3000 stall in, and you make good power it will go a lot higher. I was running the tightest 9.5 vig they could make me, now with more power Im going up to the 10.5's in a lot of cars.
