"We did pretty good with blower cars for some time and I was in denial for a while, but we had a customer come in one day who really wanted turbos." "We set out to develop a turbo program, and after just one trip to the track, I was done designing supercharger systems completely"

"Jason Heffner of Heffner's Performance"

:yes:

Absolutely, turbos are THE way to go.

I read that article too, and with only 3 ~ 4 psi more than what they were runnng with a Pro-Charger, they picked 300 RWHP.

I also liked that they are going after the fastest IRS record currently held by the MSP Supra @ 7.90.

:eek:

You know I have a Lightning also. There is a big push now to replace the roots blowers with turbos. I am considering it myself, only hesitation being how tough it will be to get through smog.

There's a couple guys who have theirs up and in the middle of tuning, but initial numbers show gains of over 100 rwhp at the same boost, and this is compared to the race screw blowers not the stock Eaton units that come on the trucks stock. Plus the biggest drawback for me is that at highly modded levels the trucks need a full exhaust, which is very loud with the length they use (side exit). The turbo would eliminate that issue also with it's natural "muffler" tendencies.

Yes, I am thinking of it for mine as I already have a fully built engine, ported heads, bigger cams, KB screw blower, etc.

I would love to help out any way I can, turbo selection, or to help get past the smog Nazi's. After all Gale does have a street legal Dakota with a 800HP diesel in it. ;)

We may have to talk in a bit! :unibrow: I'd love to do it. I do my own tuning on the truck, and I know I can pass the tailpipe portion. The correct turbo would be awesome.

What is the most HP anyone has made with a factory block?

There's been a few over 800 rwhp. I think the block will take more than that, the limit being getting the truck to hook. I know a few of these guys run nitrous as well and are making 900 to nearly 1000 rwtq with the 331 cid engine.

They all seem to use the factory crank which is supposed to be good for 1200+ HP. I also have Crower billet max-lite rods, custom CP blower pistons with Swain Tech coating, etc. Mine is made for big power but I'm at about 600 rwhp currently on 91 octane. That is with 100% stock exhaust due to noise and that this is a daily driver not a race car. I am installing a full exhaust today just to dyno and figure out how much I'm giving up power and torque wise. Then if it's significant like I think it is I'll try to quiet the exhaust.

I'm at 20 psi (street) with the KB blower.

Jody or Jason,what is the deal with smog,is it the visual part?I can't see the roots blower running any cleaner than the turbos.Then again what do I know. :_paranoid
