It looks like a good friend of mine is getting a solid roller 427 built by Jim Barth. He is wanting to put on a power adder, and likes the Procharger units.

Who on here has one of these units on there L-98 Gen 1 style motor. How was the fitment, and any did any problems arise? He is wanting to make power in the 800-900 level.

Any pics as well would be awesome!

The D1/F1 will fit without issue. Both of these blowers are 9" volute, so no issues. When you go to blowers that are larger than the 9" series, there are significant concerns with clearance (head, vc, hood, and fenderwell).

The main difference between the D1 and the F1 is the fact that the impellor on the F1 can be pushed to 70K, vs the D1 limited to 65K. The inducer is larger on the F1 while the exducer is smaller, all leading to the ability to move more air (1525CFM on the F1 vs 1400CFM on the D1). The R-series move to a 4" inducer, and reduce the impellor speed, but deliver in excess of 2000CFM.

The D1 is the largest ProCharger unit that has "off-the-shelf" brackets available. The larger blowers require custom brackets. Drive systems also become extremely important when trying to push very large quantities of air into the engine.

Search under my SN, and you should find plenty of pics of the old D1 set-up as well as the R-series blower and all of the custom work to make fit in a C4.

Aaron,

Shannon, a tech (i think the best one there) at procharger, told me that the bolt pattern on the back of all of the self contained prochargers is the same.

Of course the procharger c4 corvette 6 rib single belt brackets are prone to belt slip and thats a whole separate issue onto itself.

This would lead me to believe that one could run up to an F1-R, provided the 9.75" (vs. 9" on the D1) diameter volute didnt contact anything. Really bigger than that even, but Im sure the volutes of the huge units would have clearance issues somewhere.

An extra 3/4" of volute diameter doesnt seem like much. Of course clearance issues on our cars are unprecendented.

I had greg at blowerworks design and make, for me, a special 8 rib dedicated drive bracket for my trusty p600b. Which interestingly, procharger appears to have downgraded it from an 1200 cfm to an 1150 cfm blower on their spec sheets. If you lookat old spec sheets it lists it as 1200 cfm blower. Im assuming it really is a 1200 cfm blower, but they downgraded it for marketing reasons.

procharger advised that the D1 on a 427 would not push 15 lbs of boost. looks like maybe the turbo route.

the d1 has been low 9's at over 145mph. How fast are you looking to go? Just because it may put out 10-13lbs on a 427 doesn't mean it isn't going to make power.

850-900 rwhp.

D1r, d1x or f series will get you there

You don't mention anything about the car. Is it going in a C4? You asked for pics, so I'll assume it's a C4, but some more information would help. Year, trans type, does it need to retain power steering, AC, etc...

Josh,

This is a good friends car. It appears that Jim will be building a 427 or 421 solid roller for him. Its a 89 ZF6 car. The car has the stock D44 in it. He has a miniram allready so that will be going on it. He has a built 355 in it right now, but he wants to double the power, and a power adder is the only way to do it. He doesnt want to do R&D hence why we thought the procharger was the way to go, but that direction has changed it seems.

Maybe a fabricated single turbo is the better way to go.

Procharger doesnt have brackets for anything bigger then the D1. And he doesnt want to chop the hood up, and have anything look fugly.

But why would you want to use procharger brackets?

All the procharger c4 brackets are single belt setups prone to belt slip.

See if you can get someone, like greg at blowerworks to fab you up something that runs 2 belts. 8 rib for the blower and 6 rib for the accessories. That's the onle way you get that uninterrupted 180 degrees of belt wrap that you need for slipless operation
