My goal is about 850 or so to the rear. Not a big track junkie just want more! I think 850 would be a blast, not that 637 isnt already.

I have a Procharger D1 with 6 PSI now and am going to go with a forged bottom end stroker 416/17/18 Cubes etc.

My question is if i go forged can i make enough boost to get to my goals or is the volume on a stroker going to be too much for my D1? So you centri guys get in here and let me know.

As always, thanks! Really dont want to drop 4K for an F1R head since i dont really need 1000 plus

I would like to way in on this , I had a D1 on my 2010 camaro Heads/Cam A6 on 14psi it made 670 to the tires , but my dyno is stingy [ it trapped 134.89 mph in full street trim with stock gears and converter ] ... I would say if you keep stock cubes with D1 it will be close , IMO I would sell your d1 to someone with an P1 and just bolt in a F1-d this will get you the same curve as the D1 and deliver the WHP your looking for on either a 376 cid or a 416 ... This allows you to keep all of the brackets/piping and inter cooler ... You will need a fuel system to boot ...

Centri cars don't have the massive torque hit on launch that a PD blower does....so you may be able to get away with the stock trans for quite a while.

It varies of course but with the linear power curve of a centri then the trans has a decent chance of survival.

Thanks, thats what i figured, one the main reasons i went centri!

How much torque at launch? Whose car is this?

i agree. i know of a 2010 camaro with 1000ft lbs@3500rpms(92mm turbo)with the stock tranny. all he has is a twin carbon disk.

Black10, are you on the stock bottom at your HP? how much boost are you running. My plans are to pulley down the my D-1SC for 3 more lbs of boost to about 10psi. I am also adding an Alky Meth setup tuned for safety not power. relying on the extra power from the extra boost. I should be about 700 or so at the wheels. How has your centri setup been if it is indeed on the stock bottom? tried PMing you but dont have the option to when clicking on your screen name

He doesn't race it then.....a cause the stock tranny won't take it with traction and a twin disc won't last long at 1000ft/lbs either...again assuming traction.

Street tires....it could live a happy life just fine.

You can live at 10 psi with meth a LONG time ....especially if it's a street car.....and being a centri just makes it that much easier on the drivetrain.

I wouldn't be afraid of that combo on a stock bottom end at all...assuming your tuner knows what he is doing.

Thanks, the plan till i do the stroker is pulley down on the D1 from 4.38" to 4.13" maybe 4.00 if im feeling really ballsy. Should be at 9 PSI up 2 Psi for an estimated gain of 50 or so to the Rear wheels....685-700 RWHP. Also Alky Meth system used only to cool off the extra boost and not included in the tune. Relying only the boost for the extra HP.

I am in the same boat as you with my D1. I ordered Vengeance Stage-II Cam and I will be pulley down to 3.85 or 4.00 what ever gives me 10 -12 psi of boost. I have the Snow Stage3 meth kit for the same reason and will add race gas when i go to the track. Good luck, keep me posted how you do with the pulley change. I am hoping for 650 rwhp or higher.
