Ive got a 4.1 cross flo (cast iron head) Im experimenting with a 6 and a turbo ive picked up from Volvo truck. Ive put the extractors on the head backwards.
The pipes face up and front.
(Its a burnout car so its never gunna see the road and Im not scard of blowing it to pieces) so im makin an adaptor plate to the extractors and im puting a 465 new genaration Holley on it, Ill have to modify the bonnet to suit but thats a minor detail. Ive got a pressure hose into the cab on a guage, and another hose with a ball valve to dump the excess pressure. So getting to my Question how much psi (pounds per square inch) will this engine handle? This engine is totaly standard.
Im going to give it 5-6 psi to start at home but when it comes to the compition run im liklely to up it to 10-12 psi so so what do you guys recon?
P.S Borg warner 35 tranny 4.00.1 Diff gears in a XC Hardtop Falcon.
Thanks Baz

some type of cooling of the charge air will be neccasary for 8-9+ psi.

i dont know how strong those engines are but to make it survive it will need to be tuned pretty well, regarding air/fuel ratios and ign timing throught the rev range.

whats the a/r ratios of the turbo?

Ive put eletronic ignition,new coil, plugs, leads, cap,rotor button etc.
I recon a 465 will be enough fuel/air to run it very rich. I have a webber aswell but I think the Holley will run richer. And I dont know the a/r ratios are.
As for cooling the charge air. What do you recon about water injection.Possible from a washer bottle.
