wondering what are the limits of a D1? this D1 was for a LT1 that pushed a blazer to 10.30s. some of you might of seen that same blazer with a F1r on it

im sure i could contact ATI for the brackets but was wondering how well would a D1 work on a 408

the lowest i could drop CR to is 10.1 but motor is fully forged. its a complete lunati 408, with claimed status of 1100hp holding ablity

right now i figure i should be in the neighborhood of low 5xx NA to wheels. what figures if this blower is possible would i see to the wheels. remember my setup would be L92s/L76 backed by a proshifted t56 and 14bolt. not worried about driveline. and i know i would have to get a different cam then the one i have now

i know the blazer with the LT1 355 made around 800 crank before with this D1

 

thats a lot of compresion. the blower should feed that motor just fine but you better count on race gas for anything over a few psi. that blower is rated at 925hp so i would guess 700-800 rwhp in your truck if you cranked it all the way up.

 

thats what i was kinda shooting for. figure high 7xxrwhp/low 8xx rwhp would be what i wanted.

now wondering if that would be enough to come play with you, unless you step up the game for 07

how much psi you think on street would be safe on pump gas

 

Im pretty sure it'll get you where you want to be. Buddy of mine who I got my blower from used to work for Procharger. He did a Pretty much stock LS-1 vette with a D1 and made around 580 whp on it. So with a built motor your size I think you'll make the power you are looking for.

 

amount of boost depends on a lot of things. cam, heads, fuel, timing, intercooler......

go for it and let us know how much you can run but you better roll around with a lap top so you can watch for knock.

 

that is a lot of CR to be running boost on pump gas. I woudl say stay around 6-7# max with out come race fuel. Also, as you know, make sure that tunning is dead on.

What does your fuel system look like. I know ou have talked about it in other posts, but I am at work and to lazy to look it up

 

I think the compression is fine. You should be able to run 8-10psi on the street and around 12 on pump fuel without problem. That would make for some pretty decent numbers.

 

yea i knew with this idea of boost that the truck would have to be "dead on" with that amount of boost

has anyone ran a setup like this and any idea on actual figures

 

Wondering myself. Trying to decide on optons for my 408. Rebuilding my p1 to a D1 would be cheapest. Love my buddy's radix though.

 

Do you plan on Water/Meth as a safeguard in case you get a tank of bad gas?
