could you make an FI setup with the C5r heads (they are around 35cc combustions chambers) and individual TB's...... (and yes i know how much they are so dont comment on that)

i have access to these for a great price and wanted to know if it would work or if i would have to run N/A or juiced.

 

I suppose you could with some very deep dished pistons.

 

about how big a dish?

would that weaken the piston if you made them very deep?


what about shorter rods..... is that even possible?

 

Why not just hog out the chambers?

 

would i lose alot of flow?

 

We did a C5R headed motor, with an F1 recently. Just opened the chambers to 48cc, and went with some big dished pistons. End compression was right at 9.7:1.

 

how were the results?

 

Honestly I think you are wasting time and money going with c5-r heads for FI. Why not just go with some all-pro or AFR. They may even perform better because you will be able to run lower compression.

 

definately not wasting money here... i have got a very good deal on alot of C5r stuff and it will not be wasted... i might just go high CR and 200-300 DP

 

Results were pretty good. We made around 680 I believe with 4.8 psi. We will be pullying up soon.

 

I see. If I were you and you don't mind nitrous, I would definatly run high cr and a lot of nitrous. Personally I don't like nitrous so I wouldn't do it.

 

LOnSLO is that a typo? 4.8 psi and 680 hp. I think that 14.8 psi is a little high forthat hp level also so i am lost.

if it's 4.8 I'm impressed

 

that aint no **** if its only 5 psi for sure

 

Yes that's 4.8 psi. This has a custom manifold, good sized solid roller cam, on a big inch motor. C5R heads are no joke.

 

holy ****!



how high did you rev the motor... and is this a sheet metal manifold? what was the lift and duration on the cam..... what do you consider big? 427?

 

tell me your lying

 

Who knows what the specs are. good sized solid roller can be anything, as well as big inch motor.

 

Sorry, can't give out specs. It's a customers car, and when they spend a lot of money, they don't want their combos broadcast. Just know it works

 

just tell me this what intake was used? who made it?

was it a supercharger?
