Mr.Big

We replaced the headers and exhaust we already had on the car, with even larger units 2in primaries+3in exhaust, and we made some modifications to the methanol system, needless to say I'm very happy with the results...





I know this one is cheesey but what the heck the setup made it so why not... UNCORRECTED numbers!!!

You're going to have even more fun with it this Season! Bob

Mr.Big

Thanks guys, I'm just happy to see the broad power band with the little 370c.i.
The 317's are my current bottleneck so hopefully new heads before Spring...

Great numbers man ...
Still 20lbs?

Whats the engine compression??
We need some vids

Mr.Big

10 rib with a D.P. "direct drive" conversion ZERO slip street or track...
only pic I have to offer for now, this was during the build, I'll post some better shots when I get home.



24psi and 9:1 compression, I'll be home soon to drive it, hope to have a video of the fun soon!!!

Thanks guys!!!

Do you have any pics or other info on the drive set-up? Costs, parts location, etc.

Looking to use an F1R in another body platform and am limited on supercharger mounting places. The Vette set-up puts the s/c where it fits. Only accessories would be w.p. and alt.

PM is fine if you would like.

Nice power, impressive! 24 lbs 4bolt stock heads, do you still run the Vette stock intercooler with the E85 set up? What lb/hr injectors are you at?

Love the car and the torque curve call me crazy but shouldn't a F1R at 24psi be well over 1000rwhp corrected?

P.M. returned but this wasn't in the P.M.
I run the high Z ID2000's they are the best injector I've ever run, I can't say enough about the quality of the product, the data shared, and the drivability, You'd never know they are capable or 300lb/hr... though I only run them at 58psi... They are pricey but they are worth EVERY penny...

Keep me posted on your build, sounds like a VERY neat street rod...

Mr.Big

The bottle neck causing the 24psi are the 317 heads and the small 370c.i. engine... If this were a 427 with decent heads, or hell even just decent heads it'd be more like 20psi or 18psi with larger c.i.

We didn't push any water the first time at the track, but we also broke the drive shaft guibo on the third pass... So time will tell, but I have a line on some killer heads so hopefully we'll be making even more power at less boost due to less back pressure soon...

Just curious, what are your injector duty cycles at this power level with those sweet injectors, also what fuel pump/s are you running ?

Mr.Big

71% IIRC, and the Largest Magnafuel pump that they offer, I'll have to check later for the exact model number...

I saw the new numbers in your sig. Congrats on the monster setup. Do you think the driveline is going to live up to the new power?

Impressive, especially with the 317's. Bring it to TX2K11!

Mr.Big

If I can make it again this year I sure will... We had a blast down at 2K10 in Mexico...
