Max boost

[01yellercobra]

Whats your fuel system? Almost maxed 1050's now I'm thinking I may need rails and injectors.

Twin 450's, -8 feed and return, and Fore rails. I had seen some people max out the 1050's when I bought mine, but I thought I'd be on 91 more often than I am now.

Almost same, looks like rails and possibly injectors in my future, I'd rather not raise pressure to compensate. So pumped for that 1st tank of corn! And Kevin's tune!!

I'm somewhere in the 700 range. If that helps. E85 is definitely addicting. My car is rarely on 91 anymore.

How much boost are you seeing with the 3.00 upper on a 2.9 whipple?

I'm at 25-26lbs with a Gen4 2.9 Whipple w/crusher inlet, stock motor, stock head studs, E85, 3.0 upper w/stock lower pulley combo, Kooks long tubes w/matching X. More than id like but I cant find 3.25 Reichard pulley to replace my 3.0.

I don’t beat on the car all that much, it’s just a cruiser for me. With the 3.25 whipple pulley it was around 22-23lbs which I liked better but the polished Reichard pulley looks so sweet at car shows!

Hate to say it but I have no idea how much boost it makes. I still have the same 15 psi overlay from my eaton days. But everything I’ve read, and these numbers vary greatly from car to car, is it probably spikes to 22~24 ish psi, but the standard inlets don’t make, and hold the boost like the crusher inlets.

I messaged you on IG.. I have a spare 3.25 RR that I bought a couple weeks ago.

I'm seeing 21-22 lbs.
