Did you already order the SRT dual pump hanger? Its likely that will take a month.

what happaned ? why you are not satisfied? i know the jo say the he was shotting for 500 on pump.. so what he say about only making 344hp?

have not yet ordered it, but maybe picking one up used.

I was expecting at least into the 400's Idk but im not sure how far advanced they put it, i know my boy is running 22 Degrees on a stock car so i should be above this but i know CMB went rather conservative on the tune because he does not know the limits of the car no wants to be held responsible. I respect his decision so just looking to switch to E85, dual pumps, and a 4 port solenoid and see if i get it to where i want it.

First things first, what injectors are you running? I definitely believe you need a second pump, you're running a walbro 255 right? Dual hanger will be a nice upgrade, and I'm with CMB i'd be careful too. E85 should definitely break into the low 400's at that boost level. Have you asked Vit what he thinks?

I've asked some tuners who have experience tuning the r18 and they run 22 advance for fuel on stock block and I believe CMB is running under 18 so there's still more to pull out of the car I believe. Also 1000cc injectors and going for dual DW300 since two 400s don't fit. Also CMB said easily over 450s low 500 on race gas and low 500-600 (whatever the turbo maxes out at) on C85(improved version of E85)

If you want to make the most power possible use vp import 120. It's 120+ octane racing fuel. Guy on 8th made 600 on stock block k20 and a gt35 with that stuff.

VP c85 is better.

Just takes more gas than you would with race fuel

[aLmk]

If you think so, its only rated at 90 octane.

[420Coupe]

You can dump more of c85 and keep pulling ignition unlike race gas, you have to mix methanol with race gas to be able to pull as much timing. All you need is supporting fuel mods ie bigger injectors 2150 FIC, 2x DW300 and -8 AN feed

Theres no way anyone is running 22 degrees of timing on a stock block unless the'yre making like 3psi. What fuel? What setup?
