so...news update
had a good long talk about this..
I am not alone, @
robispec has experienced the same issues, so its about carrying high G's thru a corner (he is way lower CG and I am way pushing my r-comps)and pulling fuel out of the bowl just afterwards of a high G event and going WOT-not pump limited, and thats why I have not put a aftermarket pump in, it will only make it worse.
Per Robi, he is about to put his OE pump back in, as it in fact does get worse with the higher flo pump...so that made me feel better about what I had been theorizing from my tests, and we have arrived at identical conclusions, him on NA e85 and me on FI pumpgas, so bigger pump is NOT the answer. Thats the problem rather.
While none of you will ever see this on the street, tho it is a very real issue for those who track it at the limit. As I expect the problem to be worse doing the 12psi testing I'm about to do, it makes me hesitate tracking the car that way, it makes me worry about lean----? leading to Kaboom! and so I think its good to know the track limits of the oe fuel setup,
and the risks goes up as boost goes up
Robi and I agree, the solution is out of the box, meaning the oe fuel tank and setup is where the problem lies, it was never made to do what we are asking it to do. This is gonna slow down my testing, since unlike many guys happy with a dyno chart and a few passed cars on the street, I'm not happy till this thing runs like a wristwatch out on the track
tentatively I'm firming up plans for a visit out to see Robispec to deal with the fuel issue as a priority, end of May is when I plan to be out there for car work. I'm looking at a custom fuel cell.alum solution from him, as its clear he's already ahead of me with recreating the problem and finding a solution, this will be a good, I'm looking fwd to working with Robispec.
If we can solve teh fuel issue, then it makes sense to continue to make it faster, both in corners and in straights, so that helps me continue on to adding better suspension parts-right now I'm fuel limited in corners when I am anything but full of fuel, so adding front control arms, be it Robi or racerx, will need to wait till I solve the fuel issue. If that goes well, I may be up for the robispec cooling kit too...
those of you who have no clue what this is, go spend a bunch of time on the track and you will see this thing rear its ugly head, its systemic, not build specific
I broke the dongle on my ecutek key while lapping, so theres a small gap but usually I am logging, I wasnt logging the fuel rail pressure value that day tho.. next weekend I have the opportunity to track but no dongle...so ... waiting on ecutek and @
PERRIN_Jeff to help me recover from that one
