It was hard to get consistent E85/93 ratio. Seems 3.5 gallons is the sweet spot where pump is fine on stock fueling. I was trying to get the 93 before E85 but found I couldn't accurately gauge how much gas was in there and once we had issue with hpfp because the 3.5 gallons was like a gallon short of a full tank so it was probably more like E40. Pressure dropped to not bad but not super safe level but then recovered so I knew not to do that again. I just limp it back to the 93 station and it's fine running on E85 for a few miles.
Pretty much flatlined around 28psi give or take. Can probably run a taper and more boost but not worth chasing it and being concerned about fueling. ROI takes a huge dive if I need to dyno tune it and add fueling. Not worth it IMO.
I'm impressed that stock fueling is able to handle that much boost with e30. I have a lpfp and have to be under e40 or will see pressure drop. The pressure drop doesn't acutally show up on a single gear log but I see it in 1/4 mile pull so if you haven't done so do a 1-4th gear log to see how your fueling is doing.
Third doesn't have to be useless.
I'm running 245/40/17s...I specifically dropped to a 17" wheel to put more sidewall on the car to help it hook.
With Indy 500s (a decent tire, but nothing super sticky) I'm dead hooked in 3rd down to about 40 degrees, even on E30.
When first installed they would spin 3rd, but now that they're broken in they're working well.
Second spins but it's productive...it actually puts you in the seat while spinning.
I have same tires but not so great federal 595. 1, 2, and first part of 3rd is useless at full throttle but with throttle modulation is totally fine.
It's only worthless if you are on crappy allseasons and floor it. Your right foot can limit wheelspin and still be quite quick.
For sure. But when doing logs in 3rd you have to floor it. I had to start doing logs in 4th but that gets pretty sketchy. That's where drag radials will come in handy for 3rd gear logs again. But been too lazy to swap just for logs. LOL.
