KPM has a chart for gasoline and E85 and forced induction.
Basically an E85 car with forced induction that is 1000 hp needs a step up in the kit.
The ratings are for naturally aspirated on gasoline.
I bet you could inquire directly with them about your fuel and psi and horsepower and get a...
:crackup: Amazing that the torque curve is still climbing up to 7,500 rpm! (oh, on second review, it's only 7,450 rpm)
Also, this was not E85. It was only E30.
Seriously, I wonder how long that thing would live at 8,000 rpm and over 1,000 horsepower. That is a lot of rpm in addition to the...
For whatever it is worth, I am running PS4S 305/30R19 on 10.5" OEM wheels with no issues. I am just commenting that they are a different size from the same supposed size in Pirelli Trofeo RS (front and rear).
Where does the fuel go?
When I open the fuel filler door and place the nozzle in and start pumping fuel, it goes down a tube of some sort, to where on this picture?
I do not know if there are any other physical difference between your car and my car in terms of the fenders or fender wells - for instance, the driver side has slots in the fender well to let air out from the oil cooler, which is installed ahead of the tire. If you have the performance package...
That sounds not far off from the Dark Horse wheels width and backspacing.
The front fender arch is not a necessity but maybe will keep it from looking like it sticks out. I doubt the adjustable camber plates are necessary, either, as my Dark Horse has a street alignment.
Tires matter a...
First, I have no idea if they really are given a hardening treatment, but, IF they are, then the reason is not a shift RPM difference, but the likelihood that the Dark Horse will spend more time up there at or near the shift RPM, which would be the same reasoning for change to the connecting...
Have you given any consideration to stiffer front springs, e.g., the AJ Hartman Aero Magneride coilover conversion springs? I think your springs are at about 211 (going off memory) and his springs for from 300 to 400 lb/in with 5 different options. Just a suggestion.
The stock springs are...
