Official "Pure" 91 octane evo thread
hx40 evo pump
This car is just insane in the build quality and the attention to detail. I was thoroughly impressed by the responsiveness of this turbo and the whole car. I don't understand why more people don't utilize these cheaper turbo options
this is 100% 91 octane and at 4800 ft above sea level in utah(slc) I was being conservative on his tune because he daily drives it and also track races too.
The car mod list to the best of my knowledge
2.3 stroker motor eagle rods. wiseco pistons
stock head
supertech springs
gsc s2 cams
880cc injectors
walbro 255 modded
jacks transmission trans and t case
EBB Fab top mount twinscroll kit
EBB Fab 3' aluminum intercooler piping
Holset hx-40 hybrid with borg warner compressor wheel
holset 12cm (.89 A/R housing t3)
twin mvs wastegates
ets garret core
stock intake manifold
stock tb
sparktech cop kit
stock 7 heat range plugs
this car has been lightend and had huge widebody kit and also on some knarly rpf-01 the weight is scaled weight with two people in the car and the pull was in third gear at 31psi tapering to 27 by redline
tires are 265/45/17

Race Gas Tune:
Q16 @38psi / 734 WHPS (we need bigger injectors for more boost)
With my mods, I was tuned on a mustang dyno 264whp and 282tq on 91 octane. When I was on 93 Octane my numbers were 334whp and 352tq (tuned by Mellon). Going from 93 to 91 octane I lost about 20% power. Is this normal?
91Octane fuel , I am in Az.
93 Octane, I was in Texas.
If this makes a difference.

I am waiting to recieve my CAMS (Backorder Sep time frame) to instal and re-tune.

TBE including 02 housing
Evo 9 Turbo
Walbro 255
ECU Boost Control
Tuned by me @ ~25psi (this was one of the earlier runs that I did so the boost is not as consistent in the midrange, but it is better now)

I think 342 is a little high because there is a little upward then downward slant at the end of my road that makes VD show less power (around 6,200), and then a little more at the end. I doubt I will keep the car at 25psi for long, though.

I read the sticky! Lol...I get consistent results, I have probably done over 100 pulls on this same road lol. While I was pretty much done tuning for 25psi, the VD always showed within 5 or so hp of 340, but does having a downhill at the end of the road I test on make VD think the car has more power than it actually does?

Yeah, thats what I figured. It makes sense on the graph too because the power dips slightly when i would be on the uphill and then rises slightly on the downhill. It's more noticeable with less smoothing too. Thanks!
just for fun, do a run downhill. the graph is awesome. LOL
