Because i tried with stage2+ and had higher time corrections compared to stage2..

Tonight i'll try stage2+ again and upload the log here

enemigo13 · 08-17-2023, 05:58 AM

add few liters of e85 and timing corrections will be gone. also if ambient temp is high (like +30C or smth) car will noticeably slower

E85 is not available in my area. I bought 50 liters of alcohol ethyl denatured 100°..I will try to add it to the tank and check the log

Measure the alcohol content yourself! Do not trust the label!! More often than not, it will be lower! 100% Ethanol requires additional destillation. So unless it had a corresponding price-tag, it is most likely around 96%.

If it says 100% 200 proof anhydrous ethanol for him, it should be good. If it’s been denatured to any degree, the specs must be observed. I’ve used pure 200 proof before and tested it myself.

RacerX85 · 08-17-2023, 05:32 PM

I bought directly from a company that produces alcohol. They have two versions of denatured ethyl alcohol, 94° and 100°. I bought the 100° version. this is the description:

"Completely denatured 100° ethyl alcohol following the legislation dictated by EU Reg. 1112/2017, it is colorless and odorless, ideal as a solvent in the restoration sector to dissolve shellac, or in the chemical-pharmaceutical sector for in vitro diagnostic use."

That‘s really fast! Do you maybe have a log?

Great numbers, impressive to see this being done with an older version of the Pure 800. What exhaust is on the build?

M Performance Exhaust + VRSF Downpipe. This numbers where done with unfinished map. Could not test final map, had no traction i limit 3rd gear torque. Lower temps would help even more

Nice, I used to have the exact same exhaust setup until I switch to a turndown. If you were to swap to a 3.5” diameter exhaust/downpipe you could probably cut a couple tenths off just by freeing up some back pressure and flow the turbo is seeing through the stock style exhaust/downpipe.

Yes might work as you say. Something that would also help is having a nozzle with water or meth spray just to get cooler IAT's. There are ways to improve this. First i need better tyres

For sure a water meth nozzle will help, on a stock intake manifold even more. The bigger exhaust is the most simple mod, but since your rwd on a narrow body tires are super necessary. My one issue with the F2X body is how narrow it is, it’s my one reason as to why these cars need to be x-drive.

Which HPFP do you use and I guess your torque is limited when still having the stock transmission, right?

Log is looking really good. What was your setup in detail?

DS2, but you perfectly can with a TUPump, PI is more than enough fuel for my setup. I limit torque in 3rd gear to decrease will spin, not because of trans limitations

That is crazy fast. 5.78 60-130 should equate to about a 140 mph trap!

And in the upper gears? 800nm limit or even more?

I have also 6th gear at 650ft-lbs but i almost never go thru that gear. 130mph / 200km/h is at 5th gear 6000-6500rpm. Then i just stop accelerating and change to 6th gear

Do you use drag mode in xhp?
