4DF, any changes to your tires PSI before launch?

 

I just ran the OEM 32psi

 

do you have an idea on which ported mani your going with? If not I know I local guy that has proven dyno results and his mani is cheaper than z1, motordyne.

 

Doing it myself. I have ported a few Honda and off-road vehicles in the past so I'm sure I can tackle this fine. I don't go too aggressive I just smooth the flow and taper the lower runners to increase velocity

 

picked up some race gas anybody ever tried running race gas before

 

Report back asap

 

so bad news yesterday was the last track of the season and it rained so i wont know if the race gas makes an improvement until next year now

 

Bummer! Sorry it didn't work out. I'm curious: does the ECU need to be tuned (i.e. have a specific map) to be able to benefit from race gas? If not, I'd consider getting some for IFO at the end of the month. My tune is for 91 octane currently and I do not have any alternate maps.

 

ull need a tune for race gas i was planning to mix it with 92 octane to get me about 100 octane. seb gave me a race gas map i have 5 maps

1st is daily driving map
2nd is 94 octane racing map
3rd is race gas 100 octane map
4th is the same as second one but i can do standing burnout and brake torque to launch
5th is just valet mode

 

After seeing this, I’m going to be pissed if I’m not running 12s lol... love the car but damn man.

 

There's a guy with a rear mount turbo running 11.20's..

 

what kind of mods u got it also depends on track elevation my track is pretty close to sealevel and my best 13.1

 

Its full bolt on. Got 3 races last Friday.
Sadly, was only able to get a 13.31 @ 105.43.

Now for the Excuses
First time ever to track. On all season tires and 1/2 tank. If only I could brake boost to 3k. I feel like it would get much better 60ft. Also have a retune upcoming with all the change in mods since last tune. So car definitely ran consistently, I just need to practice the launch. All races were in manual , brake boosting to whatever it could, and shifting at 7800. Wondering what it would of been in just d. Car needs a retune to really wake up the car. It put down 321/264 at z1 with way less mods and than I ran for these runs. Car weighed 3750 lbs with 1/2 tank for these runs. Really need to practice launch. Also around 55-60 degrees outside.

 

 

Left lane. Elevation is 1,145 ft. Temp was high 60s. Need to improve that 60-ft time.



Comparing May (just Invidia catback exhaust) vs. Dec (aFe drop in filters, HPS intake tubes, FI RHFCs, Invidia catback exhaust, and UpRev tune)
