How'd you launch it? I can't get under 1.9 for my 60ft... Most of the time I launch 1500-2300.
I go around the water box, back up in front of the water. Boost launch around 2k, prestage, another 2k launch when light goes green. This time I didn't have an air gage, so I counted to 10 while letting air out on each tire. If I had to guess it would have been mid 20's psi...TopherSho said:f8tlSHO said:E30 ajp tune 14psi, 3 bar map, k&n drop in filter. Full weight including 2 child seats. 65-70 degrees, 975 DA.

ah well, I need downpipes to get better 60's then. It has to be spool rate after a 2k launch. PIR is 50 feet, woodburn is 194 feet.

This was a 19xxrpm launch.
140-IAT2.
92 octane pump gas.
4650lbs car weight with me in it.
no hop, no spin. *20 inch tires* .. I am starting to think the custom rims that came with the car are hurting launch rotational mass. Also i do not race prep yet, I had 37-pounds fronts and 45 pounds in back since the tires do not spin.

92 octane..... that's your problem... I'm running around 97 with the e30.. who is doing your tune? All those other variables look good. More octane = more advanced timingTopherSho said:PIR is 50 feet, woodburn is 194 feet.

Ok it is a launch Torque thing. My tune is from his-Brad-Ness
. i have a 14-lbs tune to install and test, the last tune was 14.5 and was *slightly* better than the 15-lb tune i ran 0n the 2nd of May. May 2nd i ran a 13.09 with 92, with a DA of like 34..
This was a DA of 1452 and was faster by a tiny tiny bit.
13.09 on 92 octane with that 60ft sounds correct. I am running major timing advance, but like I said the octane supports the extra timing. I have great gas in my area also.TopherSho said:f8tlSHO said:92 octane..... that's your problem... I'm running around 97 with the e30.. who is doing your tune? All those other variables look good.

I *will* break into ''printed on slip 12's'' eventually on a 'non-prep' car with just pump-92.
It is now my mission in life to do so.Joeyfuzz911

Anyone know what a stockish (intake, 3 bar, 170 testator, Corsa) sho on 93 octane and AJPturbos 17.5psi tune might get in the 1/4 mile? Has to be better than 12.9 @ 103 on my old Unleashed tune.
I'm thinking 12.7 because top end is much better than the Unleashed tune I ran at the track.

Hard to say, 17.5 psi creates more heat. That's why my tune is down at 14 with more timing with the e30. Easier on turbos, I like the power the timing makes better anyway. Hot weather does not seem to affect the car like it does with high boost tunes. This is by far my favorite tuneJoeyfuzz911 said:

I am a little Jealous, Good all the way around ;D
and U are making me want to Do 1/4 instead of 1/8

Mine doesn't create that much heat from higher boost. My 3rd gear hits 17.5 but tapers and holds strong at around 14-15psi. During datalogs, IAT2 was only 130 in 85 degree weather. Brad doesn't want to go higher to control my fuel pressure and because IAT2's that reach above 150 will mess with the spark. He explained in a much thorough way lol.
I'm thinking 12.6-12.7 range if I can get a good launch.
I guess I'll just have to go to the track and find out.
