i went to sac the other night and i got a best of a 12.8@105.4 on my last run. how did i do?

60: 1.787
330: 5.259
1/8 ET: 8.188
1/8 Trap: 83.704
1000: 10.712
1/4 ET: 12.854
1/4 Trap: 105.481

03, stock 9.8hs, 91 pump gas, Stock clutch, 41k miles, stock 03 DV
264/272 cams, no cam gears, FP, drop in, TBE, FMIC LICP, hasn't been tuned for the cams yet.

i know there is alot more power once i get it tuned, cuz my traps are very low

 

Get a tune for the cams so you can trap a lot closer to 112. Test pipe or HFC?

 

what boost?

 

21psi, and its a TP

 

The car is just very weak, but the driving is good.

 

thanks, with a good tune it should gane back some lost power... i hope.

there was another blue evo there and he ran a 13.0@ 108 he had the same mods

 

The tune won't matter unless the current tune is terrible. Cams make power even without a retune, so you can't expect to gain much with a retune. The retune is just for optimization of the cams at idle and WOT, but it won't be a big difference in power.

 

I had similar results last night. I wasn't too happy.

R/T: .771
60: 1.811
330: 5.390
1/8 ET: 8.351
1/8 Trap: 83.93
1000: 10.935
1/4 ET: 13.112
1/4 Trap: 103.90

I've got 03, 9.8hs, 93 pump gas, Stock clutch, 32k miles, stock 03 DV
272/272 cams, no cam gears, Dynoflash, TBE, and I only ran 19 psi.

I was thinking I may go with a custom Dyno tune now. But, if it isn't necessary, am I stuck with these type of times?

 

Well, why do you have 272 cams without having all the other stg1 mods? Your mod combo is not wise. You should have a fuel pump, mbc @ 22psi, bov, and probably a good clutch.

 

2 give u guys an example, i ran 12.72 @ 107.89 on a slipping clutch (it finally went) with no cams.

when u r ready to get those cars tuned, put some cam gears on b4hand.

the only mods i have are: walbro, 3"TBE, hallman MBC, turboXS RFL BOV, 10.5 hotside, 104octane Sunoco GT Plus, & ECUFlash test mule tune.

the cams will make addl power once tuned but gains will be low on pumpgas especially 91 since the ECU will retard timing. the most u might get on the cam gears is -1/-1 settings to prevent knock. it will feel stronger in the midrange. a buddy i have in AZ ran a 12.49 @ 113 on his '05 with the same mods i have above except he has a 9 turbo & hard pipe kit

 

It was great seeing all of the Evo's at Sac Raceway last Wednesday night. I'm really disappointed with my times. My best of the night was a 12.1@112mph with a 1.71 60ft. This was done with a drop in, mbc @ 24psi, l.i.c.p., o2, tbe, cosworth cams, fuel pump, 720 injectors and a tune that made 306whp/304wtq.

My previous best was 12.1@114.9mph with a 1.73 60ft and this was before cams, l.i.c.p., o2 and a new dyno tune. The d/a this night was -1000 and Wednesday night's d/a was near 0.

I blew a l.i.c.p. off a couple of weeks ago and ever since then my car has felt down on power. I need to get it back onto a dyno...

 

Oops, forgot to mention the Wally 255 lph, Forge BOV (recirc), HKS suction intake, DP, and TP. The tune is safe to 22 psi on 93, but I have the Greddy Profec B spec II EBC. Haven't messed with it too much yet. About the clutch, I plan on using the ACT HDSS with lightweight flywheel soon.
