Un-tuned with cams and fuel pump

Well went to the track on sunday and am just posting the results now. It was my 2nd time to the track EVER and first time since cams. The track was Great Lakes Dragaway in Union Grove Wisconsin. The temp was around 50 and low humidity. Anyway my mods include Buschur Racing's Stage 2 along with Ebay O2 housing, Horsepowerfreaks LICP, GSC 272/264, and Walbro Fuel pump. The car had a mail in flash for just the stage 2 but not the other mods. I was peaking 22.5 and holding about 20.5 by the end of 4th gear. Launched from the 5800 rev limiter, I was having a little bit of a 2-3 shift problem but NLTS the 3-4. I will be getting a custom AMS tune next tuesday and Exedy HD twin ceramitalic in december. Do you think I am capable of 11's on pump?

Best run:

r/t .436
60' 1.750
330 5.158
1/8 7.978
mph 87.65
1000 10.377
1/4 12.38
mph 113.06

Not a bad trap for being untuned, I wonder how lean its getting though with the addition of the cams...

Doubtful on pump unless you gain a lot of power with the retune, which is not likely.

I would say you will run under 12.20 for sure. And you can still knock down that 60' time with practice. It is not easy though. I would have to say good job for your 2nd time EVER at a track. Good work

I should get a decent amount of power out of the tune. Also this run was with a passenger in the car and a full dual 12" sub set up in the trunk. With the subs and passenger out, not to mention the tune and clutch, I should be able to get at least another 2mph out of the trap. People have run high 11's with 115 traps

with a retune and a better 60 ft you should hit 11's.

Hell with a 1.6 60 foot you would be knocking on the door of 11's as it sits. Every .10 gained in the 60 foot is good for .2 up top.

Not really. You dont automatically gain double like that. That ratio lessens when in the 1.7 range already.

No need to roll your eyes. I agree that 115mph traps are easy 11s. In fact, it takes poor driving to NOT hit 11s with 115 traps, and your driving does not look poor. You also didn't say anything abouthaving a passenger and extra weight - not sure why you'd do that if you were trying to get good times at the track - it makes no sense. I can't guess that you had a passenger and extra weight - you have to mention it. What I said was that I don't think a retune will gain that much extra power, and the clutch certainly won't add to your trap speed. Generally, if you cut a better 60', your trap speed will go down slightly.

If you do indeed gain 20whp from the retune (not normal), then I think you will be able to hit 11s on pump gas.

11s on pump are achievable with those mods... There have been several locals here that have hit 11s on pump and they have been 03s with still having a 9.8 hotside...

Sorry, looking back on my post the rolling eyes was a little uncalled for. I had a passenger and the extra weight just simply due to that I am very very new to drag racing in terms of being a driver. I wasnt expecting the results I got running untuned. If I had known that I could be knocking on the door of 11's I probably would have kicked the passenger to the curb along with all the stereo equipment
The clutch should help on my 60' along with losing less time on shifts. 20whp out of a tune doesnt seem too out of the question, its running pig rich due to the fuel pump currently.

Hell, if I cant break into 11's on pump, it should be EASILY achievable on some race gas and the boost cranked up

The fuel pump can't make it run pig rich itself - just a little bit more rich than before. A tune from stock will show 20whp, but rarely do you see that much gain going from one tune to the next even with a change in mods. It may happen, but I just err on the side of caution when it comes to power gains. People almost always set their expectations too high. The clutch should help the 60' a little, but not the shifting.

Yes, easily on race gas - no question.

You dont think an Exedy HD Twin will help with the shifting at all? People always talk about how those things thrive on NLTS on every gear change. I only NLTS the 3-4 on my best run. Also the tune is coming up this tuesday at AMS so ill make sure to post the before and after dyno graphs

I don't know - that depends on you. I didn't have any problem shifting fast with my stock clutch, but I do think I got a little faster with my Exedy 4-puck. My gains were related to the nastiness with which I shift, but not everyone drives like that, which is why I said it depends on you.

Those are some nice times, but how in the heck were you able to run those times with a passenger in your car? Every dragstrip I've been to will not allow a passenger if you run 13.99 or quicker.
