Let me reserve judgement on this til tomorrow. Just swapped in the stock TC - so far not noticing any difference. The reason I was highly suspecting the TC is becaue mine was done slightly differently than all of yours (assuming you went/going to go with Edge Converters); they just modified the stator and not the vanes. He told me that this may be hurting the "top end" , whatever that means.

I may have wasted $350 today, but I will do some runs later tonight for good comparison with my previous runs.

Thanks buddy

That means a lot coming from you, i'm glad you liked the car. As I said just above, I hope i get slightly better numbers tonight when i do some runs, or I'm gonna be upset. I hope ther ewas some power in the TC. If not, than I am truly perplexed as to why my car was not making much power pre-TT.

The only way to know for sure is to dyno..but it feels execptionally strong and responsive. I think my plugs are fouled becuase mine is starting to run a bit rough....

 

Great to see some comparison and analysis GQ.

 

Hey Guys

Did some Gtech runs last night after I found an exceptionally straight, smooth, and level road. Did a new bes tfor this car in the 1/4 mile. I would appreciate any comments/suggestions that you may have for improving them.

Conditions: 12:00am-1:30am; 60-62 degF; tank ~ half full (~10gal)
Boost: ~4.3psi (0.5bar)
A/F ratio: 13.4-13.0 (2000-4700rpm) and 11.5-11.1 (4700-7000rpm).

Best Run (moderate brake torqueing):
1/4mi: 13.196 sec @106.00
60': 2.109
0-60: 4.996
0-100: 11.927

Another run (moderate brake torqueing):
1/4mi: 13.257 sec @106.49
60': 2.152
0-60: 5.091
0-100: 11.852

Another run (no brake torqueing):
1/4mi: 13.328 sec @104.73
60': 2.146
0-60: 5.133
0-100: 12.441

Slowest run (NO brake torqueing):
1/4mi: 13.426 sec @104.08
60': 2.093
0-60: 5.261
0-100: 12.639

Obviously a good launch means everything. And really cannot launch at anything over ~2200 rpm as I just burn out the tires through the rpm band. I belive that with wider/better tires, better times are to be had at this same boost level.

I was a little worried about the lean a/f and it's drastic drop at 4700rpm, but not too worried as my timing is retarded 4-8 degrees. I took care of that issue this afternoon with a reflash (the a/f, the timing was left untouched - still wanna be a little safe).

Thanks
Gurgen

 

Great runs only thing from your post and i'm being nit picky but 4.3 psi is about 0.29 bar you have 0.5 bar which is closer to 7.25 psi. It's late but I know what you mean. 4.3 psi since the spring on the PE wastegates are set to 4.3 I think.

 

yeah sorry about that
l i meant to say 0.3 bar
made the same error on g35driver since i cut and pasted from here!
