N/A na6 quarter
 

Just thought I may aswell put something up. I had a mate going to the track today so I tagged along and took mine for a run.

Anyways it ran a 15.509 quarter at 85.24 mph, I had a couple more runs but boggd one and spun first the other but both had better mph, 89.32 and 89.41. I might see if i can scan the sheet in sometime.

Its a 1600 with 265deg cams, 2.5" exhaust with dodgy ebay headers, 4:3 torsen and 6speed box. Engine is unopened except for cams and is up to 225000km (about 140K miles)

It ran 16.7 stocker with just exhaust and cai so I am pretty happy with the improvements so far, I just can't wait to get the hairdrier on it now. Hopefully it shouldn't be more than a few months away when I can get around to making a manifold and get a cooler etc.

maybe try megasquirt, i think with flat shift, launch control, and tuning you've got 14s

Not bad for n/a.

Yes that is with all of the above. I only got 3 runs in so I didn't get a real good launch but the first wasnt too bad apart from heaps of wheel hop. I think there may still be a little in it but not 14's IMO.

Considering it ran 16.7 before and I havn't done much for power yet I dont think it ran too bad.

P.S. I only realised after I prob should have put this in the DIY section, it was so late the other night when I put it here.:)

That makes me sad. becuase i hit 15.4 (check sig) and i have a turbo. But thats a good time for N/A

oops didn't realize you already have all that. but still, your best run was at 85mph and you've trapped 89, which should get you close

Interesting to note Mach, I guess there must be a little more in it if the best time still had a lower trap speed.

Another interesing note was the 2 runs with higher trap speed were when I bogged(after I short shifted to secnd to stop the spinning) so if I could avoid the wheel hop at the start I might get a little better. I didn't think of it at the time, but my KYBs are on full soft, maybe if I tried stiffening them a little to dampen the spring oscillations it may help?

thats pretty fast for a na6 naturally aspirated

/me wants to get cams now

which cams did you use? im drooling to get some obx 264 degrees cams now :)

They are from a company here in Australia called Crow Cams. I don't know the full details of them since I picked them up second hand and havn't got around to calling crow for the full grind specs, but they are 265 degree in and ex.

The only problem I have had with them is that I have found it imposible to get the car to idle. Aswell as the cams I have an NB inlet mani and iac which seems a real bitch to control. Even on steady DC(warmup only mode) I have to have it idling around 1500-2000 rpm to stop it from huntung, thats with a pretty consistant 13:1 afr and flat spark table all around idle.

Nice times man. Thats two tenths faster than I ran when modded non turbo on a 1.8.
