I went to the drags (New England Dragway in Epping NH) last Friday night with my buddy/arch-rival from COMSCC (road course time-trialling club). He's got a 260fwhp 2240 lb. Omni GLH-S. On my first ever run down a drag strip, I did a 13.519 @ 106.49! To beat his 14.097 @ 108.77. Needless to say, he was having trouble putting his power down:) My subsequent runs were quite a bit slower, as I was having fuel pressure issues (clogged filter). We lined up four times, and I won the first two and lost runs 3 and 4 (run 3 by .03 sec, and with a quicker ET). My last two runs were right at 100mph, so I think I was fuel-starved.

Really pleased with that first run, though!

not bad...

so ur in the 13's with a stock L6?

4-speed or 5-speed tranny?

Stock differential?

Not bad at all.. I want

damn automatic

Nobody's gonna get a Z into the 13s with a stock L6! The motor is far from stock, it's a 3.1 liter with 11:1 CR, ported head with .550"/305deg cam, and 3x2 45mm carbs. Tranny is an '84 truck 5-speed, diff is a 3.70LSD from an 87 300ZX turbo.

Dan what engine head and cam are you using?

Curious because I have the option of using an E88 or P90 and have seen what a mates P90 engine can do.

My E88 has had larger valves installed and slightly lumpy cam with some porting etc.. it goes alright probably 14.5 down the 1/4 and trying to decide if I should start from scratch with a p90 or do more work to the E88 .

The head is an N42 (280Z square port). Sunbelt in Atlanta Georgia USA ported the head and did a custom cam setup on it. The cam is designed to work with lighter-than stock valve springs. This alone is supposedly worth 11 lb-ft (IIRC).

The torque dip at 4200 was accompanied by a very rich condition, but only right around that rpm.

I think you could use either the E88 or the P90, but the P90 will have to be shaved on the order of .080" to get a decent compression ratio.

That's an AWESOME time, you should be so proud... :classic:

oh.. oops..

i mistaked N/A with stock...
