Looking forward to your report!

I'd like to shave at least 1/2 sec. off; though my wheel/tires aren't optimal for best times.
I just want to see how it runs as is vs. the base wheel's & then looking to get a lighter set of wheels/tires for the dragstrip only.

Looking forward to seeing this happen.

Thats awesome!

What tires did you use for these runs?

Was the car on E85 for the day, did you dyno these mods?

The tires used were Mickey Thompson E/T street radials on 300zx rims!
The car dynod at 308hp with these mods a few weeks after this was ran.
And negative, 93 Octane was used.

i have the first set of cams JWT came out with.
i don't think the C2 cams are out to the general public yet?

Interesting, would have thought it would make more power than that based on your 1/4 mile time.

But, that may have been a stingy dyno too...

not at all!
intakes, tear pipes, and CBE usually make around that power?

Yes, 306 hp is in-line for the mods you had at the time. BUT if your car weighs 3400 lbs and makes 306 WHP - it would normally run about 13.00 sec 1/4 at 104 mph in decent conditions.

BUT, your car actually ran 12.66 @ 3400 lbs at a strong 110 mph which is more like 330 WHP in my opinion (and according to most drag calculators like quarter jr).

So, I think it ran better than expected at the track! Maybe it had a really good driver mod?

Have you dyno'd it since adding the cams, port work, headers, 3" intake etc..?

Should really haul now..

aireoh · 01-06-2018, 09:35 PM

makes sense. i had been trying for some time to get a sub 13.00 pass.

and no, i haven’t Dyno’d it recently yet. i was going to this weekend, but i’m having some real major issues.
check out my other thread i just started about my car problems.

Lotta things come into play on a good 1/4 pass; as I only made 271/275whp on 4/5th gear on Dynojet-3days after going 13.1@104.89

As did mine..

Mine went 13.19 with 272 whp and 225 ft-lbs on a dynojet.

30 hp more would have gotten me to 12.80s in perfect conditions.

jchammond · 01-20-2018, 09:29 PM

Carolina Dragway Tomorrow...Pending No Work-Related Roadcall;
1-5pm.
Gonna make a few passes before any more mods/got the worn out 345/30's strapped on the back & still hoping for 12.70's or quicker,,,but you never know.
