New best 1/4 trap speed, 1/8 ET and trap speed

[Falco]

Howdy,

I was racing last Sunday. Unfortunately I couldn't raise my personal bar 1/4 ET wise. However I could run my best 1/8 and best trap speeds. I had serious traction issues.

60' 1.73
1/8 7.284 @ 95.94 mph
1/4 11.420 @ 121.17 mph

This is still my street setup, 18" wheels, A048 Yokos, 21 psi on pump gas with methanol with ~19 degree of spark advance.

So far so good. We have one race left this year...

Later,

Thanks Phillip! I wish I could reproduce your short times. It would be a 10 sec truck now. Should replace these 18"'s with something smaller. That's the big dilema.... :lol:

Ed,

I'd go with 16" drag radials if I went back. M/T or BFG. I'd say 15" are not possible because of my Baers front and rear. However my bug is to produce the best number in street trim, which I could reproduce anytime when I put the pedal to the metal. So no race gas, no non-street legal tires etc. Also let's not forgett that we have no prepped tracks here. We are racing on airstrips or 1/4 mile cut outs from a circle tracks. No one is pulling below 1.6s here... Guys are going 150+ mph but still in the 1.7s...

Ed,

I can put back the stokish wheel in the front and measure for you if you like...

Thanks Tasos! 5700...

About the converter beeing loose. It's a raptor 9/12". The RPM never goes below 4000 during the run. However I've no problem with it in a traffic jam or going uphill with easy on the throttle...
