Those were not too bad. When you break the converter, pinion and all the baffels in the pan, thats tire shake.

Hey Joe! IMO- Bias 50 min. Radials become very unstable at 60 to the point that the actually bang while hook and spin. Last week we ran radials and at 135 deg track and our 60 foot only varied 7 thou from 89 in the morning. Two months prior in Sacramento temps were 138+ and we were wheels up no Prob...

They work perfect. Too bad NHRA will not let us use them.

Q 16 is well worth the investment. 637 cu inch DRCE2 , 2420 lb door car, 7.13 @ 196 with C25. Changed to Q 16, jetted up, air was 300 ft worse, 7.05 @ 198. Jetted up again in 400 ft worse air, 6.96 @ 198 and change. I would say it's a little better than 20 hp. At least with our stuff. Yes the EGT's ...

A 10.5W measures what width? 12? I used to run a 14x32W Firestone #9 on a 12 inch rim at 6 lbs also with a 4.30 gear. Went 7200 in the traps @ 8.80. 1650 lbs LT1 350 no tricks. 1978.....

Do you have a wheelie bar? If so lower it. More than likely you are rebounding the tire. Lower the bars and tire pressure. A FED/Alt does not like a high wheelie bar.

JB, build yourself a blinder and leave off the bottom bulb. It makes it a .500 pro tree. Use the stock visor modified or build your own. You will want to back light the reverse side of the blinder at night with an amber 194 bulb. That takes away the glare of the previous yellow coming down at night...

Merry Christmas and Happy New Year Mike. Been a while since Jeff and I saw you a while back at the Autolites. Sounds like all is well up North. I will send you a pm.

Going from a 4.56 to a 4.30... My opinion... You definatly need a 1.90.

How much torque do you make? Our 560 has 825@ 7300 and our 602 has 935@7400. Unassisted. The 1.80 killed between .05 and .07. We ran a 1.90 before and it loved it. We are at 2300lbs and the 560 runs 7.20's @ 190+ with a 1.04 60 ft and a 16x33 Goodyear Pro Tire. Only shake down runs thusfar with the ...

From what I have learned...... It looks like it wants more low gear. Is that a 1.80? If so a 1.90 would pick it up .05. You might try to loosen the shock compression setting also.




BP

Who's shocks and what is the rebound and compression set at? Looks like your wing is working by the compression. Looking at you ds, the track was not that good, spin, hook, spin and...... You can see that in the G meter also. It looks like a ton of movement but it is not. We go full soft 2.5 into th...

Late model Impala/Camaro 12 v air pump. Build a good oil trap/ filter. The vanes deteriorate with oil. Most likely at any salvage yard.

Mike. Anything for the Isuzu Diesels? 03 Chev dually perhaps? Average combined now is 15-17 and 20 highway @ 68mph.


Thanks.
Barry

Kevin and Sammi are the best out there hands down. The best kept secret too! Thanks for your quality work and time.
