This was the first race of the year at this track due to rain,so maybe that has something to do with it.My tune up may be off (too rich down low)this Friday i will do some testing. I just rotated the tires and treated them and i am adding 60 pounds to the rear. The reason i think i am losing et is the 1/8 mile et should be around 6.12 for am 9.67. I have got plenty of speed and a conservative tune up but i want it to hook consistantly or i will be a duck out of water.

Hmmm.... You're et.r the same as mine but at 137.My 1/8 mi et. is [Email]612@111[/Email] at 3350 on a 29.5 10.5 w so i think we r running identical times but u r losing down low.Care to share a little info on that combo?Oh..i 4got to mention that my 60's r 135 off the foot break with M/T slicks

Well,its a446 rb,bulldog heads 338 in @.600,14.7/1. 690/670 roller,2/1/8 hedders,53%/47weight at 3050. 4.56 gear 5000 stall ,off transbrake,these runs were leave at 3700,shift at 6500. trap rpm is 6500 at 138.Rons injection on methanol.I am not lacking for power,i am spinning into second gear.Car actually transfers weight and initial move is very good but then losses traction.The same chassis went 1.32 with only 550 hp. Shocks are new double adj.The suspension works better at 4200 leave and more et at 6800 shift but i want to solve the launch issue first.

Thaxx's 4 the info.I See that your heads flow better than mine with 338@600 I'm a set of the stock -1's with milled 4 more compression.Hopefully next year i can have them ported

Actually ,i bought this engine from a buddy that quit racing.The heads were ported by Hughes their stage 3 i think. They claim 348 @>700 but i would guess more like 325 max. Still plenty of power for what i want to do.I talked to a Goodyear engineer and he suggested their d1823, 31.5 14.5 4a compound.Hope to run tomorrow.

Hughes does a pretty good job on there porting had a set of 906's done about oh..15-20 years ago(still have them)ran pretty good 4 what they were on (446) Good luck with your tire selection

i made several test hits and fortunately a couple of well known chassis builders watched the car and helped with shock adj. and tire pressure.Went 1.37 ,1.36 and 1,35 60 ,9.74 best.My incrementals from 330 on are very good(330 to 660in 2.17and 660 to 1000 in 1.90 but i am .14 slow from 60 to 330.There consensus is get new tires with a softer compound and the converter is too tight.So i will order tires tomorrow and hit the national ope at sacramento in a couple of weeks.

Cool and Good luck
