I hear you. I really need a full cage, and want one for my safety! Then I could run at some better tracks. I would LOVE to run at Rt.66. This winter I will finish the cage. I also want to get my license. Your doing it the right way, smart!

 

Its a pain in the *** lol, I added almost 150lbs between the cage, battery in the back, ultrabell etc and was a ton of work and $$ to slow the car down a little lol. I installed the cage myself (wolfe 10pt CM) and I wont be doing that again soon

 

Nice runs in the heat Kev!!! I like seeing your dyno numbers because they are thru a non lockup tranny. It just goes to show how JUST the dyno number doesnt tell the whole story. Adding weight sux....I still wonder how my raceweight ever got UP to 3825 (i'm 200#) How much timing do you pull for the heat 90+ degrees vs say 60-70?

 

I just start pulling some timing through the IAT tables starting at 120. When its that hot the car isnt making a ton of power and I am running decent fuel so only one or two degrees get pulled. I am only running like 16-17 degrees anyhow so I'm pretty safe with the a/f around 11.5 in the heat. When it cools off and makes some decent power is when I have to worry about detonation but I run this very safe, i'd rather run OK and race the car all year then try to blow it up chasing a tenth of a second, no matter what I do someone will always be faster.

Thats why I spent a lot of time getting the 60' down in the heat this year, dont have to beat on the engine any harder at all and the car still runs quick. Cant wait to see what happens when the thing pics up 100hp on a 55 degree evening

 

If you dont mind sharing, what suspension and wheel and tire combo are you running?? I've go the power to get a nice timeslip but getting it to hook is going to be my problem

 

I'm running bogart 15x9.75 wheels with 10.5x28x15S ET drags @ 15psi hot, CE 3 way adjustable rear shocks set on 40/60, Spohn drag sway bar, stock rear springs, LCAs in lowest hole in relocation brackets. Random tech torque arm with a BMR TH400/torque arm relocation crossmember, -2 pinion angle. Strange single adjustable front shocks set four clicks from full counterclockwise with 275lb/in hypercoil springs.

Thats about everything..

 

Thanks...seems like you kept it pretty simple but apparently it works well. I was looking at the CE shocks as an alternative to the DA Koni's but havent heard much about them

 

They are cheap and they work, I am really getting to the point where I should go to some better parts but sometimes you dont fix what isnt broke. I still have power steering and stock front lower control arms lol. The track I was running at was prepped perfect but a couple weeks ago at another track on import day I was still pulling 1.31x 60 foots off the footbrake. I think thats the best its going to get at this weight/power level, cooler weather used to pick up my 60's quite a bit so I'm curious to see what will happen in a few weeks when it cools of some.

 

"-2 pinion angle."

That's the toughest one for me to figure out. I'm at +1 with stock radials. Put on the Bogarts and I'm at -2 without touching anything....pinion angle relative to a horizontal line is a crazy concept.

 

Man can't wait to see what it does when the temps drop

 

OK I'l clarify, -2 DRIVELINE angle. The car can be on its roof and it still measures the same All I'm worried about is the CL of the trans and rear being parallel under power to use the least amount of power and cause the least amount of stress. I let the chassis 'experts' argue about how it effects traction relative to the angle of the car

read through this, I dont agree with using the driveshaft method of setting driveline angle that some recommend but for the most part that article is OK. IMO thats why a lot of people tear **** out of the bottom of thier car, they measure off the driveshaft and end up with some funky driveline angles..

 

THANK YOU!!!!

I tried to say this and got flamed for questioning the gurus. I find it funny that these guys seem to think rear tire height affects how thier suspension is adjusted. If you're going to measure pinion angle like that then your pinion angle doesn't matter.

 

awesome kp, congrats on the bad *** 60's

 

Link is not working can you fix it please.

 

Great times, kp! I'd love to see your car run...

Jim

 

Thanks, 77 degrees for a high on Friday - may finally see a 5 second 1/8 mile pass. I swear if it runs another 6.02 I'm parting the car out lol.

 

you need to come down to brainerd on a friday or tuesday night

 

brainard is an OK track but crossville is 50 miles closer

 

What two points due you use to set up your driveline angle??

 

The trans output shaft and pinion. For example, most of these cars point the rear of the trans down 1-2 degrees, then the pinion at zero degrees (relative to the output shaft of the trans) is correct.
