No 5 second pass yet- ran 2 6.20 passes, and one 6.70 pass (kicked the tires). The car is way easier to drive with the progressive nitrous controller- I used a .5 second ramp with 250hp jets, and it comes in hard enough to really help, but doesn’t upset the car as much as it did before. The track was really bad, everyone had a hard time. Whatever little rubber buildup we had going, is all gone from the 2 weeks of rain. 1st 6.20 pass hooked pretty hard in the right lane, but shot to the right, so I couldn’t spray it until the front tires came back down. If it went straight, very well may have been our 5 second pass. Ran the next pass against my friends Vega in the left lane, put some ladder bar preload in it, and left everything else the same. Smoked the tires- 1.88 60’. Pulled more timing on the launch ramp for the 3rd pass in the left lane, went right down nice and straight- 6.20@117. Might try and re-situate some stuff in the trunk to try and relocate some weight from ahead of the rear axle to further back. We’re probably putting the small tires back on for the rest of the season, got some new truck parts to try 😎.

Getting close- went out today, went 6.09@116 on 28x10.5s. 12 degree launch ramp for 0.8s and 250hp jets in the plates on at 0.8-1s with a 1s ramp time 😎. I think it would’ve taken a 10 degree launch ramp, but we ran out of time.

Nice! I might have asked before, but what wheels, width and backspacing?

They’re Sanders engineering on the back- 15x12 2” backspace. Really could use a set with 0” backspacing, but I think 1” is the lowest they go

 

[Pro Stock John]

i'm running their 15x12 1.5s and I recall Larry Hodge the dealer saying they could be bought on a 1.0 backspace.

 

[ReasoTreason]

I’m figuring we can save 20lbs in the exhaust. It’ll also allow us to takeout the 300lb G force trans crossmember and put a lightweight tubular straight one in.

I might reach out to Larry Hodge- we have a new set of 15x14s w/ 3.5” backspacing. I think we can turn them into 15x11.5s with 1” backspacing by swapping the rear shells to ones from a 15x12 with 1” backspacing. After yesterday, I don’t think we’re gonna put big tires back on. If we did, it’d be a 29x10.5 just to satisfy our local big tire 29” minimum height.

 

[Pro Stock John]

Larry is probably their biggest dealer, he knows the wheels well.

Heard back from Larry Hodge/Sanders. They told us exactly what we need to turn our 15x14 wheels into 15x12s. Just have to change the rear shells and we’re good to go 😎. We have the new 28x10.5 M/T L8 compound stiff sidewall tires coming this week- we’ll put those tires on those wheels and compare against the 28x10.5 D05 Hoosier (which is the best no prep tire we’ve tried so far).

Have a slightly larger camshaft on order with a wider LSA angle to put in it over this coming off season. Plan for this winter is much less than last year-

1) New cam/valve springs/retainers
2) Piston and rod upgrade
3) EFI for spark control
4) Possibly the Tin Soldiers unequal length 4 link brackets/axle side brackets
5) Possibly some fender exit headers- I like them under the car (sounds better IMO), but we plan on spraying 2X the nitrous next year and I’m not too into burning the paint/powder coat off the bottom of the car. The ease of spark plug access is really nice too.

Heading over there tonight to start doing the front coilover brackets. We decided to just bite the bullet and cut the spring pockets out and swipe the AFCO’s out of the front of my car. Gotta get them done before next weekend- have 14x175lbs and 14x150lbs front springs coming tomorrow. One more chance to go 5.99 next weekend before the season is over at the airport, we’ll see. The rain killed us this year, we lost 5 race days

Nice, Larry is straight forward and follows up.

I was asking about spring rates for front coil overs for Nova/Camaro and I was finding a lot of folks are running 350 lb springs. I asked in the FB Leaf Racer group.

We have 250s in it now, still a little stiff for our car. Thinking the 150s will be good on a 7” stroke shock for no prep 😎

 

[18degsbcregal]

Got the front end apart and all trimmed up, just have to test fit the long shocks and burn em in 😎. Gonna clearance everything so that the ball joints are what holds it up travel wise, and limit it to just before they bind up. Hopefully the bump steer is ok- we’ll see

 

[18degsbcregal]

Gettin there 😎

 

[BigLar368]

How long of a shock did the new towers allow you to run?

 

[18degsbcregal]

6” stroke would be ideal, those are the 7” stroke ones off of my 4th gen Camaro. They’ll work, but I need to space the tie bar off of the lower control arm a touch to avoid bottoming the shock out at full compression.

The lower ball joints in our TRZ arms are stopping us now from getting anymore travel. They’d need to be re-angled to get more.

Went today and ran the small tire shootout- lost 1st round by a nose against a big block nitrous foxbody. We got the lesser lane, went 6.38@114. Door to door all the way down, got nosed out in the last 15-20’. Tested for the rest of the day with the new shocks/springs. Went a new PB at the airport- 6.06@119. 10 degree launch ramp over .7s, 1 second nitrous ramp from 20-100% right after the launch ramp, leaving in 2nd. Wound up using the 14x175lb springs on the front- the 150s needed a crazy amount of preload to hold the car up. They put the adjuster collar inside the frame rail, definitely not convenient for on car adjustments. We’ll try and get some high travel ball joints on it soon, and tie the shock towers into the j bars coming through the firewall. Putting the nitrous timer in and losing the steering wheel button soon, I feel confident enough now that it’ll pretty much take the spray in the same place every time. Right around .8-.9s out in the right lane, 1.1s or so in the left.

My chassis guy did this and I thought it was a great idea. Thinking about it now it would have been a better idea to weld some tabs on the forward bars and run a much longer shock for more travel straight to the bars. Oh well....ya live and learn.

I'll say this, you have a hell of a lot of ambition to get them shock towers in, in a week.
