Yeah, she make 29 lbs at 3,000 rpm. Guessing 2,200 hp. I'm running 21 degrees of timing and pulling all 21 degrees back out to leave the line at TDC. I can't blow off pressure maybe try a air throttle control next

I have a hard time believing that thing makes that kind of power and boost with ZERO degrees of timing. You sure you retard box is working? We have guys who run screw blown cars in Drag Radial with no throttle enhancer and have no issues making them leave

I agree, that why we are thinking it's a tire issue. I was pulling 15-18 degrees last year (running 25 degrees then). Here is the last pass, data logger shows timing coming out, verifies with timing light afterwards.

Love this thread! The pictures and the comments have been awesome!
I have to say that that graph looks as if you are running the high hurdles! Wow!
I race with a guy in Top Dragster that runs a single 4bbl. on a 5" BS Chevy and runs 6.50's at 2-3,000 ft. corrected. We find out all the time that sometimes less is more. I know that most Brad and the like combinations tune with timing. I would take some blower out of this thing and creep up on it. It is WAY too violent at the current setting and I would hate to see you or anyone get hurt. I agree with Monte, just not as angrily, that no amount of suspension tuning will make this thing go down the track at its current power setting.

I'll try the tires and shocks this week, a Monte say they are doing it with screw blowers, I'll bring a spare pulley just in case

If I am seeing that graph right, when it stands the shaft speed graph straight up, it appears to be at 5800rpm. Where are you trying to leave with this thing?

Now while your tires may be bad, that tire will hold crazy power. I just watched Jamie Hancock go several .990 sixty foots on them over the weekend and run in the 3.80s

That is interesting, I didn't even look at that this pass. This was pass 3 where they all did the same thing. I tried to step it up and set the rev limiter at either 4,200 or maybe 4,500. Look like it didn't hold. The other 2 passes were set at 3,000. It also looks like the timing wasn't all the way out before drive shaft started moving. I'll look at when the transbreak was released and check the other 2 passes today

You are right, I set the two step and figured it had to be working. Brian Robbins had been helping and reading all the data and haven't been a concern of mine before. He wasn't there. Damn thing was launching at 6K all three passes. I feel like such a rock. I have to spend some time and figure out how to work that thing

Don't take this the wrong way, but it is obvious you are VERY new to this and need a lot of help. My advice is either put slicks on the car until you get somewhat of a handle on something, or get some help. Many more attempts like that video and the motor is going to be hurt.

Radials and big power take several things to be successful. Good track, which Milan RARELY is. Very well set up car and someone involved who really knows something about racing on radials. Not sure any of those are present here

Someone above said I posted something "angrily". Don't even know what that means, it's text and as such there is no implied emotion. It's just to the point with no sugar coat. That's the way I like to hear it myself, so that's the way I put it out. That said, myself or anyone else on here could say "try this, try that" but frankly it wouldn't matter. The amount of experience on the board with radials and big power is small. The amount with radials, big power and a blower is likely ZERO. So you need to find or hire some help to get you sorted out

Thank you Monte, yes very new to racing. I can almost count my passes on a drag strip with my fingers. I had a blown Hemi street car and it fit the rules pretty well and bored to death of driving it down the street. I'm sure trying to launch on leaf springs probably only makes it worse.
Many of the local drag radial guys have taken me under their wing and have tried to help. They really are a great group of guys but between the leafs and the blower it is quite different from every thing else.
Brian was helping a ton on tuning but he is no longer driving the Skinny Kid car and isn't around now. I have a blown alcohol 10.5 guy coming to help for the last race to make sure I don't melt anything.
Slicks could be an option, people put a lot power to radials.....slicks are still that much better? (remember newbie)
When I built the car the class called for stock style suspension, that has changed. Maybe 4 link it now? More conventional turbos? Just work this combo for a while with slicks? I guess I could turn the blower down some for now might be a good start

Nothing wrong with leafs, they work fine when setup right. The problem is the tire. Drag Radials are great, WHEN the track is prepped for them, especially on big power. Guys go fast on radials when the track is flypaper sticky, the rest of the time is a smoke show. This past weekend at Radial Fest, with a track prepped especially for radials, they didn't even bother to attempt to run in the heat of the day when track temps were high. So to directly answer the question, YES, at your power level slicks are MUCH better on a marginal surface. Which Milan nearly always is at best.

One pass we attempted during the day, we had enough in the car to MAYBE go about a 1.25 sixty foot and it was instant tire smoke. As soon as shade got on the track and temps went down, we were right back to 1.05, 1.06 etc in sixty feet. And nothing about it is easy. You need a VERY good handle on car setup and power management

Blower, turbo, nitrous........doesn't matter. Big power with any of them is hard to manage on radials

Didn't mean to offend anyone with the "angrily" comment. I put the icon on there trying to have some fun. This is a great read and a very cool car. I hope you can take some power out of it and make it go down the track without lifting.

Well I tighten the front shocks, swapped the rear shocks. 315 pros, Fixed the two step. Got a 3 hour class last night on how to work and read the Racepac. Assembled 3 drag radial guys, 1 blown 10.5 guy and one Blown Pro Mod guy to help. Looking forward to seeing what can happen Oct 7th at Milan. Fingers crossed

All the best to you. It is an animal of a car I love it, keep it in the middle !!!

Thanks! I'll post the results

3 passes yesterday at Milan. New tires, wheels and shocks an fixing the 2 step helped a ton. 60 foot time 1.22, 1.17, 1.16 dead hooked each time, no adjustments, I sure it can take more. power falling off at 330, we are getting closer
here are two runs

Awesome! 1.16 sounds great! No need to pedal the throttle?

Timing is pretty much out for the first second, power coming in until 3 seconds, its working. I peddled the first run, It's been a year since it launched it freaked me out a little

The 1.16 video looked like it went up on the wheelie bars nice and easy. I think maybe shifting instead of lifting. Good job! The launch looked great, just need to be able to stay in it!

Jut cause I'm still thrilled its starting to work
