Competition Fletcher runs a 10.11 ET

[Stefan Kondolay]

Maddog I heard your truck runs 7sec according to the president of the DHRA is this true? :-laf I heard this from a member of the NHRA racing community, I told him not a chance was I wrong?

NOW, that's fast but, w/ a million HP, it's expected :-laf

 

[Piers]

WOW, was that slam from a 16 sec twin turbo'd Duramax

 

[COMP461]

Fletch that run look a little rich , with the care package coming your way from NITROUS EXPRESS you will be the first in the 9’s with a street truck, then you’ll have to get a NHRA license and a chassis tag . Not many 9 second street trucks . you know that the magazines will subtract a second or more, heck in some cases you can get credit for a 6 second truck and never have to run down the track with a successful pass.

 

[Stefan Kondolay]

Piers, I know that your not that familiar with drag racing, but let me give you some information about the reason I CHOOSE to run my truck at the E. T's I do.



First off bracket racing requires being consistent.

Secondly my edge box wasn't working right. (not to worry they are fixing that)

Third reason, my LLY's torque management systems kicks in I engage 4wd so my 60 foots are 2. 50's.



If you look at one of my time slips I ran 16. 01 at 60. 77mph on the brakes with the predator on 65hp setting with a truck that weighed in at 7895lbs.



It was kind of funny though out of all the trucks that attended it was the only one that got a standing ovation from the fans when I took out the two time bracket racer of the year in the second round of the gamblers race. On this run I went . 007 on the tree and he went . 036. I ran a 16. 18 @ 67mph on a 16. 15 and he dialed 9. 80 and ran a 9. 79 @ 133mph.



By looking at my average mph do you think I might have been sandbagging a little. Heck even ask Pat my mph when I red lit against him, I even got on the brakes that run so that people couldn't tell how much I was holding.

 

[Stefan Kondolay]

Oh and Pat thanks for not rubbing it in my face for losing to a BD truck. I :{ all the way home.

 

[Pat@BD]

Dont you guys be draggin me into this

 

[Pat@BD]

Oh and Pat thanks for not rubbing it in my face for losing to a BD truck. I :{ all the way home.

Hey no problem, besides technically I didnt beat you, you beat yourself. But I did the same thing the next time. That damn Red light.

 

[TurboTweaker]

Never did like sandbaggers, especially the ones who come sliding through the trap with no brake lites... ... hmmm wounder why. i'd rather take my lil truck and run it hard and as fast as my 6 little cylinders will take her. i didn't know a 390hp truck with a 5spd would got 15. 00 hmmmm i got alot of work to do then. i had 375 and ran 15. 460. back to the drawing board huh Fletch and Comp. Well Great job Fletcher, 9's... . heck the 8's are doable on the bottle.

[Stefan Kondolay]

I love sand bagging and wouldn't race any other way. No brake lights that's a good idea. Going to the truck with wire cutters. Oo.

 

[TurboTweaker]

Or just un plug them! but what do i know i'm just The Fat Kid. but if you like wireing go right ahead.

Yep Stefan the old DTT reactor sfi flexplate could not hold the power of a 7sec blast. :-laf

Hey Maddog,



This is not a joke, we take this kind of thing very seriously and so does Reactor, we were contacted by them today requesting our opinion on what happened to this plate. They were sent pictures but did not see the plate. At their request today it came in and Bill sent him his findings, he concurred but wanted us to overnight the flexlate to the SFI guys for analysis. They will independently have it analyzed . Bill went one step further and sent another plate we had in the shop to an independent testing facility to see if they could simulate the breakage they saw in the plate you sent me. You guys look at the plate above, it very clearly illustrates there was no rotational damage to the flexplate. In other words the engine was not turning when this flexplate broke. Bill wanted to be 100 % sure before he commented what he suspected happened occured. Since he is not a mechanical engineer or a metal specialist he refered it to the experts that did not care what Reactor or SFI had to say , they would give their analysis based on the damaged flexplate. We run this exact same flexplate by the same manufacturer as do a lot of other racers. This flexplate is turning at 7800 rpms in our car within 3 inches of our leg. When I tell you this is not a joke , you better believe we mean it. It will all be handled by professionals from here on, Reactor is a very very serious company and this is what they do, they are awaiting the SFI analysis, this is very serious and all involved with be dealt with accordingly.

You are right Stefan it is serious, but be careful when you make comments about the damage happening while the engine was not turning.

Darned Cummins Engines. Must be a engine problem.



The fracture probably started from the high frequency generated vibration caused from the harmonic resonance of the first turbo, matching the compressor frequency of the turbine drive pressure pulse, making the drive flex plate go into a sympathetic pulsating wave frequency in a forward and rearward motion, eventually causing it to fail. While not turning.



Or maybe the engine just makes too much power!



The parts that break behind a diesel are different than the ones that break behind a gas engine. Trial and error will lead to parts that will hold up. Theory has to be tested before finding out if it works.

 

[sbentz]

To clarify: We ran a Reactor behind a small block injected alcohol small block for hundred of runs. Never an issue. Great product. But - torque breaks even the best parts.



We are having fleets breaking input shafts in semi-trucks that never did before. Why? Who knows. They last behind a 600 HP 2050 TQ engine, but fail behind a 475 HP 1650 TQ engine. Torsional vibration is the hardest thing to understand. We have engines snap the nose off of a camshaft, and find that the viscous crankshaft vibration damper has locked up, and no longer absorbs vibration. Twists a 2" diameter can nose right in two. You could not duplicate the failure with 4000 Lb Ft of torque.

 

[JoshPeters]

Sleddy, it could be the massive compression of the Mighty Cummins, that when it stopped so suddenly... . it broke!



Kind of like needing that extra clutch in the OD section when there is a one way sprag clutch that holds as well. The only thing that clutch "has" to be there is for reverse. (Yes of course it HELPS hold the sector from turning, but I have been there done that, fried that clutch pulling someone out of a swamp, trans worked fine, no reverse)

I have run REACTOR flywheels for years , and turned then 10,000+ , and still run one on my diesel , when Maddog told me about this I looked at mine , I am not an expert , but it seems that the recess for the crank should have a rolled fillet instead of a sharp turn , but that’s not where his broke , . I never liked the concave flywheel, that is why I run a flat one , What ever the problem , I’m sure that reactor will fix the problem , an reengineer the product to stand up. I also have seen that same type of flywheel on Outlaw Pro Mods , which make as much torque as we do, and they work fine. The problem is in harmonics , if I was guessing . This company is making an effort to make good products and there is a learning curve.

Thats 389 hp not 390 . uncorrected the weekend befor!!

My driving skill have been honed to the finest with the 5sp. There are a few tricks pm me and I will share. And that was with a 2. 132 60 foot time. And at 7000lb. Now if I could get a 1. 80 60 foot time and a light under . 400 life would be gooder!!



Take it easy Andy
