Seen the video, isn't good quality an all you can see is smoke. Being there in person was way crazier, especially when your sitting at the 1/8th. Go Pro footage would be the sh** to watch!

i knew it was only a matter of time till one of those A.R.D. hack jobs went into the wall glad the owner was ok but the guy from h-town camaros is a dumb *** me and rooster tried to warn these guys about A.R.D. and we got our posts deleted and banned from their web site so technically its partially his fault because he did everything in has power to cover up all the evidence we provided to them showing A.R.D. was a POS shop so no one would get screwed, well i guess it only took someone loosing their ******* car before the tards over on h town camaros will listen. WELL ARE YOU LISTENING NOW? A.R.D. SUCKS and always has.

They're more interested in protecting a buddy-buddy sponsor than protecting their members. Cash is king

That engine was toast well before the 1/8th mile mark. Glad it didn't take out the Lightning and ruin two nice vehicles. Boosting engines with glass pistons is a risky proposition regardless of how well it's tuned. Getting greedy with boost & tune just makes the kabooms come earlier.

That's what I hear as well. He didn't want any of the VTech the other night back from the track when I was in the civic.

600-650rwhp is not really getting greedy with the LS3. I think ECS has 75 out there now over 700rwhp, and only 2 have popped. Their cars see a lot of track duty and some are full Mile run cars.

Through an automatic? With stock internals (no cam, no spring upgrades, no ported heads, nothing done)

ECS typically uses centrifugal blowers, which only make higher boost at high rpm. The Whipple pushing 600+ rwhp on a 100% stock L99 engine / auto trans = KABOOM waiting to happen. Keep in mind these blowers make full boost at 2K rpm. Different stress loading than a centrifugal blower creates. If you ran a 600 rwhp centri blower against a 600 rwhp roots/screw/tvs car, the centri gets walked.

Not really. The centri guy downshifts from a roll and launches at a higher rpm. From there he stays in the curve where he has that peak power. The trap speed on 600rwhp whipple car is going to be pretty close to the centri car. It is still mostly a driver's race.

It is still in the tune. You make a good point, but it is a reason to be very conservative on timing down low on those whipple cars.

Joe, if both setups have identical peak hp numbers, the PD blowers will typically have a broader powerband. For example, when I shift my Z06 at 7K rpm (619 rwhp) it is still making 600 rwhp at 6K rpm. The HP curve is flat all the way across my racing rpm band. On my Viper, the centri climbs a good 30-40 rwhp from start to finish in the racing powerband. Centri hp curves model more like an NA curve on the HP.

Also, you guys are comparing ECS Corvettes at nearly 800-900 lbs weight difference vs a 5th gen. That extra vehicle weight also puts more strain on an engine.

Just a FYI Chris posted pics of his car at ard and the front cover was off in one pic and in another there is a valve spring tool on one of the springs............................


Looks like a cam swap to me.


And your statement on the postive displacement blowers .vs centri's is just RETARDED. CENTRI's for the win!

Nine Ball

iTrader: (38)

Retarded? All else equal, equal cars, you are saying a 600 rwhp centri beats a 600 rwhp PD blower setup from a roll?

Please explain. Your logic defies physics. We aren't talking all-out max builds here, it was a statement comparing equal HP setups. Of course the centri dominates all-out racecar builds, except when the turbo(s) arrive.

- First: Very glad the driver is OK! Think that is the main purpose of this thread. Not to bash LMP or other.....

- I've seen Underground cars crash, and I'm know even LS1-Tech Sponsors have shop/customer cars crash at tracks/blown motors/ext.....Did not see anyone bashing UG, or other before after those accidents. Unfortunately A.R.D. looks to be LS1-Tech's *** rag. I remember not too long ago it was Hennessey.

- It has nothing to do with the track. LMP has been building a solid rep for track prep and hooking. Many longtime drag racers that have had the same cars at other tracks, and have had new personal record times at LMP. 9 times out of 10 it's the drivers fault. Still take that on a case by case basis. I've snapped 3 shafts the last 3 times I've been to LMP. Between driver error and the track dead hooking snap-ola. It's not the tracks fault. It's mine.

- If you were not there, you don't have **** to say.

- Very happy the driver walked away, and wish him all the best on getting this worked out. Please keep us posted on his status. Best wishes on a speedy recovery.

- Stay on topic!

- That is all.

You are just making too many assumptions for this bench race. Belt slip? Restrictor plates? Odd timing curves/tune? Gearing? Blower efficiency? Those are all factors.

It just doesn't play out the way you are saying.

I guess that bump at half track that I usually hit is just in my head and not really there.

ysb02

In theory your idea may work out but a PD blower ripping through the gears is bound to get heatsoak and lose power. I think where the centris really accel is the ability to easily inject meth and have a much better capacity to cool the compressed air. You may need a 650rwhp dyno PD to equal a 600rwhp in real world conditions. That PD may be only making 600rwhp in a roll race.

Think the track hooks fine, there weren't a lot of traction issues Saturday night except for the nitro bike and the street class cars. And that old mustang which was a suspension issue on the car. The bump iS there, I'll look at some
Of my videos and I know in person you can see a car go over the bump might have video proof though for those who are saying the track is perfect.

I couldnt figure out how to link it and it show up in the post directly but heres a good link to PD vs Cent between my buddys 2 cars. C6 made 760rwhp & GT500 809rwhp.Both 6spd both from a roll just for the debate http://youtu.be/qhvjTvUnzp8

winters97gt

That has zero relevance to the argument right now. You're comparing two different cars with different gearing, weight, etc.
