If I'm not mistaken, you have to run the stock serpentine pulley set up on the CS engine, which includes the alternator. I'll have to look at the rules.

If not, would the ECM etc be compatible with 16V power?

Think the rules require stock serpitine 6 rib setup for the water pump, which means ur still allowed an SFI balancer as long as its larger then 6.8" diameter.

Anyone ever see a Mac Bone Airconditioner??

8.1 BATTERY/CHARGING SYSTEM: Battery may be relocated. Charging systems must be functional unmodified and crank driven by the factory OEM 6 rib serpentine belt.

Guys as stated before I will continue to watch and see where this goes. I am not one to really go for folks telling what I can and cannot have on or in my car when I am spending my money. I have no problem spending the money needed to meet all safety requirements.

Since I do not work in the aftermarket automobile industry and only race for fun my outdated combo suits me fine and seems to be working as good as or better than most. I know a few of the other folks that have posted change car setups, engine combos and ECMs all the time. I guess when you look at it I am a perfect candidate for something like this since I have run my setup for longer than most folks.

Current 346 CI LS1 - 6 years never had valve covers off has run 10.47 at 3,350 lbs.
Original 91K 346 CI LS1 with LS1 intake - 5 years never had valve covers off and ran 11.94 at 3,650 lbs.

After reading what I just typed I must really be lazy or I spent the money the correct way the first time around. Heck it is time for a change you guys have talk me into it. As long as I can see what the sealed engine can do with a backup ECM when I am not racing the series! I may have just stepped into heads up racing!! I will be keeping the TH400 no TH350 for me.

Good find

Side question:

Will these crate engines still have warranty from GM or are we going to get the Abuse/Racing ban on them? If so, shouldn't the price come down!! Especially since we would not be getting the warranty and testing there products??

Not sure about that yet. I would hope we would get some type of warranty on them but i think since we will have the ability to over rev them, tune them and other things when not racing in the class, it would be hard for them to give us a warranty.

I don't think the price would come down for no warranty but i would hope that they can give us a good price on everything needed.

Great to hear man. I don't see why both the th400 and th350 would not be allowed. The first gears in the 4l60e and the 6l80/90e could be an advantage over the th400 and th350. Also the 6l80/90e having 4 non overdrive gears. This is definately somthing to think about for the rules as the electronic transmissions are alot more expensive to build up and have the potential for greater 60fts.

Also the th350 could have a fairly big advantage over the th400 by as much as a tenth. How much i don't really know. That is just something for those who would plan on running the th400 to think about. I want everybody to be able to be competitive on a level playing field and have fun. I am not sure how much it would cost to swap from a th350 or be able to have both.

This is a great insight into what it takes to prepare a Coyote class car.

http://www.powerblocktv.com/episodes...-powered-racer

They had 14 cars for their finals this year. With less than a second qualifying spread.

Nice to see the builds, I'm not sure how i am gonna hook up my dash guages and have the a/c work correctly. Gotta figure out which gears i want to use in trans and if i need to change rear gearing and switch to a 28. Won't really know on gearing until i run the car with the engine. Gonna be fun figuring this stuff out.

Our mph should be from 130 to 140. I am thinking a high of 138 mph.

If I looking at this correctly the engine is 525 HP at the flex plate correct? So my guess would be no more than 132 MPH with a car weighing 3,300 Lbs.

I want to say the engine will make more than 525 with headers but i am not sure if they dynoed it with headers or manifolds.

If you look at this link here you see basically what a ls3 with hot cam, headers, ls3 intake, and no accesories would make. Engine makes 523

http://www.gmhightechperformance.com...47643305952735

Coyote stock went as high as 130.76 at 3150. But i think that was in very close to ideal conditions. 138 is probably too high but i think it would be over 132.

This is what i would like to see allowed.... 10 bolt(maybe just the 8.5 lol), 12bolt, 9 inch, dana 60, irs 8.8(gto), corvette/5thgen/ctsv/gto irs, the irs dana 60 9inch and 12bolt setups and the solid rear swaps with those rears also.

I agree I am at no advantage with a MWC fab 9 inch, would have to get differnt axles. Little lighter ones would be better haha

I don't think there really needs to be many rules on rear axles. Any OEM or commercially available bolt-in replacement rear axle should cover that area. Any IRS equipped car can convert to an f-body style torque arm setup.

There are already NHRA accepted specs. for this for Stock Eliminator. The Corvettes and GTOs use a torque arm and the 2010+ Camaros use a four link.

Solid Axle conversions will just help eliminate breakage and down time. I back allowing them as long as they have a bolt in/c-clip eliminator axle. I think an 8.5 10 bolt could handle 550hp on a transbrake if the internals were right. The ring and pinion will be the weakpoint. I was doing 1.38-1.40 60ft times in my Caprice footbraking (but flashing at 6100RPM), and the 10 bolt held up fine. I had the same set of gears in my car for over 6 years, and they finally gave in this spring.

No way 140. at the start I think 120s will be good. Some new guys with stock style cars that just added the motor will be 115-118. That should still be alot of fun. If someone has the setup dialed and clicks off some 135 the 1st year your going to want to keep that to yourself.
I'd find out what the rev limiter is set at in the PCM, and gear off that. with a t56 I'm gona run 28's if the class lets it. thats what 90% of faster then 11sec Fbodies run. But I know the c5 and GTO guys can;t run 28s easy. You what to have it open rules to get cars in it. But I dont know if anynoe with the GTO is going to enter this. There was a GTO that raced a few times in mean street with a LS1, His user name was LSP?? I know some "factory-stock-street" NMRA class ran 26 max for years, but I dont this what would be wise here, the weights will be more. And the t56 is not as good for drag racing as race prep t5s all thouse guys run.
I'm betting the rev limiter will be 7K so 4.56 gear manual cars 132-134 is about all you can go. But somtimes you want to gear the car to 60 better, then perfect for the end of the track. The cars already traveling 125+ MPH at lets say 1300ft. so hitting the limiter a few times is not that bad for ET.

I dont care about the rear suspension and rear end brand. Do c5 and c6 need soild axle? I know friends getting 1.4s on stock IRS vetts with 16inch 26 et streets. TA setup is fine for any car, if they need it for a 10sec car?



I think I'm sure PSJ, Scoggin, and GM have talked about, they should have 1-2 different part numbers for the oil pan style motor. They have to come sealed, no way people are going to change there own oil pan or intake. lol thats not going to happen guys asking about that.

A 140mph pass with this motor all sealed and on spec fuel!!?! I highly doubt it...

I'm running 4.56s with a 275 Pro Radial and had to bump my Rev Limiter from 7200rpm up to 7450 to keep off of it before the traps... Car traps 125.50 with the 4.56s... That's with a 1.76/1:1 Glide Trans.

I'm willing to bet this class is 99% Fbodies.

I really think that the rules need to allow a 29"-30" max tire with NHRA style trimming allowed. I also think that the weight would be better if it were in the 3100-3200 range. The spec. fuel should be VP as it is available most places. I like C11.
