Where did he say 1300rwhp??? He said 1300fwhp and 900rwhp through his auto. It's Yates, not Yeats, and you know the guy?? lol

That viper has a auto now, its best time with the 6 speed was a 8.75

Bryan, here is his original post again.

I'd like to hear more about how Dean is able to make 900rwhp thrua C6 on pump gas. Is it a 351W? What compression?

Exactly, me too!

8.3:1 PSJ...check the thread you quoted! Did you and Bryan attend the same reading classes? lol

Never said I knew Yates, I said I new the guy at the machine shop that does all of their heads. Smart ***

I guess I really should start wearing my glasses!!!! I thought that wierd.

8.3:1, 900rwhp thru a C6, that's pretty sharp. I'd like to hear how that setup gets by on strictly 93 pump gas.

im gonna go look through my mustang mags and see if i can find the article on this thing. i heard its in either MM&FF or 5.0 mag

With that compression pump gas is no problem, and by looking at your sig, you could do it to, the key is watching your timing.


You have all the tools, there is no reason you could not go try it.

There is no reason you should try it either, though.

I dont think I can get below 9.5:1 with my setup. If you have any suggestions other than going back to a 350, let me know.

Bryan, want my reaction to your comment? It's an interesting comment.

I've been accused of being a dynomaniac, and it's actually probably true (much to my chagrin).

Now, there are a lot of things that I do not do to try get the best dyno number. I dyno through an unlocked turbo 400 transmission. I dyno on 28x10.5 slicks. I dyno through a five year old Moser 9". I typically dyno with a 4000+ stall converter. I don't have a lightweight driveshaft. If I wanted to hit 900rwhp, I would have to do the following, in my mind, to get there. Let's keep in mind that I am not saying I will do this and I am not going to address peaky vs. flat power curves either:

900rwhp combo on pump gas
6.0 block, +.030 over bore
8.25:1 compression
A1 head studs
AFR 225 heads
88mm mid frame turbo
4" downpipe
2800 stall converter
T400
26" tires for the dyno
A2W intercooler, a big 'un

I think most superchargers eat up too much HP to play the dyno game, so I would jump ship and go turbo. YSi Mustangs with C4 trans hit 780-825rwhp all the time, and the best #'s I have ever heard of for a stick YSi car is 890rwhp. But I would not even try to race a stick car with 900rwhp personally.

In the end I think your combo is problematic because of:
a) hp loss to turn the blower
b) belt slippage issues due to stepup of the blower
c) a2a frontmount limitations
d) limits of stock pcm

I think 900rwhp will be tricky for you on pump gas, and I think that 1100rwhp on pump gas is impossible. If you had a 540ci big block with a 88 millimeter turbo I bet you could make that power but that's not your combo.

900rwhp with an a2a fmic might be doable, but we can't deny that a2w with ice will run cooler.

turbosaleen

no meth

just air to air intercooler 80 mm turbo on a custom kit with full exhaust to the rear of the car 4 inch and a 363 cube 302 based motor 4.125 bore dart blockwith a 3.45 stroke runing cnc ported tfs highport heads wic probly are comparable to a radicaly ported ls1head

340 cfm intake 250 cfm exhaust.

liek i said 8.3-1 compresion air to air intercooler custom ground 689 lift cam for the turbo..
c-6 with a lose converter wich kills the rwhp number my car would eaisly break 1200 if it still had a standard in it.

the viper you speak of i realy would LOVE to race cause i have a nitrous kit spraying a 75 shot wich gives me aprox 90 at the rw due to the intercooling effect the numbers i posted before 8.91 was pure turbo no spray

im sure the car has a 8.60 or 8.50 in it on the bottle as it made 989 rwhp with the spray and that much a dif is easily worth 3-4 tenths.

anywaycomparing my car to the viper is aples to oranges as he has a almsot 600 cubic inch engine with twin turbos not a 362 cube small block with a single
giveme a 550 plus cube engine and ill run 7s on pump gas

yes that was me at the PGD

John,
I believe that is the most you have ever said to me

Here are some afterthoughts:
I never said it would be easy.

At the request of nitrorocket, I contacted some other Piston manufacturers, and Weisco has said they can make me a 8.5:1 piston for my setup, that can handle 30psi safely . Odd that JE could not. I do not believe that 30PSI is required to hit 900RWHP or 1000RWHP, 1100...well only time will tell.

Remember, I said before the gasket gaveway, I had hit 811, and 767 at 5200.
The exhaust is open all the way to the exit. I have not seen any belt slipage either via, the belt or the dyno graph.

PCM and Fuel:
The PCM has been reloaded with the HPTuners 2 Bar setup. I still consider this stock, because it is using all of the stock tables exect for the VE. If you are not considereing this stock anymore, I will except that. When most people say nonstock PCM I am thinking of FAST, Big Stuff, Etc....The only reason that I wont use any of those is that they cannot pass inspection because no ODBII, or they dont have drivers for the gauges. Being that no one has ever made 1100RWHP with a stock PCM I think it is a little premature to say "it cant do it", Everyone said that it would not do 800RWHP, hmmmmmmm. Remembering that the limitation was the VE table and now HP Tuners has fixed that limitation. The Stock GM PCM is the fastest PCM in the automotive world and is more than capable of handling at least 1000RWHP. Only time will tell if it will do 1100RWHP.

Also with the 71# injectors running 80% Duty Cycle, I can make the system see 10:1, which means it is below that. AKA plenty of fuel. There is more than enough fuel there for 1000RWHP. Just not sure about 1100. I am running either -10 or -8 from the tank all the way to the rail. So there is plenty of fuel there.

The AFR heads are not enough. They would be too limited for this application, hence the need for the new castings that I told you about which will outflow the AFR's and the ALL Pros. The LS6 heads dont have a thick enough deck to support the blown application, as the AFR's and the new castings have.

The AFR 240CC that they are working on may be enough, but again I am using the new castings I told you about.
There is a car on the procharger website that is making 1100RWHP on pump gas, it is carb'd. A fuel injected car is more efficient. So I am going to have to say it is very possible.

Cooling:
I very well may need a bigger FMIC. And I may need some sort of additive like Alky, or meth, but I will not even think about it until I hit 1000RWHP.

Dont limit yourself...Anything is possible with enough time and money.
