New Dyno Numbers!!!
I sent my motor to a dyno shop and they got back to me with the numbers today. 696hp/651tq on E85 and 575hp/536tq on 93OCT (at the crank).

Re: New Dyno Numbers!!!
The truth is that it is a going to be a daily driver. Thats why i had 2 pcms made (1 for E85 and 1 of 93OCT).

Re: New Dyno Numbers!!!
Excellent! I bet you're stoked to get that thing in and go!
So what c/r are you at now with the smaller chamber on the 243 heads? I don't think you'll have a problem with it, but you should have gone with '05+ LQ4 or LQ9 rods as they are beefed up... Also just curious, how have your IAT's been? I've heard quite a few people complain about insane IAT's with the maggie 112... I'm currently building up an LQ9, but really torn if I want to boost or not (wallet says no right now, haha!). I was leaning more towards a single front mount turbo... And looking at going with L92 heads.

Re: New Dyno Numbers!!!
The 243's offered more compresion and better flow with bigger valves than the 317's. To have the 317's cc'ed and all that good stuff was about $1000. I picked this brand new Patriot Stage 3 heads up for $800. So it kinda was a no brainer.

I'm a bit rusty on my memory right now, but I thought for sure the 317's had the same valve size and shape and flow #'s as the 243's and 799's??? Basically the same casting, just larger volume, and yeah, with the LQ4's pistons, lower c/r... I'm pretty sure that is the case, but either way, moot point here!

Re: New Dyno Numbers!!!
Did you get those figures mixed up? I would think that 93 oct would make alot more power than E85.

Re: New Dyno Numbers!!!
Probably not...the alcohol of the E-85 has a much higher octane rating, so it will stand a lot more timing and boost. It takes quite a bit more volume of fuel to make that kind of power though.

Re: New Dyno Numbers!!!
The numbers are right. Like "LONGHAIR" said E85 will take a lot more timing and boost. I went with E85 instead of race gas because in live in MN and we have a lot of E85 stations and its way cheaper than race gas.

Re: New Dyno Numbers!!!
Does anyone know what the actual octane rating of E85 is? We dont have a lot of E85 stations around here but about as many stations sell race gas and if we could substitute E85 for 110 race gas at about half the price that would be tempting. Probably have to build the carb for it though or get an alky carb

Re: New Dyno Numbers!!!
I think the OCT rating for E85 is 116. You can now buy E85 carbs from Summit or Jegs that are ready to bolt on. You also my need to put a bigger fuel pump in to keep up for the extra fuel that demand.

Re: New Dyno Numbers!!!
9 psi vs 12 psi is quite a difference. couldn't you just run a meth injection kit and stay with the 93oct, but still be able to run the smaller/higher boost pulley? And if so...wouldn't this combo likely make more power then the E85 at the same boost level?

Re: New Dyno Numbers!!!
Well after digging through some old Hot Rod magazines and reading an artical on a "750 HP BLOWN 6.0L" its time to send my motor to a new tunning shop!!! I got almost the same setup and Hot Rod got 683hp on 93. This may sound dumb but 575 ins't enough!!! I know it could do a lot better. 100hp difference!!! Well i already got way to much money into this motor mine as well spend a little more to get it to its full power level.

Re: New Dyno Numbers!!!
I didn't read the Hot Rod article, but were they going for extreme peak numbers?
Those 683hp on 93 might not be quite as usable on the road as your 575hp either, but I don't know what either power curves look like either... Might be something to think about. Whichever has the flatter curve could actually be funner, even if that means it has a lower peak... Also, were they using meth injection like 68GMCCustom was talking about above??

Re: New Dyno Numbers!!!
Its a good start.....
![]() ![]() I was making about 475rwhp (550 @ crank) on a stock LS1 in my 04 vette with the 112 maggie on 91 octane. Standard pulley with custom tune,intake and exhaust. At that amount of boost with heads and cam I would expect a little more.(not a whole lot if its a safe tune) Not sure iif you have done it yet but make sure you pin the crank. |
