[1990jmcturbo]

my buddy (ctgreddy) is running the livernois dyno at back to the bricks this sat. in flint michigan. so im gonna get there early and try to get on the dyno before i have to leave to go to a wedding. try and guess what itll make?

2003 cobra factory longblock

CG fab single PTE 7675 billet wheel turbo
4r70w
built SRA w/ 3.73 gear
E85
23lbs of boost, 11.2 AFR, 15 degrees timing.

What fuel and is the converter gonna be locked?

 

[1990jmcturbo]

converter will not be locked. E85 fuel

 

[badcobra]

I'd guess 825-875. Not sure what kind of dyno.

 

[98cobra#1222]

Is 11.2 AFR what you would target if it were gas?? Stoich for e85 is like 9.8:1, or are you converting lambda values to a gas scale to get the 11.2:1 number. What does your fuel system consist of?

 

[1990jmcturbo]

yes its converted to get 11.2... fuel system is fore innovations setup twin 465's, -8 feed/ return, fore regulator/rails and 105lb bosch injectors.

 

[98cobra#1222]

Sweet setup, I would think you'll be around 790-825. Be interested to see what you put down as mine is a similar build only through a t56.

How do you like the 105's? I have a set in the garage waiting for a future build.

I'll say 800 just to keep the thread on track.

748 through the auto.

the 105s seem great. we didnt have any troubles tuning with them

 

[04cobra88]

Courious on why only 15 degrees of timing ? 827 is my guess lol

 

[1990jmcturbo]

i was just staying conservative. may bump it up too 17 degrees.

 

[badcobra]

Keep the timing LOW, max 17. No need to run more! Best of luck.

 

[Juiced46]

750/700

 

[jwcobra03]

743

 

[1990jmcturbo]

man mid 700s id be pretty dissapointed. we will see tho. my buddys 2.8 kenne bell made 760 on e85, 20-21lbs of boost factory longblock 95k miles. and obviously the blower takes power to make power. so my car on e85, turbo, 23lbs of boost. im hoping to just clear 800. we will see.

 

[Juiced46]

The big player in HP #s is the auto and the converter. My car on 18psi would make just about 600 but would go mid 9s@140+. You may make more then mid 700s but if it doesnt, dont get discouraged. The track is where it matters

 

[1990jmcturbo]

ben wakeling has a simular setup as mine, factory long block, same fuel system, same turbo hot side and same turbo. same trans. both solid axle setups and same size tire. he made 960 through the auto on 25lbs 17 degrees timing on e85. SO i figured 2lbs less and 2 degrees less i was hoping for 800. juiced 46 you are correct tho. my goal was to drive to the track a hour and go 9's then drive it a hour home and i did just that. but it would be cool to see a 800hp sheet. :rolling: ill keep everyone posted tomorrow morning

 

[Nightmare302]

I can make a dyno say you make over 1000rwhp. Dyno's are to tune cars and understand their powerband. They are tools and as such they don't all behave the same nor do all "shops" keep the settings the same. I've dynoed 100rwhp lower between 2 dynos. Don't get upset just because your cousins brothers sisters former roomate made 950 with a similar setup if you don't.

If it's a turbo/auto car, then it doesn't really matter what kind of mood the dyno is in, it will run hard.
