Not bad at all, I love the white Z28 Vert. Look like mine almost just with less miles (damn the long trips to school).

 

in mustang land thats enough mph for 12.60-12.80s.

 

How? That's getting into cam range numbers. His numbers are quite good for what he has.

Not quite unfortunately. Probably not even 2-3 RWHP out of leaning it out more.

Great numbers!

 

Nice no.s bro! Seriously for a 95 LT1 with 73k original miles NOW its time from some head porting and a nice cam to put those 1.6RR to work

 

Thanks for the input all.
I dont plan on porting the heads and installing a cam until I need a reason to have to tear the engine down. It is has reached my expectations already at this point and I am verry happy with the way it runs.

So if the opti goes or somthing starts leaking bad then I plan on at least going LE2 port job and LE1 cam. I dont want to rev the engine to 6.5K (LE2 cam) because I prefer to have engine longevity and still decent gas mileage.

The car currently launches pretty good on these street tires, the big thing hurting 1/4 mile times will be my weight since I have the heavy vert and some hi-fi in the trunk. I might be able to throw some drag slicks on and sneak a few runs past the 10-bolt rearend.

If I can hit some mid 13's on street tires and some low 13's on drag slicks I will be very pleased. The current goal was to be able to evenly compete with a stock LS1 and maybe wack a few in the process. It appears that this has been accomplished.

Plus needless to say if this engine did get heads and cam it would be a beast.

 

excellent numbers! I would like to get my car to 300 rwhp also..

 

The Superflow dyno can be operated in a couple of different modes, if I recall the info from an article in Hot Rod magazine about 1.5 years ago. One of the modes is basically a Dynojet inertia emulation, and produces similar results. It can also run in Eddy-current mode, similar to a Mustang. You need to ask the dyno shop what program they used.

"STP" is standard conditions (29.92"Hg, 59degF, 0% RH), which produce a shade more HP than "SAE" conditions (29.235"Hg, 77degF, 0% RH). Not unusual to see.

I would have expected a bit more gain in leaning out from 11.8:1, but I'm not going to argue with the programmer.... he knows what he put into the program and why he did it.

 

Wouldn't the 4.10's account for a little hp loss as well? It thought that higher gear ratios cause your hp to drop slightly on a dyno.

 

I would tend to think that a 1/1 ratio would be more efficient than a 4/1 ratio.

Based on that logic a 3.42 would have less loss than 4.10.
I think I will differ here.

 

You can search for a lot of information regarding the various testing standards
such as SAE, STD, and STP. The closest simple comparison I have come up
with is that SAE numbers are about 4% lower that STD/STP numbers. STD and
STP are the same correction factor.

My first pre baby cam dyno runs were done on a Superflo dyno with STD correction
and I was at 310 rwhp (297.6 SAE). Just reduce your numbers by 4% for SAE.

 

Nice numbers.

 

Very Nice #'s Smooth curve as well.. If your happy that's all that count's..

 

Awesome numbers for a bolt on car, looks like you leaned out a hair in the upper rpms.

 

I must be confused about what is rich and what is lean.
I though as the A/F number dropped the car was running more rich.

Someone please explain this to me.

 

It leaned out when he got out the gas.. otherwise he's running lil fat.not that bad .
