Yes i will be at irwindale speedway next Thursday night. I ran a pre-mod pre tune run there it was 8.8 at 79mph 60' 2.07 (8th mile track) i will post the new runs next week

Crazy good #'s!

[SRG963]

Very Nice Numbers!

[Eric_GT]

I think that is the highest i have ever heard?
Being a novice at this, how can one car produce 20-30 more hp than another with the same set up?????

[r33pwrd]

50 more HP than me with the same mods (I have Vararam vs your rotofab)

['02 ws6]

No two dynos read the same Eric, so there are always variances, but a strong number is a strong number. The best comparison is done with track times, so don't sweat another car reading 20+hp higher than you on a different dyno.

Yeah, I gained 30 whp from the tune according to the numbers.
However, the thing drives like it gained twice that! lol

An eighth mile conversion chart shows a quarter mile at 13.3. That seems to be on par with other cars with your mods, but definately has room for improvement in the 60's. But damn do the dyno #'s blow others away. Do you know the DA you ran at?

Haddad's dyno doesn't use the wheels and tires of the car, or so I've read. His has some type of adapter that bolts on to the axle flange.

Wow -- a 5 mph improvement in trap speed vs. pre tune. Very impressive! The car is making good power, just need to work on getting it to hook.

I wondered why their numbers are always really high.

I saw one of those on a show before, kind of strange looking.
