I jsut personally think they will make 1100 to the asphalt, i seriously for them and Justin with all the work and effort and groundbreaking they are doing that they make more.

To achieve big numbers, you have to move a helluva lot of air.
I think our expectations were skewed by reports from Blakewilder before he vanished. My build was virtually identical to his, except for my intake. I don't see how we were misled by Paxton though. They couldn't have possibly foreseen just how voracious these engines would become, configured as they are. I'm pretty sure Paxton did not put their kit together with heavily built Viper engines in mind, so no bad on them.
Hell, even STS, with great success on every other vehicle they've built kits for, completely misread the Viper engine (even if it had been working properly from the onset). But hey, in all fairness, I wouldn't have the build I do without them. Well, them and several thousand dollars...
I talked to the folks at Paxton at great length, and they did know what my flow numbers and what the RPM range was, and they assured me that the Novi 2000 was up to the task.
They said that with pully changes (which I did) that I would have 9 pounds minimum, probably 10-11 pounds of boost.
We got 3.5 pounds of boost and made 650 RWHP. Joe Donovan said that he could do more tuning and get a few more HP out of it (25-50). But there was really no point as we were over 500 RWHP away from the target.

RamFromHell, FstJack, Scrambler1, What is your goal? 1100HP? or more?

I do hope you do, I think it will be a monster either way:rock:FSTJACK said:Thanks Tony, I hope we can make more but I have the back up plan installed..................
and yeah a little bit of backup

1300hp at the tires on just boost, C16 tune.
Damn!
The F2 is rated about 3-400CFM and 250hp or so higher than the 88mm turbo that was on Doms truck. It will depend on where Eric and Jack decide to stop in terms of boost basically, but the blower is good to 1600 crank HP (a Novi is rated to about 900 crank).

Boost is very important as it relates to volumetric efficiency as well as potential fuel density based on expansion. Even with the off the shelf Novi you could increase HP significantly if you designed an intake with mathmatically calculated reduction in volume to the point of injection.....Therefore creating potential boost. This in turn would result in some form of lag, and would still not give you potential/optimal hp.
I would guess top fuel dragster's do not use turbo's because its far easier to predict and tune a supercharged engine...In addition, are gaining the majority of their HP via fuel over boost design..Of course I am just taking a guess

you should do away with the s/c and go twin turbos make way more power
there is a tt viper running around dallas that makes 1700rwhp

I would love to see that dyno sheet. Question is, how often is he actually using all 1700HP. I bet he leaves it on the 700HP setting 90% of the time. At what point could you actually use all 1700HP? At some point it stops being a street car and is just a track/show queen. Not that I know where that point is either though.

At that kind of power level, I'd think it's more about bragging rights.

That is what I thought. Have you seen the dyno sheets on these builds?!?! Nothing below 3500rpm and then by 4000rpm you have over 1000ft/lbs of TQ. It seems that the more you want over 1000HP the wider the band of no power and the bigger the jump of power. How would any RWD street vehicle be able to plant all of that power? But I guess if all you have to do is show people a dyno sheet you are all set!:rock:
