Congrats. Very good numbers.
SWEET numbers, congratulations Eric. I can not even imagine how much fun your truck will be to drive!!
Thanks man! It's amazing how one of these trucks feel with a serious horsepower to weight ratio.
...as long as the three words are intake, air, and temperature, it's all good.
Nice numbers...congrats bro!!!!:rock: :rock: :rock:
Congrats on the results Eric, Ive been waiting a long time to see those. Any issues with the belt at all at high RPM's? Hows the streetability of the truck?
After I shimmed the bracket to square it up to the engine (some amount of adjustment will be needed on any installation, due to variances), the belt rides toward the engine side of the guide/tensioning pulley at idle. As the RPMs come up, the belt wanders a bit at first, then sits toward the radiator side of the pulley as it approaches red line. I'm quite confident that it will stay on, now that we've taken the engine faster than the "safe" tune will allow.
As far as street-ability is concerned, it's not much different than stock. You literally just use less gas pedal. Idle quality is near-stock, and the acceleration is absolutely linear. There isn't any lag or "power band". It's much more like you just have a lot more displacement, rather than a power adder.
hey rammy, jsut wait till you try to merge with traffic on the interstate
first time I did i allmost reended the car in front of me :burnout:
SWEET, can't wait to see the vid. Make some more vids of the truck driving around , that would be nice to see and hear.
Does it whine like the Roe, or whistle like the Paxton? I love the sound of a blower
Congrats on the numbers. You must be a kid in the candy store holding all the candy. Maybe both you and Dom can come down to Famosa and run this March:dontknow: That would be a site to see. :burnout: :burnout: :burnout: :rock:
Funny you'd say that. As soon as we left the shop to cruise to the burger joint, I go through a couple of gears and realize I got where I was going a heckuva lot sooner than I was used to! Had to down shift and put her a little sideways to reign in my speed! Getting on the interstate was no prob. I was getting used to the power by then. I'm discovering that I can haze the tires at just about any speed.
Seems like all of the centrifugals whistle, and this one's no exception. It's definitely a deeper-pitched whistle than my Paxton.
I think we need some vids
Just a sick truck!:rock: I take it that 921 was rear wheel power?
This kind of a day for me seems so far away.:argh:
But seein this truck that I know took Eric a long time to build come out so
Yep. Better than 1050 at the crank, figuring on average auto trans drivetrain loss.
I noticed that with my Procharger there was a certain RPM that "whined" considerably louder than everywhere else. Remember it being around 65mph cruising. Not that I spent much time there, I was either faster (interstate) or slower (in town traffic). How do you like that chichichi sound when you close the throttle coasting down from around 100-120 (or readline)?
Haven't found a particular RPM where the whine is especially loud, but I've only driven it for an hour or so.
The race bypass noise you're talking about is certainly noticeable. Matter of fact, if I'm correct, it really shouldn't "chichichi". It should just "cshhhh". That rhythmic sound I believe is compressor surge. I'm considering sending my charge pipe back to Justin to have another bypass valve added for more efficient discharge of the excess pressure. The F2 just moves so damned much air!
