Most if not all of the FAST "doorslamers" have moved away from roots blowers and even nitrous to some degree. They choose centrifugal blowers or turbo(s), leaning more towards turbos it seems. True, they didn't pick a fair comparo for the rootsblower. I think it made 8psi, where turbo and centrifugal were at 9.5.
There's nothing wrong with centrifugal blowers and I always anxiously await updates of your blower set-up, but I just want to point out that the centrifugal made the most PEAK power. Specifically, it made the most power from 5700 to the 6000 rpm redline (and granted, was still climbing). However, the turbo made the most power from 2500 - 5700 rpm. Plus, from about 3000 - 5000 rpm, the turbo made quite a bit more power than both the centrifugal and the roots blowers.
Hot Rod article The real mistake in that article was that they "left off" the turbo intercooler to "make it fair". In other words, the complete turbo/intercooler package would have made more power than either of the blowers. I've just let my Hot Rod subscription lapse. I'm tired of that and other rags being written by a bunch of idiots with all kinds of excuses about why the dyno was too expensive or the torque converter stalled too high or whatever. I guess I'm getting too old, but I miss the "Old Days" when the magazines were worth keeping for reference. I think that Hot Rod is about to repeat their "van phase" next anyway and I don't need to see that. I will miss Marlan though...
Re: Hot Rod article Yes, the Turbo would have made more power with a intercooler. For that matter, so would the Centrifical Charger (alot more). Would the turbo had made more... probably. Don't get me wrong, I love turbos. The only down fall about them to me, is all the excessive under hood heat, ducting, and haveing to run a oil line to the turbo. Anyway you look at it, boost is just plain cool no matter what's making it. :beer
Don't forget COST!!ou: Roots-style will always be eye-candy.. Turbos are probably the best boost.. Centrifugals are cheap, easy, and making HUGE STRIDES towards BEATING turbos!! But Rich, your still right!! any boost is :bglasses: with me!:TU: :TU:

Yeah, I can't wait to see what people will be able to do with the new blocks and some forced induction, I think 1500 horsepower+ should be possible with some massive twin turbos and intercooling, at least I would hope so! I am currently in Japan (military serving overseas) and I desperately miss my BBB Sport Wagon and American muscle....but these frickin Nissan Skyline GTR's over here are ridiculous, the done up ones are usually at or above the 1000 hp mark. I got a video off the net of one doing a dyno run at ~1000 hp...it's INSANE when the boost comes on cause when he starts up and runs up to 4th gear, it sounds like he's getting on it....then it holds at like 4000 rpm or so and THEN the dude opens it up, HOLY crap that's a lot of boost. Love that sound though. The best part is two guys(idiots) sitting on the rear of the car while it's doing this to keep traction, I don't think you could pay me to do that, but I guess ricers will be ricers! Well point I'm getting to is, if they can get 1000 hp out of a ~2.6 liter inline 6 cylinder, and Buick v-6's can get even more than that....I'm anxious to see what a mega blown/built 455 would do! The scary part about these Skylines is that they're stinkin everywhere in at least mild tune (400+hp), and there's no telling just how fast it's gonna be. Hopefully I'll be able to run with them soon, I'm putting an SR20DET (2L DOHC Turbo) into my 1500 lb Datsun, they run 205 hp stock. Enough ricer talk....I miss my Wagon. It was on the verge of 13's when I left it in my parent's care in June. Can't wait to throw a posi and Almn. Stg 1 heads on when I return! -Andy Yokota Air Base, Japan Keepin Americans safe in Asia 1969 Buick Sport Wagon 455 ----> trac limited 14.14@99.9 mph 1972 Datsun 1200 1.5L -----> trac limited 16.1@85 mph, does 15's now (ooooh look out! heheheh)
Although I've been working on lowering my CP, I'll still be stuck with 5 to 8 psi......... with this motor anyway. Even at that, it's pushing the stock rods pretty good.
I hear ya Rich.. You planning on some TA Sportsman rods and new pistons anytime soon? Are you just trying to get the car up and running at Vegas, or are you gunna keep it together for awhile?
Well.... I really don't want to invest anymore into this motor than I alreay have . I'm hoping that this will last until I can get a new block to start building (slowly). I suppose I could have invested another 7 hundred plus some $ for balancing the asymbly again as well as having the new rods pressed on (ok say 900.00 with it all said and done)....... but my wife is already not too happy about the 900.00 bucks for machine work, rings, cam, lifters, and bearnings.... that I spent last week Anyway, I think not pushing anymore than 8psi as well as setting the REV limmiter down from 6000 to 5600 will help the rods live a long life. We will most deffenatly find out :grin:
That much? I thought it was only 1500 or something. Anyways on turbobuick.com I read that someone had 1600 horsepower in their GN. It was someone I had never heard of before.
