I was at the bookstore today and picked up a copy of MM&FF. There is a huge like 10 page article on the KB/JohnnyL blower. If everything there fills out, that blower is pretty sweet!

Straight bolt on, it gets a 50hp increase over the stock eaton (and runs at ~13psi). The article said they had it up to way over 20psi on a stock block (with a 6lb lower and 2.5" upper Autorotor pulley)...while that is a bit too much in my opinion on a stock block, they ran their pulls. I'm sure it would throw a rod at that pressure over time...the amazing thing, the INTAKE TEMPS! At the max PSI, the air temp coming before the intake was 320, on the other side? 106!

They pushed a total of 520hp, 600tq out of the Autorotor with a 90mm MAF and some sorto f jobbie for the intake...they said the plenum became a restriction at over 420hp (it showed vacuum).

They had a ton of test equipment for this test, and showed all their graphs...that blower definately looks like a nice package, I imght have to pick one up in the future... I just wonder how it sounds? What did JL's truck sound like in FL? Because I love my Eaton whine.

PS
Just FYI, I'm don't carry a vendor bias, I try to keep myself in the objective product wise... Sal is a friend (and will hopefully be the builder of my engine in the not to distance future), I've met Jim a few times and he's going to be doing work on my truck next week, and I've had dinner with JL a buncha times...all are nice guys.

 

 

I was at SDR and heard JL run with the KB. I couldn't hear the s/c over the 3" exhaust pipes--no cats or mufflers. JL said it was too loud for him and the Basanni was going back on.

With mufflers, on the street, I would think you could hear the KB....

Yes Boost will kill a engine cause it happened to me. My engine broke rods and threw them out the side of my engine. It was not from a bad tune or detonation its because the stock rods are to week to handle any more power. None of my pistons showed any sign of detonation. Its just a plain simple fact if you want lots of power you better have a built engine to handle it.

 

I was just talking to my buddy last night and he's been going back and forth with different blowers on a mustang anyway. He's had the novi 2000 on his car and the vortech YS trim last time they dynoed and this is what happend which seemed strange to me.

the novi 2000 on the car made 796 hp at the rear wheels at 28 PSI. the vortech YS-trim made 797 hp at the rear wheels at 20 PSI. After him explaining this to me more and more I guess the effieciensy is the most important part of the blower and I would assume that the new KB blower is going to be more efficient then the eaton and run less boost pressure also. I get lost sometimes when him and the other guys get going about boost and pressure and all that stuff, hey I'm new to this stuff I'm still learning.

As for me, I am biased to PSP but I'm going with a Vortech YS-trim now, the novi just lost my vote after that dyno run.

 

Because they were pushing MORE then 20lbs. I couldn't remember the number, but I think it was 28.7 or something, I didn't want to put it down without remembering what it was. You go run 30lbs of boost on your stock block, its your perogative. I'll upgrade mine before I do....matter of fact, I'm upgrading my tranny before I even get to the engine first.

REALLY???? Were you exceeding 5250RPM? Where were you shifting at? Where was you rev limiter set at? What boost level? How often did the engine ever exceed 5500rpm - even before you added the boost? There are only so many revolutions the crank/rods can take the higher loads brought on by higher RPMs. Please answer all of the above questions.

 

Air Charge Temperature is a direct correlation to efficency. The better the efficency, the lower the Air Charge Temp, the more power, thus less boost need to make the same power. Then there's the VOLUME of air being moved that makes a difference as well. Different "trims" will yiled different efficency curves at different flow rates. Wanna get lost, just start looking at turbo flow charts that do nothing more that grapg efficeny, volume agains trim size.

Youu can make 8psi with a top-fuel dragster's blower or 8psi with the Eaton M112. You can make 20psi with both... which do you think will have a cooler air charge thus more power?

 

Bingo thats what he was talking about last night!

 

How can you even make 30psi

 

Thanks, i hear that all the time

 

Has anyone seen the June 2002 issue of MM&FF?

The new Kenne Bell Autorotor is tested. 522 hp and 600 foot lbs of torque at 21.6 psi

Wow! The scarry part is that a stock bottom was used!!!

Those are some promiseing numbers...

but with those numbers I expect a rod or two to let loose real soon, if it hasn't already.

 

I just had a thread about that 2-3 days ago. It sounds really sweet, but I also would not want to push 21psi through a stock block

 

Can someone scan the article
