kennym01 said:KB blowers are designed to work with our stock internals if you stay within the 6-9psi range. No need to do anything else. Same with centrifugal chargers, if you stay around 8psi and are not putting out more than 400+ rwhp you should be fine. Do some research on the different types of chargers available. There's alot of good info on the net and on this forum. Try the power adder stangnet forum, there's some good information in there...
Actually, it's the pistons that bite the dust, not the rings. The mod motor pistons don't have enough meat around the ring landings which is where they let go when the pressure is on. I've seen the results of an engine that broke a ring landing with as little as 3psi of boost.svtcobra0304 said:I agree. Building any higher boost will put a little stress on the rods and rings. I believe the pistons would be ok though.

Here,I have the proof.
663rwhp 509TQ Vortech T-rim went 10.74 @ 130mph.
Same exact car,same track went 10.56 @ 128.6 with only 615rwhp and 577TQ..KB 2.2
He broke the trans and drive shaft on the next run.He was fairly confident it had a 10.30 in it based on the 60'........
I probably install more KB's then anyone.We have converted alot of Cen blower cars to KB's..The KB cars are quicker.
We had a GT with a intercooled Vortech making 415 rwhp and 398TQ..We swapped to a 1.7 and the car went almost .4 faster in the 1/4 mile with 400rwhp and 420TQ.
KB is winning hands down @ the track over the cen cars we have built.
G.I Joe went a full second faster in the 1/8 mile with his 2.2 over his 640rwhp Paxton blown setup.
We have the real comparisons..3 cars as a matter of fact..More to come......
You'll see a 9 second pass from a 2.2 KB GT as soon as the new tranny is in..This I promise.Based on the 1/8 mile time before we lost 3rd gear,its going 9's........It wil do it with about 50rwhp less then we had on the cen setup.

Was post number 103 not proof enough? Modular Ford Powerhouse sells, installs and tests both Centrifugal and (positive displacement) KB's and you just heard it from the horses mouth that the KB's are faster…and while making less horsepower at that! Seems like low end torque is of importance after all?......Or do they have to beat "your" centrifugal blown car for it to count? And even then, would that be enough proof? I know a lot of guys that share the same attitude and opinion as yours. Nothing can beat their set up and if it does, it was a fluke....of course, most of them drive Civics with neon lights and a big goofy wing on the back!noxious_mustang said:lol, and this is why i dont argue...proof proof proof....i just say when i kick your a$$ at the strip with my centri. dont come back with an excuse like my belt was slipping....no flames just an opinion....i have yet to be PROVED anything....

my orange-gt said:so if i go max out a credit card and decide to buy a supercharger which one should i get and what else should i expect to have to buy to support it on my stock o4 gt
cobra killer said:KB's dont just make low end tq..They make torque all the way up the powerband..The torque starts low and carries across..Alot better over all curve then a cen blower.The hp peaks just like a cen does..All in all,they just flat out make better power..
Blown00GTAuto said:Hmmm, this is getting confusing
I recall seeing dyno graphs of KB 4.6 GTs showing the power dropping off starting at 6000 - 6100 rpms. I've seen numerous dyno's of centri's where the HP continues to climb well beyond that ... even with my lil GT the hp continues to climb until 6500 rpm on a stock engine.
To site an example, there is a guy named Jim Fitzgerald who has a centrifugal 2v GT that ran 10.67 at 129 (automatic trans) with 544rwhp ... well below the 663 rwhp your T-Trim example made, or the 615 the KB example made.
It is my understanding that car's like Jim's do well because HP holds longer at high rpms, and can stay in a given gear longer (maintaining acceleration longer) vs. a car that peaks at a lower rpm. This is the advantage of the "top end charge".
It's odd to me that other guys have testimony that's so different than what you are saying. They're seeing in general that centris edge out the KB's in drag racing. .. and you're basically saying KB's are much better. There are so many variables that make our comparisons less alike than we might think.
Also, YellowJacketGT, a 14psi Vortech is not a direct comparison to a 14psi KB. The Vortech can run more boost (to get more power) with octane and intercooling being the same. And I would compare your KB 11.9 @119 mph car to the former 01BlownGT who had a stock long block 2v Vortech SQ running 11.6 at 121+ mph on pump gas.

cobra killer said:Jims Fitz car is sitting in my shop.He has an automatic....His car is also setup to drag race .A automatic KB car just went 10.40 @ 136 this weekend.Thru a 5 speed Jims car is well over 600rwhp.His automatic /convertor isn't telling the whole HP story on his car.
The KB doesn't just make peak power down low.It makes it all the way up..
Im telling you,every single car we convert goes faster.Jim Fitz is kicking around the idea of going KB.
I have built alot of 600-700rwhp cen cars...The KB flat beats them in every area....You dont have to believe me,thats your option..Anyone who does listen will be glad they did.
Check out this months 5.0..We have a 1.7 KB car we built that made 500rwhp and 605TQ.......It pulls all the way to 6500rpm..
The 2.2 pulls past 7000rpm..You'll see a 2.2 KB GT go 9's ver shortly with only 600rwhp and an automatic..Watch.....Its coming very soon.This car is a full bodied daily driver....Its already run a fast enough 1/8 mile to go 9's in the 1/4.We just have to fix the tranny issuse.
Look,I sell and build turbo cars,cen cars and KB cars..I have nothing to gain either way.Im telling you,the KB cars are the ****...You just have to experience one.
