Kenne Bell 2.1L

[ASH302]

hello there, so anyone know if the and how much boost it would take for a KB 2.1L to push out 625 to 650rwhp??? also can it do it without over spinning the s/c???

this also would have a intercooler too on with it,

why i ask about the 2.1L is cuz TRmach told me on the 2.2L and up you would have to do alittle more modding (which means more money) and the 2.1L is a direct fit and KB sells the Kit. so that is why i would be going with a 2.1 over the others.

ASh, I don't think that all by itself the 2.1 can push those numbers out. It would take some sort of secondary effort to achieve. Mine did it, but that's because it had a 100 shot of nitrous helping out! In addition to the blower, it would probably take either nitrous, or meth injection, or race gas, or some kind of combination of those things to put down over 625rwhp. Kenne Bell says they have a 21psi pulley for the 2.1, but I've never seen anyone ever push one beyond 18psi, and it gets pretty hot! Mine was tuned for 16psi, pulling 17 degrees of timing, with a fairly rich a/f mixture on 93 octane, and by itself put down over 527rwhp. Leaning it out some more, bumping the timing up to maybe 21 degrees, and going 17 or 18psi, it might see high 500's, or low 600's, but that's on the ragged edge, and not very practical for a street car.

The KB 2.2 on up, are all meant for Cobra-type applications, so you would have to do a full Eaton swap to make them work.

How well would it run if running E85? I know E85 responds well to FI.

I have absolutely no clue! Here on the East Coast, we don't see very many E85 tuned motors!

thanks TRmach, yeah the reason after you said something bout the 2.2 and up having to do some of the eaton swap thing i was like NOPE, lol just don't want to be spending a azz load of money for s/c stuff unless needed and the only reason i would switch over to KB is that if i could get it straight trade or maybe alittle out of pocket for something. but that does answer somethings, i'll still need to think about everything, do some more research nothing i'm in a rush for. also i'm going to be fixin the idler pulley starting tomorrow or sunday sometime soon and get that all fixed and who knows i may just not mess w/ looking any more doing a KB s/c. we will see.

thanks again for explaining though

Ironically Kenne Bell used to have a 2.2 for the Mach along with a 1.7. I bought the last 2.2 KB years ago. On 9 lbs of boost and a stock motor I was just short of 500 to the wheels.

Not happy with a centri anymore?

that must have been nice with little boost getting that much HP, very nice,

i wouldn't say that, i guess i'll go ahead and put down why i'm wantin to switch. like i said before once i get everything lined up and good to go. do a stronger tensioner, and prob go to 8rib i'll prob be fine with it and not even mess with going to a KB.

so hear is reasons for wanting to switch right now.
-it seems to be less maintance with KB/whipple compare to centri
-power seems to be better with lower amount of boost with KB/whipple
-less stress on the motor
-better gas mileage

-Dont see how you come up with that yours and those are self contained no maintance other than oil changes
-Torque is stronger in the lower boost total power alot of varibles come into play IE tune, boost level.
-Twin screws require more power to turn than centri's.
-FALSE thats all in the Tune.

also if your going to go with a KB id go with the 2.6. the 2.1 will struggle making the power your making now maxed out.

The reason i was saying the 2.1 is that they don't make a mach kit for the 2.2 and up. which i would be spending way more than i wanted to if i went to this change up.

keep em coming guys

the Mach 2.1 runs off the stock belt system just like the D1.

the KB's make more TQ down low yes but racing when your RPM's dont drop below 4500 TQ the centri and TS are going to be a good race HP for HP.

My buddy has an 02 GT with a 2.1 KB and its a blast on the street they are great street blowers, I personally like centri's more.

i understand what your sayin and i think has there way of what they like so its all good. like i've said before once i get every good on the procharger than i'll prob won't switch, but the case is still open and have time to figure out everything,

so here is the update on this subject, after having alittle more time to take in what everyone posted and also alittle research, this could be the master plan. well once i get moved, i look for someone that would want to trade me straight up for a eaton swap kit, or find one and buy the eaton swap kit, once the eaton swap is install and everything checks out, then sell my Procharger D1sc kit. with that money i'll buy me a Whipple (that would be my first choice) if i end up finding a Kenne Bell i'm wanting 2.2L and up. but no matter what i want to keep the shaker on there,

this stuff above is if all the stars are line up and my procharger keeps pissing me off and then i'll just go ahead and do the swap to the other one.

ok now here is prob whats going to happen, more of a chance, the procharger will finally settle itself down and got the belt prob fixed, i understand that a belt is going to get worn out when pushing alot of boost, but it should take it alittle time and that is fine with me, so then what will prob happen is i'll get the thumper RRR tensioner for it and then i'll see how everything goes and then i may just upgrade to a 8-rib set up and that should help alittle more on the belt. this would be the least expensive way to go about it, but i'm thinking this is going to be the door i open up when i get to that fork in the road.

who knows the other may come, there are diff reason's why i'm wanting to switch over to a whipple or KB and they are pretty good reasons, i wouldn't say its for sure not cuz they are more bad azz that procharger, like i've said i love my procharger, just would rather work smarter not harder and have stuff last alittle longer before new stuff have to be replaced

[ASH302]

also by switchin up i'm not looking at making really any more power, i for sure don't want to have the mach feel less powerful, so if the numbers on the dyno are alittle lower but it performs the same if not better than i'm happy, but my goal is a around 600ishRWHP when we are done and also around 550ishRWTQ, like my tq and hp numbers to be close

I was beginning to wonder if you were going to pipe in on this, Scott. Because for some reason I thought that you had the 2.2 a while back. Must have read one of your posts on it when I was researching or something...

I have the intercooled 2.1 KB/big oval TB and like it a lot. In the beginning I had some issues with the tensioner and the set up separated my stock crank pulley.

To remedy the tensioner issue, I simply lowered my shift light RPM to help remind me to shift earlier (6,200 rather than 6,500/6,800). I do still always carry a spare belt/tensioner in the trunk...

For the crank pulley I replaced the OEM piece with a Summit 10% over pulley and it has been solid for about 20,000 miles now.

As for power - I'm still on the stock motor and am at 8psi. With 8psi and not too much timing (I don't remember the degrees but remember the tuner saying it wasn't very much and how he was surprised with the power) I'm at 475rwhp. We had it up to 500 with more timing but brought it back down since I was more interested in reliability than a few more ponies.

If the engine got built and a smaller pulley added to the KB, I imagine it wouldn't be all that difficult to get a bit more power out of it. I'll probably never know as I'm happy with my power level as it meets my needs for autoX and driving style.
