Whipple 2.3 all the way. Bigger bearings

here is another quote from you on the link to the KB 2.6 vs. whipple 140ax thread
link to thread: http://www.svtperformance.com/forums...d.php?t=321256

I went from a whipple to a KB. I like KB's better and always have. Their performance is very alike which makes them both very competative. The KB's sound awesome so thats how I really fell in love with KB's. The 2.6 is better imo bc of the more efficient big bore. Its newer too, so thats why I would give it a shot.

2.8 is a waste of $$ unless you're cammed and ported ect.
Has to be a heavy breather or race car.

How do you figure? The 2.8L has thrown down great numbers on stock displacement cars and even 2V engines. Seems to have more top-end pull than the 2.6L blower. Not saying it is necessary, but I don't really think it is a waste.

I like my 2.4, but I have seen some whipples run very good #'s as well. If I were to buy new and the 2.8L wasnt on the market I would go with a whipple 2.3

I got my 2.4 used for a steal, otherwise I would still be 2.7/4 Ported Eaton & 100 shot laying out twin screw cars all day long like I used to

with that procharger your talking about or the tubro either one. that damn car would not a daily driver you would need to **** with it all the time. :poke:

Procharger and ALL Cent Blowers make too much noise for me. I chose the Whipple because they were MUCH easier to deal with than KB. BTW, with a properly tuned turbo kit you NEVER have to F*&K with it. :thumbsup:

I've got a KB 2.2 with cams, and make 670+ to the tires. I've never had a single problem with my KB at all. I've never owned a Whipple, but I would highly recommend a KB any day of the week. ESPECIALLY OVER A PROCHARGER........dont even get me started on this piece of engineering marvel. lol

How is your hook up? What other mods have you done to get 603rwhp? Did you do the injectors, boost a pump etc..? I am looking to get the Whipple myself in a month time. Where did you buy yours from?

Thanks

im still not sure why people insist on saying KB is much better i know of a dozen whipple and Kb cars that put up right around the same numbers. If your running over 650 at 18lbs of boost even with a conservative(perfect) tune your asking for a short life. Either way both are terrific and are capable of producing the same hp and tq on a safe level. However I do believe if you like risk and a car over 21-23 psi of boost kb has a slight edge. But for safety and price whipples my choice.

I love my Whipple, made 625 on 17 psi. PLENTY of power for the street which is what my car is for. I'm sure you can't go wrong with either.:coolman:

2.8L

Lower IAT's. More power with less boost and less power to move the rotors, they are spinning slower.

Plus you will have all the room in the world to grow later. They are keeping up with heavy modded turbo setups.

Always better to have to much than to little.

Keeping up with heavily-modded turbo setups? Umm... do you have any specific examples of this? Stock-engine turbo setups have run into the 9s. The HPP car is probably the best example of that. Haven't seen any similar KB setups anywhere near that. Would certainly love to, as I plan to upgrade my blower next year!

Here is two examples:

http://www.modularpowerhouse.com/forums/showthread.php?t=43357

JW's 2v will most likely be in the 9's. And go to post #16. Jim is @ 9.47 on all motor, no NOS.

http://www.modularpowerhouse.com/forums/showthread.php?t=43237

Not exactly stock internals but in all means a 2.8L KB can keep up to turbo monsters, and these are 2v cars. I would find it rediculous to build a 9sec TT to run 9's with stock internals. If one is going to play, build it right. A pos blower does put a MUCH bigger stress on the internals as Turbos.

This is a mute subject a properly setup turbo car will kill the similiarly setup blower car.

A full full nasty built turbo setup like something from Nopi, yes I agree. But your typical TT or T setup everyone is doing no. These KB 2.8's are seeing 800-900rwhp, oh and these are only 2v motors.

TT and 2.8L both have advantages and disadvantages. All im saying if you had like a HPP TT setup and you lined up to a properly built 2.8, I wouldn't bet your pink slip.

Again im not saying they are better then turbos, but they are running with them. The whp and ET's are on the sheets, this is not hear say.

Let's not ruin this thread on a debate of turbos against the 2.8.

But if I was about to spend the cash on a new KB, I wouldn't think twice and get the 2.8L. Just one mans opinion. I have been down the road of wanting bigger later, it sucks, especially for your wallet.
