Been thinking real hard...real hard...I'm gonna skip the ported route...If I can improve some more on my track times, I will step up to the bigger blower as my goal was to become above average with the Heaton at the track and then upgrade...
Been highly considering the KB 2.2 and the Whipple 2.3 Gen II and the Whipple 3.4.
If I go with a KB 2.2, if I can find one, I will get it rebuilt to make sure it's good to go.
But I have been looking for a few months now with not much luck. As of now, I'm leaning toward the 2.3 Whip, but I was hoping you guys could help point me in the right direction, so I don't regret my decision. I have always liked the way the Whipples looked on the Terminators versus the KBs, but nothing beats a KB 2.2s scream...
Give me some input guys, as my goal is to have an approximate 600hp street/track monster that should be able to hit the 10.**s
Thanks

Go big..and get a whipp.......You will always want more...trust me and everyone else that says it....grow into your mods..not out grow them...

The KB 2.2 was great back in the day...its small, the inlet is really bad....and the screaming is great however,....the reason it screams so well is that its causing alot of heat (air movement rotor design.)....hence killing your IAT I and II's. trust me on that...

Get a whipp 2.3 or the 3.4...and do the intake upgrade by all means...you will be ever so happy....Good luck man...Keep us posted!!!

real men go whipples and turbos. kenne bells breack way to damn much

Gen 2 2.3L Whipple is what I'd do, depending on what you can find a 3.4 for. I'd still probably go for a 2.3 if you are going to only want around 600 WHP. You can easily make more than that with 23PSI and a Behemoth inlet, though.

Well Hunter, I remember you talkin about your next upgrade, Why dont you sell him your whipple? lol

Hmmmm...................................................

Too bad I'm not ready right now...haha

ah hell... it aint nothing but some bolts and some dollars... man up... lol

The whipple 2.3 is a really good bang for the buck blower, new or used. Not a selling point but it would also match your ice box better than a KB

It's similar on cobras as it is on lightnings. The 3.4's are meant to shine where a 2.3 can't and thats boost above 24psi, which is not something you'd want in a daily driver or a street car like you have that's the weekend warrior. A 2.3 would be more than enough 18-20 psi, you'd be right at 600 ish and no reason not to run bottom 7's upper 6's. However, it's just not the cost of the blower, you will be upgrading or replacing clutches, input shafts, fuel system, half shafts.. etc with the extra power. Ask Cullen, he waited 6 months to put on his blower, upgraded everything first then when it was time didn't have any things left to do besides cooling mods.

If I had a cobra as my only toy, it would be a TS car for sure. Maybe a turbo if I had a nice Daily driver that was still fun, like a lightning

That's the absolute best way to do it.

A 2.3L at 22-23PSI with a Behemoth could make quite a bit more than 600, too, so you aren't locked into 600 as a power number if you aren't scared to throw a little cash at it.

3.4L all the way.... Less heat = more power... After many passes at 22lbs in the dead of summer i could lay my hand on the blower... Heat kills

notching your hood FTL not to mention possible broken crank pulleys! I think I am going 2.3 whipple.

If done right..its nothing major..and the crank pullies are few and far between.....I had lower crank pulley problems..with an eaton....Our site owner Nakea..has a 3.4..and the install is super clean....Notch in the hood ftw....

Listen to people who have and used twin screws.....

Hood is not bad at all.. Crank pulley beaking because of 3.4...... That would happen with a eaton like cullen said.. It the aftermarket lower pulleys that have the problem...

I wouldn't want to notch my hood, don't care if it was done right or wrong, still a hole in the underside of the hood that wasn't there before. To each his own.

No I don't have a twinscrew but since I don't have one I don't know what I am talking about? I guess I am going to stop giving my opinion since everyting I say is wrong....
Sorry for the hijack...

Great info guys...very good read...
With all the great input...I am steering toward the whip 2.3, but is it true that the 3.4L at same boost levels as the 2.3 will not yield the same power?
I would hate to buy the 2.3 and say, dang...should have gotten the 3.4....b/c I know there are a few 3.4 DDs out there who swear by them...
One more thing...when I see the 2.3L for sale, they have 2 different kinds, one for the stock throttle body and one for a 100mm throttle body...can someone expand on this? pros/cons

One is for the aftermarket t.b's and one is for the stock T.B.'s.....either way...whipp 2.3 or 3.4..you can't go wrong...

2.3 or bust at the boost level you want. 3.4 will make the same power as a 2.3 but seems to have less of a meaty torque form the dynos i've seen.

The crank issue comes with the massive amount of torque that the 3.4 uses and creates. It pulls at a right angle to the crank and over time can weaken the snout and cause it to break if you are running a VERY tight belt and a lot of boost. If you keep the stock lower (I would), you'd have no issue at all. The lower pulleys have been known to break with most anything, not just a 3.4L. However, considering the number of lower setups that are out there and the number of breakages we have seen, I'd say it's not a huge deal.



Don't take this the wrong way, but a lot of what you read on the internet is just plain hearsay. You have to make sure to take a lot with a grain of salt because some of it is just plain misinformation that can cause you to make bad choices when choosing a setup for your car. I learned a lot about this when I went twinscrew (and even ported) that I would not have known had I not actually done it.



At a lower boost level (20PSI or below) the 2.3L will be your better choice by far. The 3.4L is a great blower, but it will really shine past the boost level you are wanting to run. If you are wanting to stay moderate with the boost, 2.3L will be just fine for you. I love mine.

Whatever you do, buy the SBTB Whipple inlet plenum. You will be kicking yourself if you don't. The stock throttle body will only flow about 900CFM, and the Accufab SBTB will flow 1500-1600CFM. A 2.3L Whipple with a 3.5" upper and a 4# lower will be flowing 1297.259 CFM. The same blower with a 3.0" upper and the same 4# lower will be flowing 1513.47 CFM. Just some food (or math, in this case) for thought. So, as you can see, the stock throttle body will be a restriction for you if you run anything over about 15PSI.

I understand how to take info on the web, I don't post BS info the only thing I was a bit wrong on was the pulley breaking which I know about the stock idlers shattering etc. I posted about notching the hood and said I wouldn't want to do it to MY car. I do a lot reasearch and ask questions, before deciding on a mod myself.

He asked about bigger blowers and mentioned the 3.4 so I gave my opinion on the bad part of the 3.4, again I apologize for the hijack sorry if anyone thinks I have an attitude was just trying to help him see all angles.

He should buy my spray and be done with it is what he should do :O
