Looking at 2.8L Kenne Bell Blowers

[Sirraf]

So, I am looking to get rid of my stock blower and add a better unit. I have done a little research, and I really like the Kenne Belle units. Especially the aesthetics, and the sound of the blowers. The deals on the 2.8L are pretty good. $4,999 with fuel upgrades, TB, CAI, and tune. That seems to be pretty close to what you could get a VMP kit for. Not to mention, it seems like thte KB units do better in dealing with heat.

Anyone have feedback on the Kenne Bell 2.8L? This will be for a 2012 GT500. Car is bone stock besides shifter and catback.

I should add, this will not be a track monster. I am only looking to make 650-700 whp comfortably and have really good manners.

What is the price difference between the 2.8 and the 3.2?, they both have the same external case dimensions.

With the 2.8 the production Super Snakes from that era (2007-2012) were in the 640-650 chassis dyno range, the 3.2 may get you a little closer to your upper number of 700?

I ran different 2.8Ls since 2007 and love them. Now they all have been on the smaller 4.6L block. As said above have you looked at the 3.2L at all?

 

[02GTKB]

I suggest going for the KB 3.2, it is maybe a $100 difference from what I remember. It will give up to 60hp more over the 2.8 boost for boost.

 

[CD07GT500]

If you want to buy a new blower and keep the car in the 650-700whp range get a Gen2 R from VMP. That is the fastest/cheapest option other than used blowers. If you are just dead set on getting a KB get with Van @Revanracing for the best prices on KB kits.

He will be at lower end of that range with stock manifold on pump gas. Gen2r and 2.8 are very good comps although I would take a 3.2 over the Gen2r all day long. That said I bet used gen2s are super cheap since guys are chasing gen2r.

I have that kit with the KB 75mm twin throttle body, a Lund tune, and 4.10 gears; originally bought from Revan & installed by the previous owner. I have had some interactions with both Van and KB over the last 2 years; both experiences were good. The 2.8 LC is a great kit. My car makes more power on 93 octane than I can use on the street, even with 305 drag radials. That blower isn't breaking a sweat with the 3.0" pulley I have on it (~18 psi). Driveability is excellent; like a stock vehicle. It howls when you get on it. People that have never been in a blown car are freaked out by the power, but especially by the sound.

Here's Van's dyno graph from a 2.8 LC on a stock 2013 GT500 running 93 octane and 18 lbs of boost. Stock manifolds and exhaust with an off-road H pipe, no internal work, not revving the piss out of the motor, and with a conservative tune. Stock lower, 3.0" upper (blue line). The red line is with a 3.25" upper. This kit is a lot older in release than most out there, but it is still competitive and really versatile (at least IMO). You can make a track monster out of it, or you can just run it as a street blower and it will do great. KB has a lot of info on their site..some of it is hype and bullshit, some is actually useful. I think if you call Van he will give you a pretty good run down of everything.

This thread will give you a pretty good synopsis of the KB 2.8.

I'd suggest you continue to do exactly what you are doing now-finding input from people that actually own these kits.

Nah fuel mods, JLT 127, X-pipe, cj mono, 2.6 upper with Gen 2 R will put him around 700sae on pump. With a 2.4 closer to mid 700s. It will also be faster than a 2.8/3.2 making ~700. Yes most cost efficient blower for 650-700 is a used Gen2 or trinity.

You know everyone is saying the VMP blowers are best bang for your buck. I got a package deal quote from both. Here is what you get and the price from both

Kenne Bell 2.8 package:
$5,299 tax and shipping included.

2.8L black (non polished)

You be the judge here. But for a 2.3L TVS blower with similar package offering, it should be nowhere near the same price as a 2.8L Kenne bell. Heck after taxes and shipping it might be more expensive than a Kenne Bell. Am I missing something here?

I wouldn’t waste money on a twin 67. Get a used CJ for $500. You can put a 2.3 R combo together for less than 5k and it will be faster than the 2.8 in the 650-700 whp range.

FWIW, I spoke to Jim Bell once, and he said, "To avoid the laginess of the blower (pump gas) stick with the 2.8, not the 3.2." That was a year ago.

Key problem with forums, is all the convoluted information from every corner, Ie, comparisons from built motors to altitudes, when trying to decide.

I had the same starting platform as you 12 months ago. Since I have an '11 w/ a stock 5.4, here is what you can expect from a Gen2R 2.5" upper setup ON PUMP 93 OCTANE.

There are everyday items that are posted in the classifieds you can pick up. Part of the fun for me is finding a good deal and avoid brand new pricing.
The classifieds and holiday sales are beneficial.

Heat soak issues; tune the car to 700rwhp and when it gets heat soaked, it will still feel like 650rwhp.
If a blower tuned is maxing out at 650ish, than by the time that heat soak settle in it will feel sub par 600.
Especially, if that blower is designed for a mid to upper RPM range! ​

[bcolor=transparent]Maybe someone can post up data with a 2.8 mounted on a stockish configured '11 or '12? You wouldn't think it would be that difficult with all the active hobbyists amongst us. [/bcolor]

Here is my graph. a 2.8 KB on the same tune won't break 630rwtq and be about 650rwhp​

[/bcolor]

Why would you run it on the same tune as a 2.3? A 2.8kb with a decent tune is more than capable of those numbers on an ‘11-‘12. It’s a capable/versatile head unit. Not saying it’s the end all, be-all of blowers, but there are plenty of guys running them with great results. You like the sound and the look? Buy it. Nothing else looks like a kB when you pop the hood. It’s a good kit. It will perform. Want to save money? Get a trinity take-off and call it a day.

I was in the middle of editing my post before I saw your response my apologies
In case, there is confusion.

On 93 Octane the 2.3 will produce better #'s and a better "Seat of the pants feel" than the 2.8KB.
I am not saying the VMP is the end all be all either.

But looks, and sound, yes the KB gets my vote

I've posted current data. Would encourage anyone to post theirs
apples to apples

 

[Handlebar Moustache]

Compare trap speeds and go from there. I agree that a smaller roots style blower will give a better torque curve at lower boost levels than any of the larger twin screws. Yes, the 2.8 will really shine with E-85.


quick search....

725 rwh on a 2012 with a KB 2.8.


Here's a guy with a 2011 in his sig...693rwh....only 17# boost...definitely 93 octane-safe boost levels. The 13-14's make 750 rwh+ on 93 with stock logs....

Nothing wrong with the VMP, but the 2.8s still crank it out and are still competitive.

Well for one the twin 67 is too small. You would have picked up ~25 going to a CJ/whipple mono alone. That combo will make 700+ on 93 all day long. Possible even ~750 without good fuel. The 3.6 is a waste unless you plan on turning it up on good fuel.

It was fuel not my TB that held me back since I was running 91. I was not interested in running a mono on the street regardless. The 3.6 on stock block was just a test run in anticipation of full build and switch to e85. It is much ado about nothing as 700 whp is as hard as I would run on a stock lower and you can get there a variety of ways none of which are blower limited.

You are wrong. Car would have still picked up ~25hp regardless of fuel. Smaller monos do just fine for daily status. The 3.6 is almost obsolete now with the new Gen 3/3R making 1100+.
