Kennebell

usaf_branham · Jul 17, 2009

Ok, so after driving an 03 cobra today, instead of trading my 04 gt in on the cobra...

I have decided to buy the intercooled Kennebell for my car...

I have already put BBK L/T's on my ride and 4.10's. I already know im going to have one hell of a time trying to get any kind of traction after the blower is on. But hey, I am sure I will be having some serious fun.

If any of you have run a set up like this, what kind of numbers am I looking at on the dyno (with a good tune). When all is said and done the total mods will be...

Intercooled Kennebell w/ 9# pulley
BBK L/T Ceramic Coated Headers
BBK H-Pipe w/cats (im currently running an o/r x-pipe with flowmasters and i dont like how it sounds, plus now i have to worry about emissions...)
Flowmaster Cat-Back American Thunder Exhaust
FRPP Alluminum D/S
FRPP 4.10's on a reworked diff (new clutches f/s/f/s, shimmed tighter)
Jack Roush Classic Short Throw Shifter
Dyno-Tuned

I have the BBK Cold Air Intake on it, but i dont know if that can be used with the Kennebell...

Any comments or advice on what im about to do would be great. Thanks.

Around 400-415HP at the wheels. You don't want much more than this because it risks overstressing the stock powdered rods and hypereutectic pistons.

FWIW, a "good tune" with a blower on a stock-internal engine is a tune that sacrifices a bit of peak power for safety by running fat and pulling timing to reduce the tendency to detonate. I might see another 25HP if I re-tuned mine (running KBs chip now) and pulled some fuel and added some timing even on the stock manifolds and stock H-pipe. However, because mine's stock inside, I'm okay with giving up some dyno numbers for daily-driver reliability and safety.

A fast 4V is cool, but a fast 2V is badass!!!

Great Idea!

I have pretty much the same except no long tubes. Although you will get the 2.1L
Kenne Bell, I was probably one of the last to get the 1.7L. But at 9psi it doesn't
matter to me. It's fun to drive. I haven't gotten a dyno pull on it, but I'd say I
am somewhere between 375 to 400 rwhp. The Kenne Bell tune works excellent
for me. I have over 12k miles on it now and no problems.

Yes, the BBK CAI can be used with it, but it's tight and you have to slip the joints a bit to make it fit. I had it on before and wanted to have it on after as it looks
nicer than the stock black plastic tube.

I have an 02 gt with a 1.7KB. Stage 3 blower cams, titainium jba headers with 11lb pulley. Pulled 438 rwhp. Have been running this way for 3 years now. Get a good tune, makes all the difference.

BLK_ROUSH · Jul 18, 2009

Agreed ... the 400rwhp target is pretty easy with the above listing.
As with any FI set-up the tune will be critical ... but you will really enjoy the new found power.
Won't forget about that Cobra until you get built. Then you'll be looking for those Cobras.

So there have been some changes to what I am doing.
I just started the Kenne Bell tonight. So far I have the manifold off, and all the parts removed and labeled. Due to my budget, I welded on a set of catco universal cats to my bbk o/r x-pipe. Which by the way, completely changed the sound of my ride. Its not as loud, and actually has a bit of a deeper tone to it. I dont have to crank the radio now either. heh. Any way, I am still having Big Shot Dyno replace all of my header studs with stage 8 locking fasteners, I did the l/t install, but I have 0 ambition to **** with that again. I am leaving my 4.10's in there for now, at least until I sell my predator, then I am going down to 3.73's. Hopefully one day I will be able to get to the uca's and lca's replace them with some good aftermarket ones. I was told by Big Shot Dyno that I am going to need put a mafia in it, which i didnt expect. So after the blower, dyno tune, mafia, and sct switch chip, I should be looking good on numbers. Im guessing any where from 400 to 425 rwhp (safe). The installation instructions from Kenne Bell are awesome. It reads like a T.O. except more detailed. I am honestly impressed.

What's your elevation?

I'm at 6,380 ft. above sea level and I only get 6 lbs of boost from my 9 lb pulley. That has me down around 350hp on my 1.7L intercooled. I think you will be happy with your setup. You can always tweek it for what you want.

I was running a diagnostics device (can't remember it's name but it's like a tuner but you can control the car from it) on my car in auto class and at idle I could see the timing jump from 15* to 24* and back. That was weird. Is it supposed to do that on the Kenne Bell chip? (Not to highjack but I think it's related to any KB thread).

SCalla1384 · Jul 31, 2009

Damn I wish I could just go buy a Kenne Bell like that lol. Anyways thats awsome man, Kenne Bell is so sick. Like others said you should see between 400-425rwhp.

LoL 4.10s with that is gonna be rediculous. Youll need some suspenion mods to keep the power to the ground so your not constantley wheel spinning halfway or all the way through 3rd.

Keep us posted with some pics and vids man, remember get a good tune.

usaf_branham · Aug 1, 2009

well, i just got it done. now i have to wait until monday for the tune!!! do you have any idea how hard it is for me right now. i want to go tear some tires up, and i cant... the install went pretty smooth it took me around 18 hours or so. unfortunately my a-pillar with guage pods isnt going to be here until tuesday. so im going to have to wait until then for my boost guage and fuel pressure guage. the only 2 things i didnt care for with the install was, the intercooler brackets are a pita, and the directions arent very good for it, also the directions for the boost-a-pump were minimal. other than that i have no complaints.

usaf_branham · Aug 1, 2009

do any of you have a diablo tune for the predator that will work with the kennebell at 9 psi and 36lb injectors? it doesnt need to be spot on, because its getting dyno tuned on monday. i just need something to get me 20 miles to big shot dyno, with out having to trailer my car.

Gearbanger 101 · Aug 1, 2009

You'll probably see somewhere in the 380-400rwhp range with the 9psi pulley. I'd think 400-425rwhp is being pretty optimistic....especially with only exhaust mods being the majority of your enhancements.

In any case....it'll turn your car into a whole different animal. I can't see you not loving every minute of it!

Big Shot Dyno did my tune and install of my blower. Keith is an great guy to deal with

Why don't you just head over early and change the injectors in the parking lot? That's what I did with my 42's. It took me all of half an hour. The engine will be fine with the blower on there provided you drive it there under vacuum and keep your foot out of it.

Indeed. I don't know about his KB kit but mine has a "valet mode" on the bypass valve. A small setscrew can be adjusted to hold the bypass valve open which prevents the blower from creating boost and making it safe to drive with the OE injectors.

Once the injectors are in, he can re-set the setscrew, get it out of valet mode and get the tune done.

Learned something today ...... thanks.

Just be careful and not get greedy. I had my KB installed with the KB chip, intercooled 9lb, boost a pump and mafia. Car was great with the 382rwhp.

I wanted 400 , so we downsized the pulley, put a 75mm TB on and retuned at a dyno shop. 419 rwhp was what she registered.

Two months later I went to Rockingham to run the 1/4 mile. First pass of the day, threw a rod and made a 4" hole in both sides of the block.

The bad thing about the twin screw is that if catastrophic failure happens...it can ruin your SCer too.
Pieces of piston went up into the intercooler and found their way up in the rotors. I had to pay KB $1000 to fix the mess.

Brightside is that I got a fully forged aluminum engine out of the deal. Cranked up the hp even more with the 14lb pulley and its sitting on 471 rwhp now.
Moral to the story... Be careful on those weak ass rods.
