Yeah, it will absolutely suck ***** with the stock kit and you are better off getting the upgraded kit / setup. Then again, I'm not a big KB fan. Never cared for the twin screw blowers. Instant power can be a good thing but it can also be bad. Plus it's not quite as easy to keep them cool. I prefer a nice little centrifugal blower

And given how cheap you can get a GT40 lower for... I bought an entire turnkey Explorer engine for $350. That was a great deal. I sold the intake and heads but still have the rest of it. Looknig around locally, gt-40 lowers are dirt cheap and are well worth the upgrade price. You'll regret it if you stick with the stock route.

samseed how'd you make out hp wise with that explorer build? or are you still building it?

FivePointOhh

if you end up gettin the KB let me know on performace because i hear so much different info on if kb. it gets too hot, lose power, its awesome power all the time. i dunno im so torn if i should get one or not when it comes time, i love the sounds and the website make it look insane.......but then again you always hear different

I was at a car show last night and a local guy with a 90 notch has a gt-40 crate motor with a rebuilt t5 tranny amd he installed a KB 2.2 onto it this past spring, he had a lot of dyno tuning to do, but he says it pulls hard all the way from 1krpm to 5krpm... granted his motor and tranny are brand new, 1 year ago 2500miles, but he has a monster cold air intake and a 90mm lightning maf... i suppose it's all in the tune becaue i've heard mixed reviews in the past also. He rebuilt his car from the unibody up... every single piece...replaced/refurbished/repaired... this car is cherry!

Lol,. it never even hit the dyno. I got it toget er and put about 2 miles on it during the winter. Never got on it hard because it wasn't tuned. Then I realized that by the time I was done, the increased power would require me to get bigger injectors (again,) a bigger pump (again,) a new stroger tranny (again,) would need to get the elbow adapter, a new intake spacer, new strut tower brace, and I forget all of the other stuff but it was a huge list.

In the end I decided that I was going to pretty much place it back the way it was, minus a few changes, and keep teh power levels down to where they were before.

I ended up keeping the Steeda #19 camshaft installed because it was too much effort to take that back out. I also did end up putting in a 255lph pump anyway. But the stock heads and intake went back on (after being cleaned up slightly.) I also put a blow through 76mm MAF on there to replace the stock draw through that was pegging anyway.

Before the swap I had 320rwhp on the blower, 430 on the bottle. Not sure what it is now but I suspect it will be slightly higher due to the better MAF, cam, and tune via the tweecer. I am also working on adding a dry stage to my existing nitrous wet kit so that I can spray it right off the line for a little extra boost. That's not even close to completed yet, as I need to figure out how I am going to do it (either before or after the MAF, depending on some other factors.)

But that's my story on that. I sold the intake for $200 and the heads for $250. I still have the rest of the aprts in my basement. If anything, I think I am going to stroke it to a 347 and sell it or toss it in a junker in the near future.

The KB will get hot and lose power over time as it gets hotter. You can see this on a dyno after several runs. Also, icing it down doesn't have the effect you'd expect. They are good blowers, but they can't deny that one problem.

+1 i agree dont was cash on TW, Innovations makes great cams too

yea if u can find a cheap cobra it might be worth it... the lower will work on KB

The Blowzilla only comes with the GT40 style runners.

where would I find the canfields, i was leaning towards the afr's cuz i couldn't really find anywhere to buy the canfields, but if those are better, maybe i'll go with those...
