Fully built motor with a supercharger.

[TRD_07]

Not sure if you were only interested in Vortech or twin screw applications but KW will eventually offer a stage II which should place you within the numbers you're looking for.

Honestly if I were to do this, I wouldn't go with any of the current out of the box kits being offered. There's also the c38 rotrex (Kraftwerks says they have an upgrade path for this) which is a bigger unit than in the Jackson & KW kits. There's also an upgraded sprintex blower if you're looking for innovate route. And, there's the Vortech oil fed unit which is said to also have a higher redline.

There are Vortechs pushing 350-380whp on e85 (@charged86) but to my knowledge they are also all overspinning the blower which is likely to reduce its lifespan. If you're looking for reliably doing 400hp with a supercharger I'd go with an upgraded blower for this reason mainly. Also proper cams + higher redline (if possible) I would think would both greatly increase performance of a centrifugal.

I'd also love to see your build in action . A S/C 400whp FRS would be killer. And I don't think its necessary to go turbo you just need a bigger blower.

I thought it ridiculous how Matt was also still getting driving problems with the car. Really? If a customer puts that much money into their car I would be pissed if I was getting driving problems like he was explaining.

It's more the size of the blower itself that is the limiting factor. It just can't breathe enough to support 400whp. I think the 300whp area will be close to the max you will see from the Innovate kit with the stock blower. Sprintex does make a larger blower that will bolt on to the manifold, but may or may not fit in the engine bay with the stock hood.

Thanks Ill do some more research!

Hopefully in the next month Ill be makeing some more purchases.

If you want S/C for the sound your not going to find the whine one any non-root style blower. Pretty sure nobody has hit even 300whp with the innovate kit yet. (Probably wrong)

Why Crawford gets no love in this forum?

Because a turbo kit is not a supercharger?

Because I haven't seen a single member on here purchase the kit or show the dyno results or a build thread.

They aren't even selling their turbo kit yet either...

And correct me if I'm wrong but most of their kit seems to be based on their low compression build/parts. A step most of us don't want to do until the stock block gives.

[EAGLE5]

Looks like they have delivered 4 so far:

In another post dated October 3, they said they're on the final leg of making 10 kits.

I think the full build is overpriced and the old videos showed what looked like a poorly tuned car. I think Crawford wasn't tuning it themselves. That being said, they also make some great stuff.

$$$

Only thing that got my attention from crawford was that they are selling a complete long block ( Built ) for about 7 grand which is think is not bad

Down there page they have another picture of the car. @APRil 28th.

"Crawford Street Edition FRS #001 leaving the building! — in Oceanside, CA."

comments section they posted:
"The tire size is 245 and 265, wheels are 8.5 and 9.5, zero engine mods, Crawford AOS, K&N air filter, lowering springs, front and rear sway bars, Crawford Gymkhana axle back exhaust, graphics package and serialized billet Crawford Edition badge."

followed by...
"Thanks Walter... time will tell how the rest of the world reacts to our Crawford spec cars"

There's also someone else who recently hit 360whp with the Vortech on e85 as well, that dyno and more info is in the Vortech questions thread.

The 360WHP was me. And I did this with a factory exhaust, factory header, factory cat, and a slight pulley upgrade. I am not even running the smallest pulley i can. I still have another step up before i hit the limitation of my self oil-fed supercahrger. Vortech does however have a "race kit" that uses external oil supply that can spin at a 20-25% RPM.

^ This. Go with Vortech or KW. Both of these kits have "upgrades" that are direct bolt on to large blowers. The vortech is an oil fed unit that can rev higher. The KW is a larger rotrex unit that has a fairly high flow rate.

I'm excited to hear that people have made over 300 with the vortech kit. I've completely missed those threads. I did see the one with the hks blower a few months ago that someone linked here.

^this again. There are at least 2 vendors that tried to make power but were unable to produce more power after a certain point. The twin screw efficiency range is not like a turbo or the centrif superchargers. It just falls off at a certain point and over-reving will only get you so much. Which is quite unfortunate because damn... those inovate are a lot of fun! But even with their fun they have their own issues.

I am not over spinning my blower. IIRC i am spinning at roughly 40-42k and the bearing setup is rated for 50k.

If i were to put a full exhaust, high flow cat, and a proper header to rid of that wonderful cat up front and put on a 3.00" pulley with a stock redline... I am fairly certain I would be in the 400's. However keep in mind this is on E85, not pump gas.

You haven't seen my thread as I have kept quite while testing things. I had fair number of issues while testing my setup and making changes over the months. However all the manufactures I have worked with have all made changes and resolved the issues. I am switching back to pump gas for further testing here soon and once I am finished and finish with all of my dynos comparing boost levels, fuel types etc I will be posting my experiences & dynos with my car and other FI setups I have driven.
