Karwerkz E46 M3 Blisters the Track at MFest 3 (Race Footage)

[HPF Chris]

Congrats to Oscar Tevizo (owner of Karwerkz), Evo (his driver) and his amazing Asuka Design Widebody M3. For anyone that had doubts about what the E46 M3 could do with a turbocharger on the track, click the videos below to find out just how well the Karwerkz M3 did against the competition in the advanced group at Spring Mountain Motorsports Ranch for MFest 3.

The Karwerkz M3 retains all factory internals, and runs the same HPF stage 1 turbo system that everyone else runs. They ran the car on the race fuel setting with 112 octane fuel. Oscar removed the interior, added a custom roll cage, Enkreuz Wheels, K-Sport suspension and K-Sport brakes. They also ran DOT approved race tires and retained the factory oil cooler and factory radiator.

The other turbocharged M3's (Ray's stage 2, Brian's stage 2.5 and the HPF stage 4) were very fast at the track, and none of them had any overheating issues, in fact, the needles didn't even go past the half way mark on any of the HPF cars.

The Karwerkz M3 was the fastest of the bunch as it was designed strictly for road racing. It utilizes the factory high compression engine (instantaneous spool), HPF stage 1 turbo system, HPF subframe reinforcement, was lightened by removing much of the interior, and ran very sticky tires. However... this is their first outing, and after they upgrade the sway bars, add in the HPF speed based boost control and HPF traction control, and dial in the suspension, several in the industry feel they have a serious Time Attack car in their hands.

Great job guys, and it was a pleasure watching the car go around the track!!

Chris.

very nice! I should have lots of video of mine going around a road course next month. Our local car club has an event coming up on a nice, tight technical track in May.
not alot of straight to turn the beast loose but there are lots of on and off camber turns so it should be exciting.

Very Nice !

What was the outside air temp that day ?

[A55A55IN]

awesome vids! Can't imagine what a stage 2.5 will do on the track with the wide body :yikes:

[Mach_Effect]

Amazing! the corvettes and the porshe seemed like snails compared to the stage 1 m3.:thumbsup:

Nice video. Where are the video of the Stage4 HPF M3 on the track?

[babydevilj]

any more pics of that car?

wheres the white stage 3 HPF car?

wheres the white stage 3 HPF car?

If you are talking about Chris' car, it is now stage 4.

My car was running street tires and the turbo was a bit large for a short track like this. This track is ideal for a stage 1 through stage 2.5.

Interesting watching that video. Oscar's car seems much faster than your Stage 4. Probably the smaller turbo and R-Compound tires? When will Brian's video get uploaded?

Oscar's is faster
#1) high compression engine (virtually no turbo lag)
#2) smaller turbo (virtually no turbo lag)
#3) smaller FMIC (virtually no turbo lag)
#4) high impedance injectors (better atomization of fuel)
#5) race slicks (better handling)
#6) entire interior removed (much lighter)

This is why we've now created a "track version" turbo system called an HPF stage 1.5 which is a stage 1 + high compression built motor. :)

[cyruzz///E46]

so you are decreasing the compression ratio from 11.3:1 to?

what's the compression going to be on the 1.5 kit?

i'm just curious. :D

Our stage 1.5 will be 11.5:1. It will still be able to run pump gas, but will utilize a built motor for 24 hour road racing abuse.

Is a real race team really going to use one of your motors or cars in a 24hr race?
which one????

By the way I thought it was funny how you said
"#4) high impedance injectors (better atomization of fuel)"
as a reason oscars car was faster.
Even though your stage 3/4 uses an AEM peak and hold injector driver and eliminates any issues like that.
The reason that struck me is that a few days ago I was researching the injector driver for my project car.
I think it comes down to his car was set up for road racing, yours was set for drag racing, and thats about it.

Interesting. This opposes the trend of "bigger is always better." :rofl:

I am curious as to why you did not put on the Nitto NT-05 on your car instead of the Invos. If I remember, you were giving a set away. Not enough time to put it on your car?

[DaBean]

Nice vids, but ehmm.. you guys know this wasn't a RACE, right? :rofl:

The spray pattern and atomization in most high impedance injectors is better than low impedance injectors due to the simple reason that there's significantly higher fuel pressure on the backside of the injector.

If you watch the videos of the 3 cars, and you see how the engines responded through the turns you'll notice the stock engined stage 1 M3 had virtually zero lag. Most of the turbo'd race cars these days are running higher compression engines to get better response, and it also doesn't make a whole lot of sense to run a 700+rwhp car in a race where many cars that are winning have around 400-500rwhp. So I think the power delivery in Karwerkz M3 is pretty ideal.

So it makes a lot of sense to offer a high compression built motor for people or companies that are going to track these cars, and a lower compression engine for people that want more power on pump gas and larger overall powerband at the expense of some lag.

As far as the tires, my car was last on the list of everything to get done for MFest. Nitto doesn't offer a race slick, so we're probably going to run Nittos on the street and Hoosiers at the track.


Nice vids, but ehmm.. you guys know this wasn't a RACE, right?


This wasn't, but the smart businesses are certainly in a race to build the best product out there and track testing them. That means getting our products into the race circuit in the hands of both race teams and people that are going to track their cars at various events.
