HPF Stage 4 M3 Videos and Pictures

HPF Stage 4 Information

We're wrapping up our stage 4 turbo M3 development. Now we're on to the tuning phase. We just finished doing the subframe reinforcement on our HPF M3, and upgraded it to the stage 3/4 fuel system. We also added the HPF traction control and speed based boost control to it. It is now running the Asuka widebody (4 inches wider on each side) and rolling on Hoosier R6's with 345's in the rear and 295's in the front. We also swapped out our stage 2 clutch for an even stronger HPF Stage 3 clutch to handle the added 100rwhp.

It's running extremely wide Enkreuz wheels (19x10 in the front and 19x13 in the rear), Massive brembo 6 piston brakes and KW Suspension Variant 3 coil-overs.

This car is going to be brutally fast with the increased traction and the traction control system and will be able to apply that power to the ground very quickly. Our Veyron killer is nearing completion. :) I have a friend that is hopefully buying a new Veyron, so we will get some good races on video between the two cars.

We will have dyno results very shortly (we're going to target 900rwhp - 1100bhp)


Here's a video of a walkaround on the car.

Here's a video of it driving over to the dyno.

ridiculous!!!!!! yay first reply

[HPFMTRE]

i cant look at these stage 3 and now stage 4 videos anymore lol im going crazy.

[JJR4884]

i cant look at these stage 3 and now stage 4 videos anymore lol im going crazy.

pfft your car is slow now..... :P

[mdsonicTT]

have you considered cf/cleared side moldings or LEDs? think it would make a nice contrast and flow with the current CF scheme nicely.. really compliments the curved bootlid well (upgraded lights).

can't wait to see the in-car video hearing the car at WOT! :yikes:

[///M3-QTR]

Yea we want some action vids !!

Stop teasing us Chris !!!!!

[HPFMTRE]

pfft your car is slow now..... :P

:bawling: :(

Bro, if you're not happy with your car's performance as is, then you have a serious problem!!! :D

[HPFMTRE]

LOL hahah trust me i LOVE the way my car is now...it would just be nice to have 900rwhp at tap lol.:rofl:

[jtrejo]

sweeettttt

[m5er]

Badass!!:str8pimpi

Bro, if you're not happy with your car's performance as is, then you have a serious problem!!! :D

lol, +1. I can't imagine Stage 4. :yikes:

[Evil Twin Rob]

Ahhhh, the Veyron. Most super of the super cars IMO. To hang with a 1.4 million dollar car is a true accomplishment.

[leletyM3]

Can't wait to see some more vidz!

[Ferm3]

Ssssiiiiiiiiiiiiiiiccccccccccccckkkkkkkkkkkkkk!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[S52BMW]

Awesome. Subscribed.

My friend is supposedly paying 3.2 million for his. Maybe the price has gone up a bit.

I just read somewhere that they have special edition ones that are more expensive. Must be what he's getting.

It could also be that is when they were being sold production. Now that they are in people's hands they have that inherited value that comes with owning cars that nobody else has because they are already owned. Then consider who owns them.

Still ridiculous.

You guys need to get this M3 to the Nuremberg Ring. Might be a bit of a hctiB in the twisties but in the straights omg....


Last thing. Could I get a set up where I have 2 gas tanks..one for regular high octane and a Race fuel cell for the 110 gas...so that means...2 seperate fuel pumps controlled via a switch?

Just a thought...

~Ron

[kcalhoun27]

awesome job, but im not feeling that gas cap. but still, you guys rock at what you do, thats a fact

[BartenderPlease]

wow this is gonna be siiiick :drool:

[asianjedi]

Awesome power.

The widebody conversion looks like quality work...but not a fan.

[02PRUV]

Will be interesting to see how the subframe reinforcement goes. You are doing the same as what I did when me rear end first started cracking. All it did reinforcing like that was rip out the whole centre section of the boot floor all in one piece. And I did that with less than 500rwhp and standard street tyres.

Good Luck:thumbsup:

[richvizz]

Having run Hoosiers for years on track, do you really think that is gonna be your best choice for street driving? They really arent too sticky until they come up to temp, getting them up to temp on the street may not be an easy task. I imagine you will have to play with pressures big time. interested in hearing how your tire choice works out...

[ice330ci05]

WOW.... car looks good, i guess i got used to the Widebody! can't wait to see the end result! hope this is the last stage and you get started on the 330 :D


by the way, what ever happend to the CD you were going to send out?

[Ferm3]

Same here..not a big deal...just wanted to watch it :)

x3. Never got the CD either.

[S52BMW]

Any updates?

[///M3Turk]

:excited:

[HPF Chris]

I decided not to send out any more DVD's until we make a new one, and we've been very very busy.

As far as our stage 4. We started tuning on it yesterday.

This will be a slightly different tune than what people may expect. We are only able to target 2 boost levels. This results in the following results ( I noted the difference in red)

Stage 3
Pump = 15psi = 600rwhp
Pump + Meth = 23psi = 760rwhp
Race = 23psi = 775rwhp
Race + Meth = 23psi = 800rwhp

Stage 4
Pump = 15psi = 600rwhp
Pump + Meth = 15psi = 640rwhp
Race = 28psi = 875rwhp
Race + meth = 28psi = 900rwhp

The reason we can't make more on pump + meth with stage 4 is because we would have to run it at 28psi for our setup and there's no way to prevent pre-ignition at that boost level when pump is used.

We made 640rwhp yesterday on pump+meth at 15psi. Which is amazing for a low compression 3.2L engine at such low boost. We currently have a vibration issue with the new wheel spacers we're running and need to address that before we run high boost.

I'll keep you posted.

Working hard on sundays... Great work HPF, can't wait for the results!! :thumbsup:

[Greg Ogden]

Looks good! Can't wait to see the final results!:excited:

RTAB's RTAB's RTAB's. The way this car launches on the dyno is literally pulling the tire all the way to the front of the wheel well, then back to the rear and hitting on both the front and the rear. We did a test and ran Volk wheels with 285 drag radials and the wheel hop was gone however several people had to sit in the trunk to keep the tires from spinning.

We're going to install some RTAB's on this car to see if this eliminates the wheel hop with the sticky Hoosiers. I always abided by the phrase, "if it ain't broke don't fix it". Now I can say that RTAB's are clearly necessary in high power cars with good traction.

We made 820rwhp on race fuel when we started having the wheel hop on the dyno. The stage 3 clutch is holding but the pedal effort is significant. So we're also going to test out OS Giken's new triple disk clutch. I'll post up pictures of that shortly.

I'll keep you posted.
Chris.

[S52BMW]

Saw you on bimmerforums ;)

[mtran850]

Chris, Where did you get those 285 drag radial? David is checking on those HRE wheel that can fit 305 on 19 without body works, do you have any pix and what is the rim size. I would need it asap along with the TC System quick because rumor have spread and fans and haters along the Gulf Coast are wanting race the one and only Gulf Coast HPF Stage 3 M3. I got to preserve HPF M3 King of the Road signiture along the Gulf Coast. :str8pimpi

I inquired about this exact kind of setup. Although nothing is impossible, I was quickly steered away from this idea. I guess a BMW fuel system is a bit more complicated than an old Ford pickup. Of course, after I went to stg 2, I found that 580 rwhp was plenty for daily driving. The only time I run race fuel now is when I go to the drags, or I set up a serious street race.

We definitely need to get you some good rubber and wheels. The shorter the wheel the better. I would run 17x10's and some drag radials in the rear. Definitely work with David on those. :)

I've got some great news.

The OS Giken triple disk clutch has a very smooth engagement and the pedal effort is just slightly stiffer than stock. It is nothing like the triple disk clutches I've used in the past. It's just awesome. Pretty soon we'll put it to the test for Horsepower.

I'll do a complete writeup on the clutch shortly. We also have another one coming in 1-2 weeks if anyone wants it.

Chris.

[deafboy]

I might have to drive down there one of these days and finally get a look at your guys place.

that is just mind blowing :yikes:

:bow:

Thanks for the input.

Very, very impressive Chris. HPF has, and continues to, create some extraordinary possibilities for the E46 M3. I love it.

hey i love these hpf turbos you guys should post up your amazing cars on http://bmwpsi.com
