NEW HPF TRACK Pistons, CCW Wheels and ACT lightweight FLYWHEEL

[HPF Chris]

Here is a picture of the high compression pistons for our "TRACK" motors. We can build these motors to any particular spec people want. The TRACK pistons in the picture are .040" underbore and are going into the sleeved block in the HPF "Track" M3. We're also running the HPF Stage 3 clutch with the ACT lightweight flywheel. The track motor is getting stuffed with stiffer springs and has a 9,500rpm rev limiter. It will only be running C16 and will have a huge fat powerband. The block will be back from Darton shortly and we will get it on the dyno.

I finally settled on a wheel combo. Since this car has massive Brembo 6 piston fronts and 380mm rotors there are few 18" wheels that will clear. We needed very light wheels but very strong ones because of the high speeds and the rumble strips. So we choose CWW C10 monoblock wheels anodized black, 18x11 front and 18x13 rear. We're going to run 315x30x18 Michellin slicks on the front and 335x30x18 on the rear. Last year we ran the 295's up front and we needed a little more front tire. Now with 315s and the reduction of 300 lbs out of the car and the 50 lb reduction in reciprocating mass I'm excited to see how this car behaves. :)

looks like a CP X-forged piston

are those anodized ring lands or just shadows? pistons look the exact same due to the white background

They aren't CP. I could take some more pics that show the definition on the pistons. The pistons are deburred and ceramic coated on the tops and have side skirt coatings as well.

[RK-Tunes]

very nice flywheel and higher compression pistons!
flywheel looks like the ebay steel one for e36's but i bet quality control on those act's are perfect!

[diegom6]

Besides CR (which might vary upon engine modification/goals) what's the main difference between both pistons which differ the shape of the top crown? Flame speed/evacuation/etc?

Someone school me on this.

[wazzu70]

Flywheel looks nice whats the weight? Steel? Hopefully steel.

I would think the track pistons have thicker crowns which would be hard to see in the pictures.

[5mall5nail5]

They're clearly wiseco pistons

[FastrTHNu]

They look the same in pictures. Any specs?

I run those exact wheels on My race car. CCW's are awesome!

The one piston has higher compression and a shorter skirt height it seems.

[FastrTHNu]

Well, would ya look at that. (needed My glasses)

[daytona M3]

They're clearly wiseco pistonsYep they look almost the same as my Wiseco,s.
Why not calling it Wiseco pistons instead of "HPF" piston?

[5mall5nail5]

Eh, you know how that goes

[wazzu70]

Most likely because they are piston made to HPFs specs. There are only a few companies who manufacture pistons. Most shops just have them made and put their name on it....pretty much how every other company works.

Exactly. We have worked with them over the past 4 years and have made three design changes in our pistons. I'm not sure if they've incorporated the changes we requested into their "standard" piston or not. And yes they are Wisecos.

Chris.

Awesome. I've also seen them on very fast cars at the track. For the price I don't think you can beat them.

How could you tell they were wiseco?

[Colby Colbs]

I could tell by looking at their main page lol

[5mall5nail5]

I've seen enough Wiseco's to know

[milKt]

Wiseco enough to know.

It is very rare when a shop uses their CNC machine to truly create proprietary parts,
especially pistons.

[wazzu70]

Very true. The number of HPF pistons sold a year would not justify the tooling necessary to make them in house. Its a much better use of equipment to have a specialized company produce them.

Does HPF even have a machine shop? In the vids posted a while back it seemed like they used a local shop to do the engine machime work, which also makes sense.

If its the PDX shop I am thinking of, they build the really high end M20 race motors for PRO-3. We are talking around 12k for an M20 with stock rods and stock pistons, just very precisely measured and weighed to get the best balance and tolerances allowed within the rules.

[Clubsport]

oh man, just because you have CNC equipment does not mean you can manufacture your own pistons....unless you straight up copy someone elses cam/barrel.

[Brody @ Miller]

People can't even copy things right, you have to understand what goes into a piston to know how to copy it. LOL

Our pistons aren't made at the name brand house. We (Paul) buys the blanks right from the source and machines them to spec. That's why we can charge "off te shelf" prices for premium featured pistons.

Wait til you see what our m/s 5x turbo pistons will look like.

[Colby Colbs]

The compressor wheels I have had made are EDM'd as well

[HPF Chris]

Anodized ring lands or no?

Anodized ring lands are typically for motors that have ring lands failing. Wiseco builds these into some drag 4 cylinder engines that are making over 1400rwhp.

Many OEM Direct injection high compression turbo motors have anodized ring lands

Not only high compression turbo, but high compression NA as well

BMW S65/S85, N54/N55 for example

With the combustion pressures that the HPF cars see I thought maybe it was an option to prevent micro-welding and help ring seal

Anodized ring lands are done to prevent them from breaking like the breaking we often see in the OEM M3 pistons. In all of the motors we've built (75 currently in cars and roughly 90 total), we've never seen a wiseco ring land fail even on detonated and leaned out blown motors. As far as ring sealing, our cylinders have zero taper using a sunnen machine and a 32 bit diamond plateau brush for the finish so the rings seal after one dyno pull. :)

Chris.

[BoostedE21]

Chris, a little OT, but how do you guys break in the motors? Or do you recommend the customer a certain method or procedure?

[Nate P]

Thanks for sharing Chris. I wonder what makes the S54 seal so much better then the previous generation.

A what? I use a lot of Sunnen products. Never heard of a "32 bit diamond plateau brush". Is that Windows 7 compatible??:)


Don

[jmargo]

Maybe 320 grit diamond plateau brush ?

[BadBoostedBmwM3]

What is the stg. 3 HPF clutch. Is it still a SBC feramic disk? BTW, why did you switch do the ACT flywheel? I thought you all advocate the OE flywheel...

[HPF Chris]

The OE flywheels work better for heat dissipation and drag race launches. Since this is a dedicated track car and doesn't see any launches I'm excited to lose the 20 lbs of weight.

I misspoke. The Sunnen machine that Brian uses runs 4 abrasives and each abrasive has 4 cutting edges. The abrasives have diamonds in them and this is used for the honing process. This creates a very round hole. The plateau brush is done afterwards to clean up the cylinders and turn them into a mirror like finish. :)

if im not mistaking you guys use single disc clutch for 1000hp? right ?

I dont think one likes mirror like finish on the cylinder.It looks cool,but will burn the rings in a few laps:shifty

[HPF Chris]

Actually, that's the old way of thinking. Those peaks on the cylinder walls just take time for the rings to wear them down. Our motors don't smoke ever. They come up to complete compression on one dyno pull. It's amazing.

Chris.

Do you have anything like that for e36 m3 ?

[dcvee]

All automotive machine shops (that are worth going to) have that capability. Doesn't matter if it's for a 5hp briggs racing motor or an e36 M3. It's pretty much standard procedure for a high performace bore using current piston/ring technology. Ring manufacturers have their specifications for bore finish....it's the job of the operator to apply that finish.

Sry I forgot to quote chrisis word to me . My question was if they can make 1000hp single dick clutch for e36 . I apologize for miss quoting him to some reason I'm not getting full exposure on my IPhone :( . But yes I am aware of the pistons being coated and machined for high hp cars , mine are getting the same treatment :)

[SiGmA]

Anodized ring lands or no?No, its just a bad photo.
They're clearly wiseco pistons+1.
How could you tell they were wiseco?Cuz they are using Wiseco's 2008+ design. Look at almost any Wiseco made since roughly late 2008, they all have the same skit design and coatings. The only thing special that I see is a shorter skirt, higher compression, and slight extended valve reliefs. The skirt could be visually and not actually shorter perhaps. Tho its common for 'track' pistons (high abuse/RPM) to have shorter skirts.

I hope you dont say that someone is actually doing MIRROR like finish on the cylinder.That means no hone at all to me.

Most machines shops don't have the latest Sunnen equipment and rarely remove taper from cylinders. I think there were only 3 of these in the Northwest at the time we made the videos above. Watch the videos. There's a lot of tech stuff in there.

Chris.

We had both front strut towers move and break the seams at the GTGP 2010. Not anymore. At the same time we are removing a ton of weight, we are also reinforcing those front strut towers. The top of the strut tower will also have one of strut tower plates welded to it and we are also building a custom strut tower bar to connect the two. The bars in the picture are only tack welded in at this point.

Chris,thank you for the clips,I actually took my time to watch and enjoy them.I have just a few remarks:
The machinist guy is using mirror finish for the head mating surface,which I agree.Actually he said that the diamond cutter doesnt work good for cast iron.
As I mentioned,if you use mirror finish for the cylinder you wont have any lubrication for the piston rings and they will overheat in a short period of time.
The overall context was that the S54 was not properly assembled (designed?) in the factory,not using torque plate , etc.

I'm sure there must have been a reason for non torque plating the motors. They distort quite a bit with the torque we put on the head bolts so they must be torque plated.

[Colby Colbs]

No base plates welded to the tube and strut tower. Why is that? Ideally you want more surface area at the base...

True. In the post above I said, "The top of the strut tower will also have one of strut tower plates welded to it and we are also building a custom strut tower bar to connect the two" It will all be done on Monday and I'll post up the final pics. :)

Gotcha, I was talking about the plate that goes to the tower where the tube intersects. Hope you don't mind, just posting a pic from my build thread to clarify.http://i201.photobucket.com/albums/aa275/ride4life46/BMWPOWER014-4.jpg
