Fast Intentions Stage 2 TT build by MA-Motorsports.

Bman427 · 12-30-2019, 10:18 AM

I'm building it to drive like you have done with your car. I wont lean on it real hard very often, probably stay around 12-15psi if I even get that far...

Remember there was a build on here from a polish Guy? He wrapped his 370 red and posted some street racing vids, running 800whp on 93. He did studs instead of sleeves.

My friend runs 22 psi and 830hp, for about a year now. He burned a valve, but that's it..so far..

Anyways, goodluck!

Just read the updates here, really sorry you went through this Spooler! I know it comes with the territory, but it still sucks big time. Thanks for continuing to share your experiences, both good and bad.

Diabel actually used rods to stabilize the cyinders. It was genius as hell. I actually copied his build with mine. How to get those rods done bothered me so much I just gave up on and went with his base build. He finished up with 771 on 100 octane. My goal was to meet his power which I'm pretty sure I've done now. Difference is he used Jun cams and I used JWTs and also he was 9:1 and I'm 10:1. That'll change sometime soon since I'm probably going to switch from the PTE 6870 to the new Comp air cooled 6871.

This problem is so FRUSTRATING. Still researching. Very little data to be had.

A 3 or 4 Axis CNC is needed for the machine work to keep the tight tolerances.
As long as it has been machined properly you shouldn't have any longevity issues.
CAT, Cummins, etc. have been using this for years in diesel applications.

Are you talking about pinning the sleeves? You can get that done at pretty much any machine shop. Its a simple process, just not a DIY type thing if you dont have a the machining equipment. I have never personally had it done, but Id imagine somewhere in the 600-750$ range based on other custom machine work ive had done. It seems a bit inconsiderate of coolant flow though.

I had Darton wet sleeves installed to a block for my car a few years ago. It was done at a machine shop that makes some of the billet VR38 blocks, they were very well equipped for it. Unfortunately I was too busy to build my car and ended up selling that block to someone on here, never had a chance to try it out. Im not sure of anyone trying them in a built VHR yet? The guy who purchased mine, his car sat a couple years but they did just finally assemble his engine, so we will see how his turns out soon.

That was part of my issue with it Charles. I have to be able to conceptualize something to have confidence in it. At the time I was going back and forth with this and a closed deck or just open. After I considered not wanting to go higher than 800, I abandoned the idea. Then I choked myself again after the build when Seb started mentioning concern of headlift and making me pinky swear I had L19 hardware when I started asking for 20psi.
I'm actually shocked Spooler got it at 17psi because I spiked 27.8psi and not an issue. I roll around at 18 all the time and have been playing with my 21psi map 4 lately.

How many miles do you have on your build? I had 7000 miles on mine. You may be OK or you may not. Just don't be surprised.

I have talked with Brian today. We have decided on a solution and what we need to do going forward. He has talked with the machine shop that built my engine today also. We are still gathering information to ensure we are on the right path. Everyone is backed up. It may be a little bit before my car goes back to MA. Brain is working on the scheduling nightmare. We are going to do several things. MA-Motorsports is taking care of me. That is a good thing. It would be unreasonable to expect it all for free. I am not expecting such.
