ILSA and the Vertical M50/M52 Turbo

Small lesson, but valuable gains!

Haha, I try to make it 1 step backwards, 2 steps forwards =D



Ok heres an up date for ya's


Got the head back from machine shop... the spec is:

Cutring Gasket
New Guides
New Seals
Ferrea Competition Exhaust valves
Oem Intake valves
Decked
M50tu Springs
M54b30 Trays and lifters
M54b30 Intake Cam
M50b25NV Intake cam as exhaust

Big thanks to Someguy2800 for the cam and these nifty NV timing blocks, makes timing a breeze and he makes all sorts of custom timing blocks hit him up!



Cut rings are badass, should have done it the first time!




Also designed and made this billet thermo housing. I plan on doing a rear mount rad eventually



Torqued!




Should be up and running sometime later this week. Going to take it EASY, and get my tune in order before leaning on it too hard. Will let ya know how it goes

[Substance D]

OK massive update!

Titanium Hardware for manifold




All reassembled!



Did a couple days of tuning, easing into it this time around. The fuel map is sorted, still playing with timing, but it looks like she's holding together! =D

Also have been doing alot of testing of the Billet Thermo. I have a 88c thermostat, and only a pusher fan, and the car runs 190-197 sitting in traffic, I am very pleased.




She's pretty much ready for an event... Im going to setup flex-fuel, throw more boost and timing at her and go have some FUN!!

THis is pretty bad ass, glad to see this! Wish the motor came in at 20 degrees from factory, would save so much trouble. Where do those lines on the housing you made route to?

This looks so right

Any reason for that cam setup besides cost? I commited the sin of snapping an s52 intake cam so im runing s52 exhaust (same as NV intake) and m54b30 intake on an s52 bottom end.

Haha thanks man! I wish they came like this too, but its been well worth the effort. Those lines go to the radiator, I plan on doing a rear mount radiator eventually, but wanted to test the housing with a standard mount, the outlets on the same side, because I converted a stock style to Dual-pass. Not really worth the effort, but I like testing stuff =)

Thanks alot dude, I AGREE!

I did these cams because they are a fraction of the price of M3 cams, I was coming off stock M50tu 228*, and for my purposes they'll work just fine. Shift the band a little to the right to take advantage of higher rev limit, but still keep it wide =)

[Substance D]

Well some sweet, some sour, such is life...

Got her all back together after blowing the HG...Things were looking up. finished the billet thermostat housing AN conversion with this custom radiator.




Heres a 3rd-4th gear pull



Some Rainy day fun




But...I have been chasing smoke...I HATE oil smoke...I have oil smoke puffs on revs since I built my motor. I have tried open atmosphere CCV, running a Secondary Air pump as a Vaccum pump, Exhaust venturi CCV, and even hooking up the CCV to the intake manifold with check valves like a normal PCV....Nothing has helped, I have brand new valves seals and even guides...still, smoke on free rev. I have run as much as 10in/vc and that helped a little bit, but it was not possible to maintain that level of vaccum under boost without dry sump $$$.... I plan on tearing apart my bottom end, and drilling the Valve covers for 2 -10 ports and just trying to keep CC-pressure at 0.



I'll leave you with a video of me thrashing my brothers truck, 1973 C10 454 that we just got done Megasquirt-ing.

[marc79euro635]

Why are you using a pcv valve? You do have the vent run to the turbo intake side right? That should suck even better at boost. I'm having a bit of smoke on my turbo as well, but in my case it's the oil drain hose leaking on the turbine housing.
good luck!

I was trying to fix This blow by with a PVC haha

Melted Head


Smoked Pistons



Cracked Block




DO OVER

[et89]

Damage and do-over in one post! don't see that too often!

any idea on what caused the damage?

Well, that motor was cursed from the beginning. I sent the block to be machined when the pistons arrived, without measuring them, and it turned out Wiseco sent me mis-machined pistons, wrong diameter, and wrong compression height. But the block had already been machined, so I got replacements, and the tolerance of errors was probably too high. The motor smoked from the initial fire up, you can actually see it in an old video. But I soldiered on, trying to tune it up nice, however, it was too much sauce for 91 octane and 9.4 compression ratio. The goal was to get it on e85, but I like breaking in on pump gas. Too much right foot, and too much timing per octane on a messed up motor = much detonation.

Fired up the new motor, NO SMOKE! =D

[Mklock]

Holy mooolay lol. Nice job!!! Looking good. Pump gas can get imteresting for sure.

[5mall5nail5]

Hey man - great thread, dunno how I missed it.

One thing I noticed in your earlier screenshots from datalog is the boost creep - it doesn't seem to build and plateau but rather it continues to slowly climb, just like the rest of us have with "ordinary" wastegate placement/issues.

Were you able to remedy that?

Haha thanks a lot man! Yeah, I haven't had a lot of luck with pump 91, only low compression 8.0 and low boost, never liked meth injection because I do so much on throttle, off throttle drifting, I feel like it cant keep up and dead pump means dead motor, but I've killed enough on my own hahaha

Hey thanks alot, its cool seeing the OG's in my thread =). The boost creep in that log caused by my forgetting to plump the IAC, so I had about a 1/2 inch hole in my intercooler piping. On this new motor, in the very limited testing I've done so far, she's spooling earlier, and holding 14psi solid to redline.

I've put 500 miles on the motor, running well, but the starter died. Gotta fix that, Gonna do oil changed, and switch over to E-juice and then really let her sing!
