Cool Otis. FYI, the e30 offers as much engine bay room as the e28.

20 psi on the first time out?? You're a brave man!

24psi yesterday but it doesn't feel like it's faster, I think the engine can't take anymore air in.

I never updated the cage install, but it's all done now.

Dual 044's in there new home.


Fuel cell and battery disconnect switch.


Switch through the tail light, thanks Boris..!


Both seats with 5 point harness.


SFI roll bar padding NHRA rated.






Came out pretty decent considering it was my first rollcage install.
Car stiffened up a lot and I feel a lot safer now.

Next on the list is a C4 auto tranny and custom intake.

I like where this is going.

Otis you have a PM

Otis: what OD are your primaries on the exhaust manifold?

Looking awesome dude. Personally I would make those wastegate tubes slightly longer to dump under the car....its gonna get really hot in that fenderwell, no need to set the undercoating on fire

Otis,

Its been great watching your journey. Having those calls 5 1/2 years ago when you got the turbo and now look at you.

Congrats brother

Looks great Otis! You going to make it to the vintage again next year?

Excellent. Thanks. That's the size I've been working with on my own setup. Interested to see what numbers your new manifold yields.

Well after quite a few attempts to tune with the HX55 I've decided to down size the turbo. The twinscroll manifold spools it fast for it's size but the torque ramps up so fast it's going to murder me as traction is non existent at any speed at full throttle.

So going to try the BW S300sx 91/79, it's equivalent to a GT4088/94.
It's not the latest and greatest but for $$ it will get the job done. I was concerned about the size but it's similar to the 6466 with the compressor housing being 1" wider.
The BW weighs in at 27.5lbs and the 6466 at 23.5lbs










The HX55 will be going in 351w fox body project.

So basically that hx55 went from no power to full power?
Sound like fun But better then the little hx40 no?

.

Thats what I saw with the HX55. Spun drag slicks in 3rd at 5000 RPM.

Went out tonight after over a year, with the new manifold & turbo setup to stretch it's legs on 18psi.
My buddy has 2012 CTSV with a tune, upper pulley, heat exchanger it's pretty fast and just wanted to see were he was at.

Here's a 3rd gear roll at 50mph to 140, I cant hear his horn so I wait for him to go on both runs.


Here's a 2nd gear roll at 40 to 150, I spun but my buddy stays in it knowing that I'll be chasing him down.

Glad to see it back on the road! What does the CTS-V run in the 1/4?

Any progress on the c4?

Not sure what it runs, maybe low 11's..?
He's running 15psi.

Slow progress but starting to gather parts, C4 slip yoke, diff flange, Spicer 1310 U-joints. Paul is finishing up the tranny this month.

Todd I hope I can make you eat those rofl's.

A few updated progress pics.









I spent three hours re-aligning the head flange as none of the bolt holes lined up.


Welded a plate on the bottom to add all the vacuum lines.
Just need to drill and tap for 1/8 npt.


This is my first time welding aluminum and man you burn through a lot of rods.

That should be worth substantial HP where you want it! Great job.

I have a feeling this is going to uncork some power alittle.

That is all sorts of bad ass. I can't wait to see the next dyno plot.

When will you be making those for b34 heads to sell?

If your not thinking of building some for resale, can you try to think of it?

I would also be interested in one!

This guy used a 666 mani just like that on a stock m20.
Looks like it has a cam or something. You know how high rpm power completely dies on these engines normally.

I wonder if the m30 is more restrictive then the m20 though.
