Fairly stated. But I would refer you to Corky Bell's Maximum Boost, Chapter 10, Page 126-127 in my copy, wherein he discusses the distorting effects of thermal expansion. See also a similar discussion in A.G. Bell's Forced Induction Performance Tuning, pg 261. Worth taking the time to read.

Defintiely a work of art. Tuned in for results.

Thanks everyone for the kind words.

To Ken H.
I've never had an issue with a single flange design. An individual flange per cylinder setup would be ideal but not something I care to do.

The holes on the flange are large in comparison to studs.
There's 1/16" of clearance all around the studs.

OK. I'm just reiterating what I was told to do.

How much better is the clearance in an E28 chassis?

There is a lot more room in the E28.

O.k wastegate dump tubes complete and went for a test drive.It was very short lived to say the least, afr's were on the lean side due to more air flow but I floored it in 3rd and blew something in the tranny instantly.

Would this be primarily due to the flow characteristics of a tube manifold vs. log or the new turbo/WG setup?

I would think it's from the larger turbo, going from a 59mm inducer to a 66mm the air flow at lower speeds should be greater.

O.k back in action, swapped out the tranny and all is good, roads were wet so no full throttle action. Need to do some tuning and dyno time to see if all my efforts were worth it.

I can't wait to see that thing at VIR next year (if you can find a tranny that will take the crazy torque!)

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: 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?

Wow your right 5 1/2 years, your HX40 was put to good use for sure.

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.

T_C_D · Post by **T_C_D** » Jan 22, 2013 7:05 AM

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

Post by **Nebraska_e28** » Jan 22, 2013 9:46 AM

Any progress on the c4?
