Prototype BW turbo... titanium wheels?

[Full-Race Geoff]

i am not able to disclose any information about the wheel materials or bearing assy but i will share as soon as they give me the green light -- very innovative stuff

[bigmikespec]

Out of interest did you ever end up switching to the S300SX 83/75 before changing again now? Seems like a good option for a stock stroke RB26 but there is so little info on these turbos on RB's.

i have the 83-72 but in bullseye power. no figures to report as the car is still in bits.

i see that they have tried reducing the inlet to 100mm 4" instead of the pain in the ass 5.5" inlet...

Ahh, what do Bullseye do to BW turbos to make them "special"? 5.5"inlet what a beast!

i strongly recommend that you use 100% genuine borgwarner airwerks turbochargers!!! Bullseye power is a knockoff of the BorgWarner, it is not the same.

here is the latest update for you guys:

To start this installment, many hardcore car guy know that the best suspension in the world is MOTON. Seriously - nothing else comes close. I researched my options - considered ohlins, bilstein, kw, penske but at the end of the day, none had what i was looking for except Moton. I HATE upgrading parts and only want to buy good suspension once, so i bit the bullet and what showed up was heavenly. The quality of these absolutely exceeded expectation, and im blown away (im a very picky engineer, this doesnt happen often) suspension of this caliber is seriously next level :bowdown :bowdown :bowdown :bowdown :bowdown :bowdown :bowdown :bowdown :bowdown :bowdown :bowdown :bowdown :bowdown :bowdown MOTON

^^ a total thing of beauty. Moton double adjustables (15 independant bump and rebound settings, blowoff valve system for high speed bump control, huge main piston, remote reservoir compression adjusters mounted on swivel banjo fittings (makes mounting them easy!), and 2.25" spring hardware.

^^this is the top-secret R14 front suspension ive never shown anyone before. consider yourselves lucky :rotflmao the Motons fit so perfect, its like the motons were just meant to be..

this is showing the drivers side remote reservoir compression adjuster

(pass side)

now to the rear --

installed (but waiting on the tender springs to arrive)

reservoir located, you can also see the fuel pump wiring

easy to see how the adjusters are mounted facing inwards, easy to access without removing the wheel

tire clearance at full droop

tire clearance at full bump

both reservoirs mounted, and the wing mount i am building now from 0.035 4130 cromoly

NEW prototype BorgWarner Twinscroll Turbo - dubbed S300'P'

^^^look at the super badass turbine wheel geometry and my favorite feature of all, the vband compressor hsg to CHRA. soooo slick. I am looking to spool 1000rpm quicker and make 700+whp at 30psi boost... this should do it.

the legendary extended tip compressor wheel design, this is only 61mm inducer / 83mm exducer turbo, just like a GT35R but it moves 72lb/min at full-tilt, HUGE airflow for this small of a turbo (35R is 62lb/min for example). take a look at the far tip you can see the little "peak" that is mountain shaped on the top of each blade? thats the extended tip

getting ready for the charge pipe modification

4" downpipe flange welded on

^^old vs new... you can see how much smaller the new turbo really is

^^got the manifold and downpipe 2000degree HPC coated, and will use DEI heat wrap on top of the coating to further reduce engine bay temps

Front Aero

^^front splitter mounted on the car, you can also see the radiator ducting. coolers will be remounted and ducted next

^^strong enough for 330lbs @ 0mph, should handle 300+lbs downforce at 170mph!

Rear diffuser

to make a functional rear diffuser, it requires that there be an area with no obtrustions to block air from exiting under the chassis or from behind the tires. I started by cutting the quarter panels level with the frame rail, and then i cut out the spare tire well

^^cutting quarter panels level with the frame rail

^^removing spare tire well

^^20 ga steel plate fabricated, and mig tack'd in place.

^^welds cleaned up, spray painted grey

flat bottom rear is finished! now time to bolt up the diffuser when it gets back from powdercoat on monday :naughty

this bumper will be trimmed generously!

another shot of the rear, but this time the new spindles with proper toe rod geometry is installed

as she sits tonite, getting ready for a looong weekend!

now i have to corner weight the car, align it, and do a few tweaks from my friends from M-workz and motoIQ, then i can finish the aero, and turbo for one last update before the race. see you guys for one last update in 1 week!

This is my favourite build up ever! Thank you for sharing, you have carried out some very skillful work and provided alot of insight.

Keep up the good work! Hope it all comes together in time for you.

[Beer Baron]

LOVE IT!

now it's getting very serious mate. no real criticism I can think of. should be very fast. thanks for sharing.

[Marlin]

Thanks for taking the time to share this with us mate, it's awesome!

I especially like how you just don't fark around, you just chop it. I'd sit around procrastinating about it

[phunky_monkey]

Looks awesome Geoff, can't wait to see the finished result.

[sav man]

wow that's some pretty epic dynamic camber. Have you measured bump steer, and dynamic camber after all your changed?

my friend has a skateboard that on the bottom says "Scared Money Don't Make NONE" it became a joke around here but its the truth, if youre sitting around bullsh!tting you wont get anything done -- so cut the bitch!! we got work to do, no time to sit! haha

bumpsteer is perfect -- 8.50" inch traction rod, 12.25" RUCA - i suggest anyone with an R33/R34 or a modified R32 rear subframe run this link length

great test of the front splitter that pic is a crack up.

I think I have spotted an issue at the rear......you have no fuel tank....at least you have space for the diffuser.

we have been struggling with the same issue, fuel tank, 2nd radiator for the water to air intercooler and a diffuser all meant to go in the same spot

[Full-Race Geoff]

only s13/r32 have the fuel tank there. s14/r33/r34 have the fuel tank above and in front of the rear subframe (under the back seat)
