Yupp.

Front (this is just a template) is taking shape:

I want one.

Why not one IC?
Who supplied the half shafts?
Did you say adjustable boost?
Great Body work.
Go IF2 team.

We couldn't find big enough. With two we clear the fan too.

A Swedish shop called "Sellholms"

Yupp. Motor was dynoed @ 2 bar and CSP racing fuel with the wildest map. It produced helluva lot of ponny's. (Enough to make Juan envious)

And that was before headers, intake and intercooler were upgraded. 1000Nm of torque too.

Thanx!

Few updates. Things do take more time than planned. It's getting tight and we have two days of shakedown planned on 20:th of april.

First shifter iteration:

Front is being tidied down before making a template:

Should look something like this:

Two coolers to be installed on each side. One for gearbox oil and second for turbocharger cooling loop (this time it was decided to actually use turbo coolant passages):

It's now time to do dirty time-consuming work of making all those grandious ideas actually function in the way it's intended.

Plenum is being assembled in place (some sheet metal had to be widened):

I actually believe this will make difference:

It's not just race, it's show too. We must have stereo and stuff in the doors to please the sponsors (don't worry, we'll remove it before Nurburgring

):

This is going to be main engine harness when it grows up...one day

Carbon-fibre sheet is being cut. It's a good omen.

Hey Goran,

As others have said, what a nutty and great project! I have a friend who has done some similar things. Check out http://www.ultimav12.ca/ for some of his madness. There's a lot that's not shown their including a McLaren M6B 'replica' (built using original NOS M6B tub), a 550 replica with a Hyabusa drivetrain, a single seat V12 monster using a CART Reynard tub etc...

Quick question on the boost and intake. When you said 2 bar of boost, are you talking about 30 psi of intake pressure? If so, has someone done a quick check on the wall thickness to make sure it's strong enough?

Good luck meeting the deadline. That's always the toughest part with projects like this.

Hehe, that was a great homepage (the one with V12 Ultima). We know a guy building Ultima with, now get this: Big Block Chevy with alloy heads and...jeezz...twin turbochargers!! He bought our old zero-mile 930 gearbox. It's going to be a handfull!
Pic of his engine bay:

Yes, we are talking 30psi of boost. We never did calculations but we use same sheet metal thickness as old one so it should work. We'll do shakedown tests so if it plenum cracks we'll re-weld it and reinforce it. It's just important it doesn't crack on Nurburgring. But chances for that are small as we'll drive on ring on "endurance map" and no more than 16-17psi of boost, to spare the engine. It should be good enough to catch a CGT anyway

.

More pics from today:

Tokan is free-hand designing front spoiler:

Should look like this:

Mr Beau · 02-25-2006, 12:21 PM

Jay's 400 HP Ultima should be 'quick enough' for most people. Consider that it weighs the same as a Miata to give you an idea of power to weight. Not sure I'd want to drive one with a TT BBC. :-)

I hope the TT BBC did some chassis modifications as the factory cage structure is just not very stiff. Another mod Jay did was lower the engine around 4" or 100 mm thanks to a drysump system and some hacking of the transaxle bellhousing.

beepbeep · 02-27-2006, 07:56 AM

Front is nearing completion:

"Classic" RSR reinforcement is being done. I got ideas for in-situ reinforcement from RSR threads/pictures on this site. We also opted to weld one of cage pipes directly into shock tower, which will hopefully make car more rigid. Right now, chassis is something between full spaceframe and usual self-supporting sheet metal frame.

Goran,
Looking good!! I always am eager to read your latest updates. Makes my project look like child's play.

Is the spoiler on which Tokan is working going to be a plug, so you can make mold from it and then a lighter one? Or is it the production, but also prototype version?

Front spoiler on picture is just a plug. It's going to be polished, then oiled. Then, a mold is being made in fibreglass which will serve as a original for making carbon-fibre front/spoiler.

From there on, there won't be any front lid, whole front/front spoiler/lights will be removed in one piece by pulling two levers and sliding it off.

Face/off:

Skin grafts:

The plug:

Test-mount of plug (this is just a plug, it's just a template of the real thing):

beepbeep · 03-04-2006, 06:43 AM

New plenum is finished (red one is old one, it's for sale together with old intercoolers if someone is interested):

Instead of mounting thick spacers to move wheels out (so they can fill the fenders), it was decided to move suspension pickup-points instead. Otherwise it would be very hard to avoid go-cart steering feel (in the bad way):

I love the grinder picture because you know hes gonna stop, pick up the coke sitting next to him even though some metal shavings got into it, and take a nice long drink. Fuchin hardcore Swedes.

Keep em coming Goran!

There was no AC/DC TIG welder around so turbo plumbing was made with what was available at the shop: stainless steel plumbing:

Front suspension pickups taking place:

THE engine:

DW SD · 03-04-2006, 07:23 AM

What front struts are you using? Looks like a gusstted Bilstein lower with a coil over fixture attached? OR Is it the early RSR style?

Are you changing the lower A-arms, too? OR going with a 935 style?

GREAT JOB and GREAT update!

captainrb · 03-04-2006, 07:30 AM

Just my .02 .. first off super,great job !!! Although I'm wondering why it is when you made a custom upper shock mount it didn't have any adjustability for changing camber
