RIPs fabrication is second to none, the quality and craftsmanship is absolutely astounding, I know because I have quite a few bits custom made from Rob along with the RB30 he built for me. I can safely say that no tuner in the U.K can make these bespoke parts and be competitive with RIPs pricing. That's why my custom went to N.Z. Rob I am seriously thinking about the GT42....

Speaking of big turbo's, here's a manifold we are making for the 240z to mount a new GT45 1200hp turbo, there's alot of time in each tube to ensure perfect flow and merge of all the runners:

Not sure what happened to that last pic, but here it is again.
[IMG] [/IMG]We thought we might run the exhaust like that to give jet propulsion as well as we tended to head to the left part way down the strip, also with that last guy getting killed by a turbine wheel I think there'l be new rules that you have to exit upwards or to the rear downwards not straight out horizontal like before.

Yeah that was a bit grizzly, you don't normally think about how much heat the turbine wheel would be holding until something like that happens. I dunno about that exit though - would be a bit worried about trailing you in your left hand lane on the off chance anything managed to escape out there. Should help with the down force, I can't imagine how light it would get in the front heading down that hill!

Yeah the exhaust should help keep the nose down on our downhill tracks, lol.
Exhaust angle does help the big boys (Not saying we are even remotely in that leauge) but I've seen fuelers head towards the same side of the track as cylinders that have failed.

Amazing fabrication skills
, how do you even mark the exhaust to cut it to those shapes. Do you use paper cut outs to do the marking.What happened with the guy who got hit with the turbine wheel, I have not heard that one before. Last edited by David; 10th September 2008 at 01:01 PM. |

Rob, how on earth do you calculate the profile at the ends of the pipes where they merge? Its mind boggling to look at let alone actually work it out!

Its all just time and lots of it.
When you compare the collector on one of our manifolds to a mass produced HKS or similar, there is no comparison, I was actually quite shocked when I took a look at a HKS manifold for a T51 spl, even the wastegate integration was very poor IMO. Anyway, its lots of time, lots of love and no comprimise that gets the end results. Rob
