Hi Alan
Thanks
Good to see you're motivated.
I'm going to make an air box over the throttle bodies, fed via a tube from the front of the car with a big air filter at the end of it.

Yep - a fist full of dollars .. and really keen to see it finished.Thanks

Not sure if I want an air box .. do I have space ? not a lot .. or do I want a hole in the bonnet (not really) ..
Might be a throw of the dice to decide or just let the brain decide. Cold air wins right ?
Might have to decide soon .. cannot run without a bonnet for ever.

Wildpussy first let me tilt my hat in your direction for taking on this project, i personally can't wait to see this wide-bodied beast 
Secondly your sorely misguided if you think this is going to level the playing field on the road to Spa
Hurry up and get it finished!
I've already told him that I'll give him a few lessons first Secondly your sorely misguided if you think this is going to level the playing field on the road to Spa

I hope to be @ Brands and hope for better luck than last year lol very expensive weekend in DTEC although CSCC was fantastic bar the safety car taking me from front to back!
Hope to see you out soon
Here's the latest
My Tremec TR3550 gearbox came with 0.68 fifth gear which is good for Motorway cruising but not suitable for track day work. After hunting around for a different 5th gear ratio, I spoke to Paul at Libertys Gears in the USA. Somewhere in his workshop, he had the rare no longer available 28-spline mainshaft with 0.82 fifth gear set that was a High performance road race option for my gearbox.
The other companies I contacted offered an alternative method of changing fifth gear which involved internal machining of the tail end of my gearbox casing to fit the later 31-spline mainshaft with a 0.85 ratio from the current Tremec TKO gearboxes.
After more time spent researching the web and further discussion with Paul at Libertys Gears, I purchased the following parts - Carbon fibre lined blocking rings for 2nd, 3rd, 4th and 5th gear, bronze shifter fork pads, modified 1st & 2nd shifter rail with a stronger spring, neutral switch & Speedo blanking blanks, Pro 5.0 mid shift kit and the rare 28-spline Mainshaft with 0.82 fifth gear set.
These arrived mid January
Paul Nash - Race car engineer / Consultant - stripped the gearbox and fitted the parts.
He reported on inspection that the gearbox is 'as new' inside with no evidence that it has ever been run. For some reason, it has a used input shaft fitted. He concluded this was done to change the input splines from the originals the gearbox came with for its then intended installation.
Happy Days

Hi Alan
Could you not fit a T5 or Getrag. The Getrag 5 speed gearboxes out of Jaguars and BMW's were used as an upgrade to the LT77 gearbox years ago. John Eales used to sale bellhousing to mate them to the Rover V8 engine. He might still sell them.
wildcat600
Yes - I think both would be an option worth looking at.Could you not fit a T5 or Getrag. The Getrag 5 speed gearboxes out of Jaguars and BMW's were used as an upgrade to the LT77 gearbox years ago. John Eales used to sale bellhousing to mate them to the Rover V8 engine. He might still sell them.

The old LT77 should be OK for a while.. when it lets go I will change it for something stronger but first priority is to get the car finished.

quite a few of those getrags found themselves behind V8's in early cobra kit cars, I had one being a 440ftlb 383 chevy. very slick shift, and never had an issue with it.

Tony, I'd be interested on how the gearchange is with the Fibre rings and bronze bushes. I have a mid-shifter kit to fit for correct position in a TVR and understand there is a selector mod' also that can be done to further improve gearchange. I can't believe the difference in service between here and the States, so helpful.
