Rocketeer Jag 3.0 V6 conversion
Discussion
Sorry for radio silence guys - kit has just been collected by mate today - pallet is now in the back of his truck - which will be unloaded tomorrow with all the kit contents laid out - i will get a photo done.
That means these tall Jenvey air horns & inlet manifold for the 6 ITB's - pictured above - will soon be vacating my desk space and re-united with the rest of the kit. Probably going to start in February but might start sooner...
All motivated again now
ok - apologies - life got in the way - but the engine is in and in about 10 days can collect the exhaust system and the injectors. Quite a few installs have been done in the US and here now - hard to believe i've taken a year to mess about! Anyway when all dry assembled will need to cut hole in bonnet bulge and have to then do dimensions to make a mould - so i can have a clear cover vacuum formed for trumpets. Not sure yet if i want intake aperture at the front or at the back? I am not suggesting ram air effect is relevant - just not sure what is best - which i guess will be trial and error
for reference - here is a pic of the actual ITB's with the shortest trumpets available fitted on the original demo car (which were too short to enable bonnet to be closed - but resulted in insufficient airflow/clearance for trumpets) - i have gone for long trumpets - same dimensions as per the JP1 application - to give all the air needed - but means mx5 bonnet needs cut out.
...really do plan to have it on the road before christmas - (this year!) - should sound good - missed driving the car over the summer to be honest - absence definitely makes the heart grow fonder!

Nice!
I've planned similar (although my v6 fund keeps getting emptied by life!) with irtbs - my thinking was to vacuum form a plenum chamber poking through the bonnet (so stays in situ when the bonnet is raised) with a front outlet matching the throttle diameter of the corvette.
Then, the corvette CAI install kit from Flyin Miata to feed (and filter) air coming in from the rad duct in the bumper...

well only a mere 3.5 years later(!) Got engine running on the dyno yesterday and although we need to fit bigger injectors next week to get the magic number.... 
Video of it running here - not the best run but does not sound too bad
Should go alright with 300/ton and at this rate might be finished before the end of the year!

Probably a dumb question but what made you go for velocity stacks? I know that the demo car used to have them but Bruce from Rocketeer said that carbon fibre intake plenums increased the airflow due to the lack of space in the engine bay for the stacks to breathe properly.
Obviously if you're having them poking out of the bonnet then this isn't an issue but apart from looking awesome, are there any other benefits?
Also, how on earth is 300bhp achievable? Watching this with interest.

The stacks are fitted to 6 individual jenvey throttle bodies - which is quite a different fuelling proposition to 2 plenums. 6 itb's have been proven not to work with a closed bonnet and short stacks - simply is not enough space/suitable environment to get enough air in - cut out in bonnet with longer trumpets solves that problem. (these are the 6itb's from Bruce's original demo car) I wanted the ultimate power/aesthetics and sound that 6itb's provide - it is more or less the set up on the Jaguar JP1. For most who want the closed bonnet/no extra expense and not chasing final power numbers - twin plenum is a better option. As for 300 - well it reached 293.5 before fuel capacity of stock injectors was reached. Larger flow items are now going on it - coupled with fact from the power curve you can see power was not tailing off at 7- suggests there is more to come. Engine was run to 7800 on another run - it's a new old stock engine and seems a good one - so its fair to assume there might be more to come.Obviously if you're having them poking out of the bonnet then this isn't an issue but apart from looking awesome, are there any other benefits?

£12k is a lot dough isnt it..- I'd want a V6 Mk1 personally
No affiliation to vendor and not seen the car but just looked at the ad - it is probably a definite plus re residuals that Rocketeer have done the conversion. Unless you want to do the conversion yourself and have the time - this for a turnkey car all done ready to drive is a lot of car for 12k. Bruce's demo car is a Mk2 and goes really well - he uses it as his daily and although I have mk1 - the mk2 is growing on me. New address for Rocketeer web site is www.rocketeercars.com/ - features Bruce's silver Mk2 on video intro
