Still limited. *Must* get that removed sometime.

No gremlins for me. Brick wall at 112mph. Exactly, according to the GPS system.

Ah the joys of a unrestricted mota!

Have finished the GT4 and been hoon-testing it everywhere.
Has gained at least 60bhp (est) from the cooler and turbo mods.
Instead of getting less urge at high speed, it now just gets stronger, such that at 120mph in 4th, drop into fifth i reckon itll do the clock.....(160)
Will have an uprated pump, injectors and a Motec m48pro soon, so even more boost should be available...subject to piston strength!
Must go down the M6 toll sometime and try it!

Good man. Has the FMIC introduced any noticable lag? Or is it the same as it was?

Hmm pretty much as it was. The larger compressor wheel has changed the power delivery characteristics tho, so that power is available at slightly higher revs than before.
2500 was about where it started to get frisky before, now its about 3100. However, the power is so much stronger and longer all the way up to redline(wasnt before).
You do have to drive it in the band to get the best possible reaction from the turbo, but its hardly a problem. You can just blitz anything on overtakes....had some fun with a wrx....like "can you please get outa the way now?" lolol
Should be an absolute scorcher when the rest of the work is finished. Turbo is capable of 380bhp plus, intercooler at least 600, but wont ever get that close...pity...
Limiting factors at the mo are pistons, injectors too small, pump not enough capability, and management.
Really may change the rods for Arrow "H" section and steel main bearing caps just to be secure...
Have to wait und see.
