421 HP Turbo SHO
Just an update from the 400HP SHO thread,
I got some VP109 race fuel over the weekend and tuned the engine to get the 421 HP
Thatís it for this puppy, boost is maxed out at 1.5 bar from 7000 up.
More ign timing doesnít make any more power, fuelling is smack on.
Ran the standard injectors at 5.5 bar to supply the extra fuel.
Could fit a bigger turbo to make more HP but will obviously loose it from the bottom.
Going to weld some fittings in to measure temp and pressure drops across the intercooler and turbo etc and retest.
1st pic is the HP and Torque
2nd pic is the Torque curve only
3rd pic is the HP curves of previous testing
- Red is stock engine and ECU
- Yellow is C1 Super charger wheel, FF Exhaust and Air filter and Intercooler spacer, also M400 MoTeC ECU
- Light Blue is Turbo set up running M400, on VP109 race fuel.

Nice. I can only imagine what that thing is like. We have an invitation from a fund manager to come over to the Sydney area for business this year, would love to see this thing.

I would love to put a kit together but its a lot harder and more time consuming than most people realise. Places like R&D and Riva do a good job with their kits, everything has to be right and able to be reproduced accurately, you have to make sure it will suit everyones needs world wide, test the bejesus out of it in all conditions, the more parts to the kit the harder it is.
This kit would need pistons, rods, fuel pump, regulator, turbo parts, pipe work, stability brackets, jet unit, drive shaft, parachute , the list goes on and on. It would be a fair chunk of money in todays economy.
We will see how it goes.

Why is the boost maxed out at roughly 22psi? Is it because the turbo your using is to small to produce more boost pressure? How about throwing some propane on that puppy
