Update...

Took my brave pill today and dropped the 100bhp shot nozzles in, did some more logs, NOS setting adjustments and then a quick test with the performance box.

0-100mph in 9.2 seconds off a 5.2 0-60mph.....so that is 60-100mph in 4 seconds flat  :evil:

That is equal to the Ferrari F40 and faster than the Lambo Reventon

The car feels soooooo strong in the mid-range with the nitrous on, but grip is still very much an issue. If I hadn't briefly hit the limiter in 3rd I reckon I would have been down near 9 seconds dead  :laugh:

That's surely got to the one of the (if not the) fastest FWD hatch in the UK ?

When you are not running the NOS, is the ED as drivable and tractable as a normal car or a bit of a handful ?

The car is very tractable and driveable as a normal car. In April I drove all the way to the Nurburgring, thrashed it around the 'ring for 24 laps in one day and then drove it back home. 700+ miles out, 350 miles on the 'ring and 700+ miles back. Remember that my car also has R1R tyres, full suspension and engine/transmission upgrades and a Quaife LSD to help control the power :smiley:

think you need to upgrade from the 100bhp jets  :grin:

you ever thought of stripping abit of weight out of the car to get the times down even more? Sayin that the extra weight pushing down on the tyres may be the difference now of stayin on the road or makin love to a barrier

Rods before 100+bhp jets :cool:

I have thought about stripping the car, but I love my tunes too much and that would mean that the Sub would have to go :cry:

Re: Nitrous injection installed-1/4 mile time up 27/07/2010.

Update...

qtr mile...1st stab.

Had to go a little further afield to a longer,flatter, straighter strip of tarmac to get a qtr mile time up. Only had 3 attempts, and the 2nd one was the best. Trevor phoned me and told me off about not using the nitrous in 1st gear and gave me a few setting ideas to use nitrous off the line instead of revving the engine and using the turbo - definitely worked and is more stable a run off the line. Bare in mind that this was with the sub, spare etc still in the car and just the rear seats out as normal.

Increments to 100mph.

next increments

This gave a best of...
