1.5 G40 RR result

[Nick_S]

I went to the CP rolling road day at Aldon yesterday and decided to put my mk2 1473cc on the rollers. It's not setup properly by a long shot, but after sorting out a slack brv linkage last week and feeling quite rampant on the way down, I decided to see what benchmark figure it could get for an improvment on.




179bhp and ~170 lb/ft torque was a bit of a surprise. Apart from a full JPPP exhaust system and 'worked' engine, its only producing 8-9psi boost, on a SNS stage 5 off the shelf chip, standard throttle body and intercooler

That was the first run on the rollers which i told them to keep well away from the limiter (charger not had a service for 5 years). It was still pulling top end, so they ran it again to over 7k rpm and it got over 180bhp, but they didn't save the plot (maybe because you only pay for one power run at Aldon?)

Well pleased Just need to sort out a custom map now and refit my G40 gearbox avec Quaife diff.

Nice one Nick, Really looking forward to seeing your new creation in the flesh

Awesome Nick. Should be a real beast when its set up properly... cant wait to see a power figure for that!

179bhp eh?

so at the polo show when you came and said to me 'mine will produce more power than yours' was.......well a lie...........lol

not bad for a unmapped engine though to be fair, only 15bhp more needed now coolant boy!

Nice torque curve.

[Robin]

a full JPPP exhaust system

JPPP?

Thought you got one of Yoof's exhausts?

[Nick_S]

One in the same. Had to go on their ramp for a refit of 2" out of the rear section to fit on the mk2.

May not even be that much

Really good power nick, A remap will make it even better.

[hayesey]

there must be so much potential for improvement there, put a bigger blower on it, boost up to 20psi, remap..must be WELL over 200bhp then.

lol from 8 boosts to 20 boosts! lol

[hayesey]

well exactly, lots more power to be found.

Though as we own the jig, you have to get them through Polo-PP either way... 

Man up and stick a proper blower on there! Should be able to get 190-195bhp out of it with the G-lader and Aquamist - only limitation will be the G40-lader.

When you say bigger blower are we talking g60 or somthing entirely different?

[Andy]

If I had to stay supercharged I'd stick a G60-lader on there like Tony Lo's 1.5 8v.

[Nick_S]

Cheers for all the comments.
A remap should see it get into the 190's and we'll see where we go from there

Last i heard Tony Lo's mk2 was a 1.4 8v. A G60 would get it near 230 bhp with a few transmission casualties along the way
