Was a little dissapointing on the day, first run before it was fitted only made 130bhp, 5bhp down on what it made last year when Vince set it up. The only change to the car has been the trumpet being removed from the airbox. With the vernier and some setting up I came away with 137bhp which is better than ever and drives so well so can't be dissapointed with that.

I'm not chasing power figures but I'll be putting the trumpet back in and be very intrested the next time cgti has a rolling road day up there so see if any of my 5 return.

if you just dropped an ABF in it would go even better....

You don't need an ABF in this car. 140ish bhp in an 8v will be good fun!

I can confirm that Ians car is perfectly fine with the engine that is in there, its perfect for what he uses it for and its so easy to drive you could even lend it to your nan to go shopping in!

Was the first 130bhp run done on neutral (stock) cam timing?

More importantly, how is the torque curve now? Any better?

Torque gains are what you will feel on the road!

Refitting the snorkel won't gain you anything. I suspect your missing 5hp was due to timing being slightly out. The fact you have gained 7bhp from the visit and it now makes more than ever should be pleasing...

It made 135bhp when set up by stealth a year ago, driven 1500 miles, snorkel removed, put back on the rollers 12 months later, made 130bhp. So, timing wasn't even touched. I appreciate temperatures, tyres pressures etc can make a difference but was suprised by 5bhp. Not moaning drives lovley.

is the noise as loud as my car?

Sounds great, Not as loud as yours but I like it, just sounds that bit more aggressive.

As Nealey says it is, you can drive it quite normally and you would think nothing of it, but get the toe down and it comes alive, great fun.

Skinty get that valver running and convince me I'm wrong.

oo err sounds like a challenege to me! so what happens when I do convince you?

got to admit it does pull quite well and drives pretty good, just the vibration from the solid mount (at idle) thats a bit of a pain. other wise, credit where credits due

[drunkenalan]

yeah skinty your all torque.. oh no hang on a minute we 8v owners have all the torque!!

[i.a.n.b]

Straight through the mot today.

[nealey]

how many miles has it done since the last one?

[i.a.n.b]

2000. Most I've ever managed between mots in it!

[nealey]

Suppose it has been out a bit more this year! Last year it was stuck at your cousins unit for most of the year!
