1.6 or 1.8?

the modified 8v probably wasn't pushing 130bhp. many of these performance modifications are nothing of the sort. at best hes probably got the same amount of power as the original engine head when it was new. engines lose power over time, and these modifications often do more than keep them at the same amount of performance as they originally had.

Not true really, as an engine puts on the miles it will actually be MORE powerful as it loosens up, providing nothing is excessively worn or damaged.

Just to add, i can't see how a carb engine could keep up with a gti in good running order.
I remember racing a friend in a scirocco gt against my vr, i left him for dead quite literally. However he wrote it off and bought a gtx, and that was very surprisingly quick off the blocks, even against the vr.
Saying that though, the scirocco gtx is the 1.8 gti in a mk1 golf shell, and it did have an audi throttle body/sports exhaust and a fast road cam.

I must admit, im not that wise when it comes to rolling roads. Seen a few of my mates put their RS Cossies and Turbos on them and im not convinced of the power they put out.

Do the rollers have resistance on them like a road would? and what about aerodinamics? is that taken into account? A car may have a recorded figure on the rollers but that means nothing in everyday driving conditions?
That my opinion anyway

I'll let you know what the score is when I put mine on in a few weeks!! 

I don't think they do tbh.  Remember seeing an article on an Audi RS6 and that reached over 200mph on a rolling road. On the road I think it was about the 175mph mark.

Rolling roaded my best mates Fiesta the other day at Interpro in Thornbury and it measured 194 bhp and 240 Ib ft Torque.
That was the figure at the flywheel, at the wheels on the road i expect it would struggle to put out 150 bhp 
Still very very quick car though!
Shame about the blue oval!

Thats a lot for a fiesta, whats he done to it?

[Si]

You should of asked what havent we done to it?!
1600cc bored to 1800CVH, lightened and balanced Crank, rods, Mahle Pistons, -31 actuator, port and polished head, stage 2 hybrid Turbo, green injectors, Pace alloy intercooler and radiator, aqua mist, 195 chip, ......i could go on and on! 
The diaphram on the Actuator blew at 130mph and melted a 50p size hole in piston 3, so after a 3 year rebiuld (it took us that long cause were so busy doing other work) it was finished at 194bhp / 240Ib ft. 
Looked like an original RS Turbo aswell and blows away twin-turbo Supras! 5th gear wheelspins?!!! Yep! £14.000 in reciepts!
So all these kiddys in ford magazines that say thier RS turbo with a K&N, exhaust and chip is pushing 200bhp is a load of crap.

Still, they all drive Fords at the end of the day!
Turbo'd rot boxes

What a waste of money 

[Si]

I know, but it does put a smile on your face everytime you drive it   
The annoying thing is, my mate also owns an Audi A4 1.8T, a Mk2 Golf GTI 8v, and a Mk1 Golf GTI 8v. aswell as the Fiesta!
Lucky git!

Up to a point. Then it all goes south as the engine becomes worn out. And lets face it - what GTI hasn't been ragged to death?
