My car is now too powerful

[Dogbucket]

The TVR Griffith had 2 engines:-

4.3ltr - 280bhp and 320lbft - 1060kg
5.0ltr - 320bhp and 320lbft - 1060kg

Is that all?    My old S4  with its 4.2 V8 had 344bhp - and you probably know how much my current V8 steed has.

So did the AJP engines go in the Griffith? 

Griffiths/Chimaeras have Rover V8s, 2 valve per cylinder pushrod 1950s designed. So no the bhp/litre is always going to look poor against a modern multivalve number. But its all about the power to weight.

The Griffith was supposed to have the AJP and then later the Speed 6 but neither happened. Some owners have retrofitted the AJP to both Griffiths and Chimaeras. Also the Chevrolet LS V8 is a popular retrofit.

The rover V8 is a classic lazy old engine! It's torque curve is flat as a pancake generally, It'll have 260lbs/ft at 1500rpm all the way to 5000rpm. lol! My Dads cerbera has been fully rebuilt and pushed 451bhp on the dyno. Now thats a monster to control with no Traction control! However, In everyday life, he can't even put his foot flat in 3rd in the bone dry ! Theirs no need for so much power tbh. its all pub talk! =] Give me a 280bhp Golf and i'll be happy =]

I rebuilt a Buick 455 cu years ago.
(The Rover V8 was a small aluminium version of this venerable engine.)

510 lb.ft out of the box.

Here is a nice potted history of the Buick/Rover V8:

My lump was cast iron and really heavy, Buick based the Aluminium version on it.

Agreed, the power outputs of the older V8's in the TVR's look poor in comparison to modern engines ..... but try one out to see if it goes well enough 

You don't find many people complaining it is lacking    As has been mentioned - torque from nothing to max revs

So how much is this Quaife for a GTI/Ed30 including fitting and who would fit it? Any known problems?

Good thread guys.

[Hurdy]

A Quaife fitted for a manual will be slightly cheaper than a DSG one.

Look at around £1300 to £1400 for a manual and £1450 to £1650 for a DSG

Not many places do them yet, but the most often quoted is VWRacing/Racingline.

Thats pretty steep.
I would probably only take this route if I had remapped the car TBH....

Would a quaife really make a big difference with a standard GTI/ED30?

[AlanD]

I think you will need to do quite a bit more than just a remap to warrant the money it cost to get a Quaife, money down the drain on a standard one. All imo of course.

[ifti]

Yeh, seems like a hell of a lot.
Dont think I'd ever spend that much on a single part!!......

[SO8]

Just changed back to Superchips newer map for the DSG .... far more power and no problems now we have nicer weather 

Much quicker on the uptake and the TC light is staying off
