best engine for high power/weight ratio? AKA Ben's Cab

ambrose89 · 1st June 07, 13:29

not looking at doing it but whats the best engine to drop into a mk1 or 2 golf to give a really high power to weight ratio?

cant be anything crazy like a w12

say it has to cost under 3000 for the lump
would it be an audi 20v, vr6 with turbo. 1.8t?
maybe a volvo t5?
other makes of engine?
bike engines?

any ideas?

mk2 is heavy for a bike engine, but at 70kgs-100kgs the engines are very light

a LS6 corvette engine is small, light and makes 300odd bhp, but i bet all in a turbo'd 20v will win

what's Bill's 450+/tonne not much that will stay with that

Fiat/Lancia Twin Cam.

Go for a 16v Turbo from a Lancia Thema. You can buy a whole running car for less than £150.

They are the same unit as the Delta HF Integrale 16v (different exhaust valves but that's about it) and they are good for 300+ bhp with very minor tuning work.

just seenthat german mk2 vr6 turbo with 607bhp posted on here, i guess that engine in a mk1 would be pretty crazy?

this one

Collie · 1st June 07, 14:18

10.4 1/4mile That is seriously quick

kerrly · 1st June 07, 14:27

there is a golf in golf+ with "only" (used very loosely) 360 odd HP from a 1.8 20vt and its just set the standard for the fastest front whell drive 1/4mile!!!!! surely that would be enough

ambrose89 · 1st June 07, 14:34

would it have a higher power weight than a vr6turbo?

geany · 1st June 07, 16:32

a VR6 is a heavy engine i was advised by a VW specialists not to put one in a mk2 but loadsa ppl do it, i would say 20vt all the way hopefully next year

seb'16v'bonizzi · 1st June 07, 17:12

anyone seen the new golf+ with the REAr wheel drive mk1 turbo'd hyabusa
now that is cool! extremely quick!

e12_mat · 1st June 07, 20:40

Big power 20v with 02m and rear haldex diff,

loads of power and grip!

HIGHLINE · 8th July 07, 10:19

How much cash have you got to spend ?

A VR6 turbo aint that cheap to do !

Ian Carvell · 8th July 07, 11:11

How much would an RS6 motor cost....its effectively two 1.8T motors on a common crank so must be lighter than two 1.8T motors.

Probably good for 750bhp.

4x4 probably required though!!!

HIGHLINE · 8th July 07, 11:24

You can get 750bhp out of a vr6 easy !!!!!!!!!!!

fthaimike · 8th July 07, 15:10

If it's that easy how come there aren't loads around?

Try looking on the net !

Schimmel performance have had 516whp on a stock engine and over 700whp with out to many mods !

I have a vr6 turbo that i built on my drive no roof no help it does 407bhp and 407ftlb torque with more boost to go !

Its that easy !

So you are just over half way there...

That is like saying 300bhp is easy from a normilly aspirated 16v motor because you have got 160bhp.

Over 200bhp per litre is never easy.

Yes but i built mine to drive every day not for the biggest bhp figure i could get !
Theres a big difference !
Plus mine could do over 500bhp easy with no more mods just more boost but why its front wheel drive !

Ian Carvell · 8th July 07, 17:10

Still got to find another 50% more power.

Sometimes more boost means less power if you cant get the airflow. I would think these quoted horsepower figures are as a result of massive boost which will heat up the turbo in seconds and result in far less power in reallity.

You sem to be the expert on vr6 turbos
Ive only built one !
My car has a GT3076R running 1.3bar its not even trying mate !

mk1steve · 8th July 07, 17:20

yes i believe ian carvell knows bugger all about engines or anything for that matter

fthaimike · 8th July 07, 17:23

pmsl

"Ian Carvell" try searching for that on the net

Ian Carvell · 8th July 07, 18:17

I dont know anything about turbo charged VR6 engines....and I hope you dont think I am attacking you, because I know how these posts can sound impersonal.

However, I do work as a Engine Design Engineer and I have worked on a Supercharged 4.2L V8 engine, and I know how difficult it is to get 450bhp, and its the last few bhp that are the most difficult.

As I said..more boost doesn't always give more power...it will to a point, and then you get caught out by thermo dynamics.

I am sure if you ring the company you were talking about and asked them for 750bhp they definitely wouldn't use the word "easy".
