Did first trackday of the year in my Westy on saturday at Snetterton....

Felt a little overpowered.... but conditions were hardly ideal!

least it was easy to see where the track went! and yes... if it wasnt slippy enough. Someone dropped lots of oil!

well done to Snets staff and Easytrack for keeping things running on a very tricky day!

Got any vids????

The good think about it is you dont need water injection with that cold
did you hit 2.2 bar?

With The power and torque increase in a chassis you must start to consider what a cars build was designed for. I.e is going to withstand the the increase in pressure being exposed on it?! Remember stiffening a chassis aids in cornering ability as stops undue flex. Putting an engine and supercharger in a spaceframed car to give 400hp and a significant torque increase sounds great but this needs to be considered that can the engine bay take it and will the axle be ripped off the car.. Itll sound great though

I am planing to buy a a widebody Westafield Seight and build a 700HP motor
Yes if you use a Buick iron block you can have over 340 CID and with a TVS1900 up to 750 HP with TA heads
ported the heads flow about 250 intake and 189 exhaust with 15 LBS boost on European 100 octane which is
American 95 octane using a Halteck that can back of HP when wheels are starting to spin the thing should I hope
be in the 0 to 60 in under 3 seconds. It should be a fun retirement toy. I want insane torque.
Comments are welcome. I have a number of other fast toys.
P.S. what is the rear end in a Seight? will it need to be replaced?
The world class T5 will handle the power.

Increasing the weight with a big engine will improve the traction, unfortunately in a Westfield the weight isn't being added in the best place. The best acceleration would be obtained with a 4WD system. It's been done in a Dax Rush, so should be possible in a Westfield.

Superb lurking, BTW.

You would have to be pretty dumb to use an iron block v8 in a Westfield when you could throw an LS9 in there.

Hi there! So you're putting a 700hp motor in a Westfield with an ECU that will back off the power when the wheels begin to spin.
That will be most of the time then!
As regards the rear end then, yes, it will need upgrading. Lots.
I applaud your insanity.

...Although at risk of stating the obvious, the frame will only be reacting as much torque as the tyres can transmit to the tarmac.

I know a chap with a 300bhp Rover V8 in an Seight chassis Westfield. His top chassis rails have just broken..........................

I notice ellipses are getting longer and longer.

This started out as a “how much is to much” in a 7 thread.

Now I’ve read the whole thread most of it has decendid into my willy is bigger than yours (BHP per tonne) and I can ejaculate quicker (0 -100)

Some time I get to 100 prematurely !?!

How much is too much BHP in a 7?

When you can’t go for a quick blast without S411TT1NG yourself.

Holy thread resurrection Batman!

Sorry, but I still reckon my comment from 2012 nails it down fairly accurately - to re-iterate

"If you're talking about a light car on the road then anything over about 350Bhp/tonne is largely a waste of time & money, unless you either have a death wish or don't enjoy possessing a driving licence. On the track you could probably nearly double that with a perfect setup, perfect weather & the right slicks - but try taking the same car out in anything other than perfect conditions & unless you are a very special driver you are an accident looking for a location"

About the only thing I could add to that is that with front engine & rear wheel drive a large heavy engine becomes even more pointless & that you could possibly up those figures a little if you had 4wd - but it still comes back to the same thing on the road, when/where could you ever exploit that performance SAFELY & , indeed in the UK legally

I have 0 - 60 in around 3.5 seconds with just 190 bhp, the full performance has never been explored ............

& as Paul says, much pointless willy waving going on!

An old thread but I'm bored, watching a fire burn....

I had a Westfield with 160 bhp. A narrow. Was immense fun as you could pin it and always have control.

Then I had a 250bhp V8 Westfield (SEight) and it was a total blast. Overtaking that made you laughter out loud. It was only too much until I changed the T1Rs to R1Rs. Before that I'd start sliding the back out whilst overtaking, in a straight line, in 3rd. All controllable mind you. The front end weight ruined the handling mind you.

Then I had a Westfield with a 240bhp na Cossie in it. A proper race car, but it was so we'll set up I wanted more power.

Nothing is too much if you can deal with the weight. It's not about willy waggling. It's about having insanity on tap.

using an iron block buick allows 100 lbs less with supercharger than the LS9
Bolts into place on a Westafield
Fact is I will probably use a 5 litter aluminum V8 using a P76 block and ported buick heads as the Westafield is so light 300 set up for monster torque maybe even twin superchargers and low max RPM
horse power should be plenty and I have an MGB that needs 650 HP
