Mental..
Jamesc - 22/1/15 at 10:18 AM

I'm sure some of you have seen this for sale, but it looks mental!

I wonder how it would handle and what the total weight would be?

Tiger kit car

It is basically this

Weight 550kg and 0 - 60 in 2.9 seconds.

Pretty mental. The finished car was on eBay about a year ago - I think for around 15k if I remember correctly.

I was tempted, but it would be a lot of work getting everything running in sync and making it road legal..

Not a bad price though!


CosKev3 - 22/1/15 at 12:46 PM

Like that

Fingers crossed someone on here buys it and builds it.

It is fundamentally different from the Z100 referred to above - it's 4WD.
The Z100 had a Z Cars transfer box to the rear wheels. Had great potential on the competition scene, but it never seemed to appear to deliver (that's my opinion only of course). Devastating is a straightline 0-100-0. Mind blowing thing.

This must be quite a rare car, love the Sierra front diff. I'm thinking quite heavy, room for some modernisation, particularly in the engine department. Would take a lot of work to get it the way I'd want it, but again, that's my personal perspective, worth nothing to anyone.

One helluva project :-)

Love the way the front end has been done very clever.

In terms of weight it would be standard bec (5oo kg ish) + extra engine + extra diff + extra exhaust + drive shafts. But it would have around 300 bhp and 4 wheel drive, I don't think much would touch it.

If I had the space and it was priced more around 3K I'd have a crack at it.

The fastest and last Z100 was twin gsxr engines,4 wheel drive.


Slimy38 - 22/1/15 at 05:58 PM

Didn't Tiff Needel blow one of these up due to sync issues? Maybe one of the earlier 2WD Z100's?

edit: yep!

I wonder how emissions would be calculated... Would they test each engine on it's own, or combine the values to get a 'car' value?

Why use 2x rear diff? Surely it would be better to use a front diff off a 4x4?

Yes but the way the engine is mounted wouldn't it turn the wheels the wrong way ? Could it cope with the power ?


JoelP - 22/1/15 at 08:03 PM

I was pondering something like this the other day, when someone mentioned that bike engine that was button operated gear changes. That would be the perfect way to keep them both in the correct gear. Plus I *think* that slipper clutches would prevent over-revs anyway. I think you'd struggle to stop the front wheels spinning.


JacksAvon - 22/1/15 at 08:08 PM

From memory,

Update.
Tiger have no knowledge of making this particular car
the bike expertise would have been supplied by Chris Allison
the record breaking car was cut up
the last twin engined car sold by Tiger was a Z100, sold to a lottery winners some years ago, the same car was on ebay last year.

With regard to the competitiveness of the Z100 and Z100WR.
Really these were interest pieces.
With series/championship regulations as they were/are, there was really nowhere for them to run.
Even Sprint and Hillclimb reg's did them no favours.
Both cars were blisteringly quick at the time.

Currently, the only place you could possibly run this compatitively is BARC's North West Sports and Saloons
I would love to see that

Would the front diff run upside down?


Jamesc - 22/1/15 at 09:43 PM

Anyone remotely tempted?

Would be awesome to see it on here and get finished. If I wasn't half way through a build, I'd consider it... Unless anyone wants to finish off mine?


Ben_Copeland - 22/1/15 at 09:44 PM

Surely running the front diff backwards will shorten it's life significantly ?


dave_424 - 22/1/15 at 11:39 PM

The front diff runs through the sump of the engine doesn't it so some serious modifications would be needed to get suitable shaft outputs

Isn't it upside down not running backwards? Not sure if that would affect its life span with oil level etc

I reckon this would spin its front wheels something cronic and understeer too if the front engine wasn't kept in check. Maybe some sort of rev limiter to pin the front engine back to the rear engines revs or just above might help?

No, its in front of the engine, direct drive.

Yes your right, I see it now... the front engine is also pointing forwards and direct driving the diff. Not sure how you'd ever get that to synchronise properly??

I suppose if you blocked up the breather and refitted it on top, then were very careful of the oil level inside. Then guess it might be ok.


wylliezx9r - 23/1/15 at 10:27 AM

The way the car is set up 50% of power is going to the front and 50 % to the back, I cant see any issue or am I missing something ? And the torque is piddly.

I meant if you wanted to change it for the front diff from a sierra, that I believe runs through the sump does it not?


Ben_Copeland - 23/1/15 at 10:39 AM

Yes it does in the sierra, I'm assuming they went this way as the front diff wouldn't work.... who knows?

Isn't that was Ultima/GT40 replicas do with the Porsche G50 gearbox i.e. run it upside down, same idea ?


rdodger - 23/1/15 at 11:41 AM

You wouldn't be running a sierra front diff backwards, just upside down. That is if you used a front diff not a rear diff as in the actual car.

The rear diff is fine in the front as it runs the correct way just upside down, just sort the breather and all is well.

I personally would be much more concerned about the solid coupling at the front

Weight transfer?

Look at what 4x4 'supercars' generally aim for, more like 70:30 or 80:20 rear biased.


stevebubs - 24/1/15 at 09:04 AM

I remember the original WR from the first time around. IIRC it needed some serious Motec electronicery to make it go round corners...

the mental thing about having 2 bike engines...........2 clutches to replace every 100 miles!!!!

If you are referring to the one Tiff used, then it definitely didn't get cut up. It's sat in my friends garage.
