RV8 into a MK chassis
Hi All,
I just spotted a note on the MK web site saying that the RV8 can be fitted into the MK Indy chassis. After speaking to them I was told that this is
correct and that the chassis requires no modification, however I must use a Ford Type 9 ‘box as the Rover LT77 won’t fit the transmission tunnel.
Is this true? Has anyone tried it? And does anyone (A), know the max power and torque that the type 9 will take and (B), what the adaptation to fit
the RV8 entails?
Nothing in life is ever easy…

Max,
I've done the V8->Type 9 conversion for my Dax Quadra. Abbey SPortscars www.v8tuner.co.uk have the bellhousing you're after burried
away in their site. Not cheap at #275, but the most reliable way to do. it.
The Type 9 don't like bags of power, but it'll hang onto a V8 pumping out 135bhp. Most of them go bad through oil leaks that the owners never
check/top up. If you want more power, either keep a spare box, or get a recon job. Better yet is a set of BGH Geartech gears for the case. Brian
rebuilt mine to take 300bhp and added an ali top cover for a grand.
Abbey also supply all the bits you need (clutch bits are off the shelf at hellfrauds)

Surely it would be easier to modify the MK tunnel to accept the standard LT77 box (and lots cheaper). Also the LT77 is capable of taking the power and
torque of a tuned RV8, mine does. I guess it might fail eventually but getting them fixed is not too expensive

Hmmm,
The intended V8 has around 250BHp, sounds like the Type 9 isn’t going to take it. The reason I was interested in the MK chassis was it meant I didn’t
have to mess about altering the lengths of the wishbones if I made my own chassis and used a Capri LSD. Not sure I like the idea of spending £££’s on
a pre-built chassis and then start cutting it about, might be better making my own after all. Does any one know of chassis plans that are wide enough
to take the RV8 but will accept Ford Sierra IRS and standard IRS chassis front wishbones?
I was giving the 2nd edition of RC’s book a quick peruse and I noticed a little note in the SVA chapter about air filters and being no higher than the
bonnet line. Is this the case? If so, does it also cover the engine being no higher? My injection plenum top will be poking through the bonnet like
the D@x’s, is this going to be a problem?

Absoloutely not. A hundred happy customers with SVAd cars can't be wrong. If you're paranoid about the radiusing, grind down the flutes along the
top of the plenum and give it a paint.
As for air filters, that's cobblers. I have a pair of ITGs running most of the length of the bonnet that stick up a good three inches that weren't a
problem (as long as they have the correct radius).
As to the type 9, if you want bought chassis, and you don't want to cut it up, then the only option is a beefed up Type 9. Having said that, there is
one member of the Rush OC that runs a 330bhp Cossie through a type 9 into a capri axle without any grief. It's all down to how you treat it.

said loads a times but, remember the cars we run are a fraction of the weight the gearbox's, axles are designed for, hence they are well under
stressed, i can do doughnuts to my hearts content thru a bike box, you would have to be an absolute animal for years to blow a type 9 box in a 7, or
unlucky....you aint got the traction, full stop.

I don't know of any published plans for chassis with Sierra IRS, probably because unless you got the Robin Hood route then wishbones and uprights are
going to have to be fabricated, and each firm that does that does it differently.
I can't see the problem with widening the tunnel to accept the LT77 box. Surely anybody contemplating constructing a whole chassis could cope with a
bit of hacksaw and welder work?

Yeah, but if Max wants to buy his chassis, then I see the hesitation of hacking it up just to fit a different box.
I reckon a Standard Type 9 will be fine, as long as you pick a good un in the first place.

I wasn't suggesting he hack up the chassis, just modify it.

I see Luego are now producing a V8 chassis that will accept the LT77 box. A week ago I’d have been delighted about this but now things have been
further complicated by being offered a Fireblade engine & ancillaries at a stupidly low price.
C’mon guys, help me out here: RV8 or Fireblade???

you know my answer don't you ?
nothing wrong with either route, both make nice tunes,
but for ease of fitting, speed, n fun go bike......
what about QR couplings, swap to suit your mood,
if your not going bike, would it be possible to mail me off list the bike engine details, price, year, locality, i may need a spare if the NOS goes
pear shaped

I'm all for using a big engine (3.5 litre BMW six here), but on this occasion I have to say that if the bike engine is the right price go that
route.
You listening Jon? I said go for the bike engine.

Take a look at the other thread where I worked out power to weight ratios for engine powers.
Im not building an exact seven replica, so i went for a ford colgne v6 cos i liked the idea of a six.
However, if you are gonna build a proper seven - low weight minamalist car, then its surely gotta be bike engined? You wont get as much power in a
small light package anywhere else.
A couple of my mates at work have cbr600 and a suzuki 600 - and that kinda engine sound would be great in a locost.
Im gonna have a burbling V6 tho...
do you want frantic speed, or torquey toring capability?

Well the decision's been made for me, got some insurance quotes...
£500 fully comp for the Fireblade, won't quote me for the V8.
Serves me right for being 23 eh?
Bike it is!
