Delilah's heart transplant.

king big hammer"
Drool...Drool some more......
It's a MASSIVE shame that the RV8 won't go in the early chassis (not without a lot of mucking about anyway) and I **SO** want to go for a V8....
But, as I said in other threads, I have this Holden (=Buick) 3.8 V6 and T5 box sat on my garage floor.... and here in NZ and Aus they do a factory supercharged 3.8 option, which I think will even fit under the bonnet.....
Anyway, best of luck with heart transplant, Zig....

Yeah...yeah...yeah...
..."I wish"...As said a V8 wont fit, Well an RV8 wont but a ford 302 will but in honesty once the engine is rebuilt and the supercharger is fitted then i should have a wedge thats running over 300bhp... 
Hope your not expecting 300 BHP from a V6 ?..."I wish"...As said a V8 wont fit, Well an RV8 wont but a ford 302 will but in honesty once the engine is rebuilt and the supercharger is fitted then i should have a wedge thats running over 300bhp...

Well im not going to get too excited until its rebuilt but the guy that will be rebuilding it is John toovey and he is known for his work on V6 cologne's...Its being built to race specification and should be pushing over 200bhp....Then when the supercharger is fitted it should be pushing up to or over 300bhp..Then with a squirt of NOS..Well enough said...Just have to wait and see..Should be ready for next years BBWF...Ziga

What are are planning on doing for heads? Grady
Hi Mate...Not too sure yet but unleaded conversion is a must..Some port matching and polishing possibly big valves If they are needed...The supercharger kit is set up for stock parts but i will be talking to Mr toovey nearer the time to see if there is anything that would benefit the enigine and work in harmony with the blower..A blower profiled cam is being added to the list especially if the old one is wearing and will need changing anyway..The main thing will be making sure the engine is strong enough to cope with the extra horses..Cheers..Zigamrzigazaga said:

i doubt with the standard head castings you'll get that much Zig 
just over 200 with the supercharger maybe, but the heads on the ole colognes give up good and proper with boost and crack due to thin wall castings 
i'd expect around 200 S/C and be pleases with the smooth torque range that it'll have

Toovey engines can produce in excess of 200Hp normally aspirated, however, this would be with a tricky cam that would be totally unsuitable for forced induction, but with a cam suitable for boost and a supercharger...... just over 200 with the supercharger maybe, but the heads on the ole colognes give up good and proper with boost and crack due to thin wall castings i'd expect around 200 S/C and be pleases with the smooth torque range that it'll have
When running forced induction you have to ask yourself what power you want then work out the highest CR you can run, so to maintain drive-ability. Little point having 400Hp with so low CR drive-ability on the roads would be bad.
BBWF 2012 the highest rolling road figure of the day was 275.9Hp..............From a 2.8 V6 with standard CR.
This engine (turbocharged) has been producing well in excess of 200Hp for the last 30 years without any head troubles, and with standard CR remains as drivable as any 2.8 when off boost.
Obviously it's far from the best engine in the world, but Zig wants to stick with a V6, I for one admire his plans, as its in the spirit of TVR and how the factory would likely of done things, and hope he's happy with the results.

Zig, I am really sorry to read about your engine woes. You have done so much with that car, it's such a shame. Can I suggest you speak with the guy who looked after my Cologne 2.9 12v V6 race engine? He is an expert (yes, he really is) with Ford V6's, his name is John Toovey and is based in Cannock. He will discuss your options and offer prices accordingly. His prices will be no where near what you have been quoted. The biggest bill I've had off him was less than half you have been quoted and that included 6 forged pistons, big valve conversion, decked heads and block, scary cam and all new bearings as well as a host of other stuff. That engine ran 250bhp at 7500rpm! It's well worth a chat with him before you make your mind up. He may even have a built engine just sat on the shelf.
Thanks chris..Optimism is a good thing...As you can see by Mr Chant's post its not impossible to get over 200bhp out of a V6..The guy that owned the kit before me sent me one of his friend's email addresses and i have conversed with him over quite a few issues regarding the supercharger kit..His sierra is pushing 223bhp on stock parts and thats with a big 4 door metal shell to lug about...Next year will be the telling factor...cheers...ZigaEdited by mrzigazaga on Sunday 30th September 20:02
Or run a bit more boost for intresing results Click
575Hp at 1.6 Bar boost = 221Hp at atmospheric, very good with a cam suitable for a boosted application.
I would guess unsuitable for a road application due to a likely low CR, great when its on boost but gutless when not.
Have you found out the maximum speed, volume, pressure output spec. of your blower yet? From there you can calculate what you can expect.
