FridgeFreezer Posted April 8, 2015 Share Posted April 8, 2015 This is just too silly not to share, he never really explains why he's doing it this way but you've got to admire the effort / batsh*t insanity of the whole endeavour: http://www.speedhunters.com/2015/03/thors-hammer-the-mg-gt3s-accelerated-evolution/ and http://www.speedhunters.com/2014/09/im-sorry-youre-going-mgb/ The aim is a high-revving, four-valve-per-cylinder, quad-cam V8, strong enough to take a pair of turbos further down the line and 650hp per side. Fitting the two major parts together would be a challenge. The bolt patterns were completely different, the cams in different places, they had different firing orders… the list goes on.

elbekko Posted April 8, 2015 Share Posted April 8, 2015 Wow! I'd read about someone wanting to put these heads on an RV8 a few years ago, but I never knew he actually went through with it. :wub: Quote Link to comment Share on other sites More sharing options...
landroversforever Posted April 8, 2015 Share Posted April 8, 2015 I love the shear bloody mindedness of something like that. Probably loads of people told him it couldn't be done, but he still went ahead. Totally bonkers, but kudos to him Quote Link to comment Share on other sites More sharing options...

Bowie69 Posted April 8, 2015 Share Posted April 8, 2015 Didn't realise he had got so far, knew of the project from years back, like Ross, but assumed it had disappeared into the ether. I do wonder if it might have been better to start with an engine that would do that kind of power without too much difficulty, like a race-proven Lexus V8 instead, or even just an LS3 with twin turbos. I guess it is just one of those 'because I can' projects though Quote Link to comment Share on other sites More sharing options...
need4speed Posted April 8, 2015 Share Posted April 8, 2015 It's all very well doing a "because I can" project. But boy is it a waste of money.... I agree he should have started with an LS* Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted April 8, 2015 Share Posted April 8, 2015 650 per side is not out of the realms of possibility, the Audi 5 cylinder 20V turbos have been known to make over 1000BHP from 2.3 litres... And even the lowly VW group 1.8T engine over 900BHP Quote Link to comment Share on other sites More sharing options...
landroversforever Posted April 8, 2015 Share Posted April 8, 2015 Especially with the new heads, am I right in saying the heads are a big restriction on the RV8 normally? Quote Link to comment Share on other sites More sharing options...
elbekko Posted April 9, 2015 Share Posted April 9, 2015 Especially with the new heads, am I right in saying the heads are a big restriction on the RV8 normally? That's certainly what the article claims. Quote Link to comment Share on other sites More sharing options...
missingsid Posted April 9, 2015 Share Posted April 9, 2015 Kinda similar to the mad Mini project on YouTube that we love to follow. I get that the engineering challenges can lead you astray etc. but surely a 3.5 Lotus or bike engine based V8 would have been better as he wants an engine to rev like a bike engine that normally means a flat plane crank which the Lotus V8 has. Then again who doesn't love the mad bike engines that have been created in UK garages, Kwak Zed V12. 5 cylinder Kwak two stokes, V twin BSA, Enfield and Nortons. As I'm on an i thingy I did not read it all so what country is this in? So mad and misguided maybe but fair play to him. Marc Quote Link to comment Share on other sites More sharing options...

The article did mention a custom crank, so maybe it's a flat-plane RV8? Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted April 9, 2015 Share Posted April 9, 2015 Yes RV8 heads are where you spend the money if you want outright performance, Wildcat heads were the best you could get, but they are new castings/billet (I forget) and a lot taller, and most noticeably a lot freer flowing. What I didn't realise was Wildcat engineering has been acquired by ACR Automotive! http://www.automotivecomp.com/news.html £11k is not as much as I thought it would be fro 400BHP from a RV8.... still, it would be a lot cheaper to get it from a modern aluminium V8 with a turbo or two.

ian_s Posted April 9, 2015 Share Posted April 9, 2015 looks like a flat plane crank to me Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted April 9, 2015 Share Posted April 9, 2015 Yup, that'd be a flat plane crank Did you know, Audi took their stock V8 cranks, which aren't flat plane, clamped them all which ways from sunday, and then squashed them in a press to create a flat plane crank so they should take it racing in the DTM? There was a load of controversy over it, because the other manufacturers couldn't believe it could be done, but Audi proved them all wrong. Musta been pretty strong Quote Link to comment Share on other sites More sharing options...
landroversforever Posted April 9, 2015 Share Posted April 9, 2015 That's cool Bowie . I guess if the crank is forged to start with, the material should be pretty 'pliable'. Quote Link to comment Share on other sites More sharing options...
missingsid Posted April 10, 2015 Share Posted April 10, 2015 I liked the story of early BMW turbo F1 engines, take a road going four pot block and leave it out in the rain for a year or two and alledegedly the worker uesed to p*ss on it as well? So back on topic as I said, Lotus already made a flatplane crank V8 that was fine for GT1 racing so why do all this? Off topic again ish, I once saw a road going Elise GT1 in the car park at Brands, it was one of seven GT1's made to be raced and rebuilt by a private owner completed from spares. He valued it at £1M as he thought only three remained, but then he would I guess? Marc. Quote Link to comment Share on other sites More sharing options...
