vortech supercharing a griffith 500
having recently caught the ebay bug n never having gown out of "performance enhancing" my cars, i am now the proud owner of a v1 vortech supercharger in t-trim.... this followed a lengthy conversation with gav about his eaton 112 n he was the one who directed me here.....
so any ideas on a preferred route for reliability vs power output as i was hoping for 450 to 500bhp.....

You need to check out phils cobra site. For a while he ran a 3.5 rover with a centrifugal blower and I believe he was making over 300bhp with a sensible level of tune. It should be easy enough to get over 400bhp from 5 litres and although 500 would be a little bit lively its still well within the realms of possibility. I cant remember the link to phils site off hand but no doubt someone will post it here for you! Its really an excellant account of his work with the cobra through its various engine guises and contains much information that will be valuable to you during your conversion.

Hi there,
I have the 500 engine in the cobra now and did concider blowing it like I did the 3.5, but its simply not strong enough. The plan now is to fit one of Rbos 5.5L engines and then blow that if I get bored.

...And when you get bored of that, you can stuff 10Lbs into that to make it interesting..
Supercharger.....
hi, thanks for the advice....I do remember reading somewhere about the fragility of the 5 litre under race conditions. What appears to be the problem? and if I were to supercharge it (I promise no more than 9psi) would it all end in tears?

2, Fit mild cam and a few other cheap and commonly available tuning parts of known and well proven quantity.
3, Drive for tens of thousands of fast and furious miles with nary a problem from the motor.

hmmm, whats all this talk about an LS1 then?? What gearbox would it need and how much are they? Thats without all the mods needed to get it to fit, I know its not too hard but its hasstle.
A 5.5L bottom end is around 3.5K, not 100% certain of the final price but its around that. My bottom end is worth 1.5K, so 2K and I have a 5.5L 370BHP 420 torqy things and I can use the current gearbox (as long as it holds out). Then I pop a blower onto it, simple really , for say another 1K,
so why go for an LS1???

Ohh, sorry, forgot to answer the question
the 5.0L TVR bottom end is a little too weak to blow, Im not going to say too much as I want to sell mine, but they certainly arent a strong crank. Mine is good though
