give up Ben, no point argueing with the ignorant, plus the amount of cars Stromba has built to take on the SQM big boys means he knows best
FYI Mehdi has a supersprint manifold on the same day as the cast iron valver one, it made a huge difference in that the stainless supersprint one was crap all through the rev range and the valver one was better. no doubt people will have their own theories on this, but tried and tested on the same day and the difference was not only noticable... but massive. Mehdi even phoned Ben in a panick as to why the car had suddenly become dog slow...
Just because a valver or willy manifold may be £500 from Reno does not mean they cost that, anywhere else you can get a mint one for a fifth of the price, only an idiot would pay that. Anyway, where's the science in all this, where's 'YOUR' proof? What testing have 'YOU' done Stromba, or did you mate in the pub tell you this... sorry, I mean mate in the internet cafe... ;)
