Which mod gives the best bang per buck then? What are your thoughts on this? I'm sure a fair few newbies would be interested to read the comments on this subject
bolt on supercharger for nasp engine! seen these on a 1.2 and 1.4 clio and the bhp increase is amazing
Surely there's a lot more to it than just 'bolting on' a supercharger?
That has to be one of the best free mods you can do. Or replace parts with lighter ones, this will help all aspects of performance.Strip out weight from interior. Cost = free.
of course but it remains a fact that factory cars are not mapped for max performance - If they were a remap wouldnt help .
A few cars (the first 230 kompressor slks for example) had maps that were very close to opimum performance (have one so I know ) This might be because it was supercharged though its far more likely though it was stats again because mereceds thought power numbers were more important than mpg (which wasnt bad anyway being supercharged)
Adding a bigger turbo to a strong engine makes lots of power. 700 BHP supra upgrade for example from a map and turbo, that's quite a gain for a few thousand £'s!
The engine internals are often the limiting factor when it comes to ramping up the engine's power output. VW group has a 180 (ish) bhp 1.4 litre engine but that doesn't mean you can bolt 73 turbochargers onto a 1989 1.4 Fiesta and achieve the same result.
A Supra guy told me the Supra first was ment to be a 600HP supercar, but when it got into production the de-tuned it in 300HP, that's why it's easy to tune it.
Tell your supras buddy that the bit about the supra being designed as a 600hp car is Im afraid........................... nonsense.
At the time there was "gentlemens agreement" in place at that set a declared bhp ceiling of 280 . This was to avoid the government taking action to make it a law so no 400hp cars were designed let alone 600.
Its true that most of the top of the range japanese sports car could be easily tuned for more power but thats not quite the same thing .
GTRs for example had a plastic "reducer sleeve" in the boost pipe which seemed as though it had been designed to be taken out . Power would then be raised but only to about 320 max.
The supra was the strongest in stock form and the bottom end can certainly take 600 but you need to do a fair bit to the motor to manage that and then an awful lot more to the car itself.
When Ford were looking for an engine to power their proposed Souped up Sierra, they popped into Cosworth and spied their experimental project of fitting a double overhead cam head on a Pinto block. Ford liked it but considered that the 300bhp it was producing too much for their target buyer so it was detuned to 204bhp. Now this engine IS easy to upgrade to over 300bhp with new injectors, a modified ECU and a few other tweaks. It is now difficult to find a standard engine
