I found all three stages of boost interesting and worthwhile.With the low boost, it allowed me to learn how to drive the car well with an extra 90bhp over standard and I honestly felt shortly after the conversion that I would never need any more power. However six months later I was bored with 260bhp and turned my attention to building a high boost engine. I found this was awesome and really suited pretty much everything I wanted to do with the car, the power balance felt right. However, when the option came up for super high boost I felt that I'd come this far and might as well go the full hog and so I did. Interestingly, I found it better on the road, especially fast twisting roads where mid range was most important, however I felt I lost a bit low down and top end which made the biggest difference at places like Prescott Hill and the like, where the high boost was certainly better. Overall though, I prefer the super high boost for all road use and as that is where the car is used (albeit occasionally) it works well for me. ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone |

Unless it's with someone else's Money Manthos I don't think much development will happen ....Rich may disagree but how many people really would pay to have that done ?...maybe 6 on here ?Would it be wise to do it on a engine with 90/120k ....my view is no |

Is there a measurement that equates to BHP with the restriction ring? A certain size give you XXXBHP etc?I'd happily chuck 300BHP through mine once it's up and running, only a engine after all! ________________________________________ 205 Van SC'd GTI6 - because why not309 Goodwood V6 - sold 205 Rallye GTI6 - Bent |

Damien I agree with welshpug as long as the block has been looked after it doesn't matter too much how many miles it has covered you can change all the external parts ________________________________________ Team SUPERCHARGEDI LIVE FOR THE 306 Old Project thread Clicky: [url =http://www.306gti6.com]click here[/url] remove the space between [url = |

I don't often disagree with you Mei But Valve stem oil seals / piston rings / crank seals / cam seals / big end bearings & float etc etc wear guys ...are you saying a well looked after low mileage car say 90k is no better than a high mileage say 170k one ?.....totally mad ... Mines on genuine 120k miles but had all the head gasket & valve stem seals done at 90k ...thank god ...maybe not looked after Manthos ....it's the internal parts I'm on about |

I'd happily chuck 300BHP through mine once it's up and running, only a engine after all! Not exactly as there are lots of parameters that effect this. It doesn't take much though... the low boost runs a restrictor of around 38mm, the super high boost cars are on 50mm and that gives up to 450 BHP. ________________________________________ Contact Details:rich@lynxpowerengineering.co.uk 07732 822546 |

I guess at the end of the day if the engine is standard and it s**ts itself, you've not lost a huge amount? New engines can be had for ~£300 and I guess the worst case is somehow a piston fires itself out of the block and through the supercharger!________________________________________ Rallye Race Car |

A turbo fixes all the above which is what ive been saying for years. The only extra things u need over a high boost and super high boost is an exhaust manifold and a down pipe. ________________________________________ |

I disagree because with a turbo you have to change the internals and make it a low compression engine from the start. They both have there benefits. Personally I think a Low boost with LSD is enough for a gti6 get the handling sorted then just learn how to drive it properly and it's enough on a track ________________________________________ Team SUPERCHARGEDI LIVE FOR THE 306 Old Project thread Clicky: [url =http://www.306gti6.com]click here[/url] remove the space between [url = |

As long as the boost is low you can run it on standard internals regardless of what method of boost you are using. Yes I see loads of type r engines with low blow turbos on them and are absolutely rapid. If someone did a bolt on kit for a reasonable price ( not from DP price) then that's the way I would have gone. But depending on how it's setup turbos make more boost lower down particularly if it's VGT which the rods can't handle. Less revs = more load. So not sure how the standard rods would hold up. I know a couple of civic type r owners who have found out how cheese like the rods are when boosted But what puts me off is sorting out turbo relocation and downpipe and manifold etc as well as feeds and returns etc. It's obviously doable but takes a lot of time effort patience etc to do it yourself like Chris has. Come next year I would be tempted by testing out slightly more boost on a good quality thick head gasket with less compression. I do hear tales of some of the lads in Holland running 300bhp on standard internals with turbos. So I'm sure it would hold fine. Think I would put ARP rod bolts in for good measure tho. ________________________________________ Black power baby!
