Question: I own a Renault Clio 1.2, what benefits would I gain from a rolling road session?
Answer: The main advantage of a rolling road, is being able to test the engine under load conditions, you can simulate any speed, any load, and check timing and mixture levels properly. If you want to try any performance tweaks, you can see the results. A good example is air filter swops, where you can test to see if what you plan is going to produce any more power. Apart from anything else, it hardly costs any more than doing it the hard way, with a session costing only ?30 plus VAT. Try us sometime, you can ev

Question: Hi, I spoke before about my suzuki gls 1.3 I have finally convinced my dad to let me flog the shitty suzuki for a fatser. I have found a mint series 2 rs turbo which is ?3000. It is completly standard. I have about a grand to spend on the car, I want this car to be fast. Please give your best ideas and views on modding the car. PS. do you think it is a good move going for this car? are there any other fast small cars out there?
Answer: An RS Turbo is fine, and all the better for being standard, as most people get the mods wrong! Stuff like induction kits and dump valves do nothing for power: chip the car with an uprated intercooler, expect 175 bhp, with lots of mid-range power. Spend the rest of the money on the front brakes, and handling, with a set of polyflex bushes to sharpen up steering response. Don't lower it too much!, no more than 35mm, and forget 17 inch wheels!

Question: I have a Vauxhall Astra 1.3 ( G Reg ) with pipercross bolt on filter. If I have a ?35 tune at your place, how many extra bhp can i expect approximately, i know its hard to tell) and approximately how long will it last.
Answer: The simple answer is ...no idea !...it depends how far out of tune your engine is. There is only one way to find out for sure, and that is to get it tuned on a rolling road ! I would expect to find something wrong with it, and what ever it is, it's sure worth ?35 . Your car has electronic ignition, so it shouldn't wander too far off if it is set up properly. Obviously things can go wrong with any car. Go on, give it a go!

Question: I've got a 99 Fiesta 1.4 Zetec and find the mid range torque appaling. Have you got any suggestions for tweeking this car.
Answer: I would suggest a Superchip flash module to improve mid range response. In truth, most 16 valve engines tend to suffer from poor performance at the low end of the rev range, in return for a good power output at high rpm. Superchips have developed a module processor which fits into the serial port on the vehicles ECU, allowing the required changes to the ignition and fuel curves. The device costs ?165 plus VAT.

Question: I have a pipercross filter with a crank vent. Where does the crank vent go?? Its for a Mk2 Astra 1.3.!
Answer: The crank vent connects to the large bore pipe that would normally connect into the original air filter. We suggest you just secure somewhere tidy with a cable tie.
