Subject: Renault Clio 16v
Sender's Name: Samantha Newby
Question: I'm interested in superchipping my car could you give me some prices please, how much on its own and how much if you fit it, and how easy is it to fit? How much bhp am I likely to gain? Also how much are the kevlar brakes? Can you just buy the pads or do you have to have the disks as well? Scorpion exhaust, how much for the full system?
Answer: Superchip ?165 plus VAT = ?193.88 Fitting ? 30 plus VAT = ? 35.25 (This includes setting up on the Rolling Road) The operation whilst being delicate is reasonably straight forward for those familiar with car electronics. We do however prefer obviously to set the car up on the rolling road following fitting of the chip. Gains in horse power are within the order of 6 - 8% across the range.

Question: I own a 1995 Ford pickup with a 302 V-8. The check engine light keeps coming on then going off. It acts like it is starving for fuel then it jumps like it gets a lot of fuel. When the engine is scanned it gives codes 172 and 173. The exhaust is up to spec. The fuel pressure is also up to spec. The oxygen sensor, EGR valve, and the mass air flow sensor have been replaced to no avail.
Answer: As we don't get involved with the US stuff very much I'm not really in a position to help you. We don't have access to your fault codes . It sounds like a poor connection, rather than a sensor failure, as the reaction from the ECU is extreme.. It sounds as though it's going into limp home mode, which would indicate a total sensor failure of some kind You need to know what the fault codes mean !

Question: own a Cobra kit car with a 2.0L modified Pinto engine and want to fit twin side pipes. Do you know if it would affect the performance if I split the manifold so that two cylinders went through one side pipe and two through the other,the manifold is 2'' and the side pipes are 3 1/2''. One side will have a longer run of pipe than the other with more bends. Or would it be best just to make a tee at the end of the manifold.
Answer: My guess is it would make little difference to the performance. The trick is to treat the gas as a liquid, and imagine how it would best flow. I'm not sure it would sound good on just two cylinders per tail pipe however,my choice would be to split after the pipes have joined up. If you need some stainless bends I can supply them from Turbo Technics!

Question: Hi I have a problem with my 1.8i powered Nova. The car was running fine but recently when started from cold or after a short period of the engine being off it will just crank for ages and then eventually start. Also the idle seems a little lumpy, apart from that it seems to go fine, Ive changed the plugs, leads, dizzy cap and rotor arm but this has not improved the starting probs. Any ideas? The engine is a 1986 Astra GTE 1.8i Unit.
Answer: It sounds like the car is possibly running rich, but for sure it has a management fault of some kind. The best bet would be to find someone who knows how to fix it ! The trouble with this sort of injection system is that there are a great many faults that will cause very similar problems, and you will need specialist knowledge to deal with it. Usually the diagnosis is more trouble than the cure.
 
Subject: Peugeot 306 Gti-6

Question: I currently own an 'R' plate Peugeot 306 GTI-6. I feel it could do with a tune up! ... could you provide me with a price for a roling road session please. I also am looking to fit an K&N 56i induction kit, I don't want to chip the car yet but would be interested if you could provide me with a price for both the induction kit and the induction kit including fitting and rolling road session.
Answer: My personal choice would be to fit the chip and induction kit together. We can supply a chip which will compliment the filter swap. We have found this conversion to be very effective with gains of around 10 to 12 percent throughout the rev range. The Superchip costs ?165 plus vat with the fitting costing ? 30 plus vat. Total cost ?229 all in. The filter would cost around ?70 plus VAT, depending on type.
