Question: Hi Alan, Just getting things ready to bring the car up for another mapping, Ive put the vf35 on, i was wondering if its worth going front mount at this stage or stick with the large tmic i have on already? Also i\'ll be having u guys put my pink injectors in, How much would it be to fit a new set of plugs at the same time? and do you keep them in stock? cheers
Answer: Hi Jord - I've no doubt you'll end up with a front mount sooner or later! We can set it up with the top mount, but it will restrict the boost we can run. We keep the plugs, set of NGK PFR7B around 30 from memory. See you soon!

Question: hi alan, thinking bout running my car on methanol mix, coz im gonna start to track it a lot more, is this much to do, an is it a big cost, im running a impreza wrx 320 bhp, its got front mount, 550cc injectors simtec ecu etc, also how much more power increse will it give me, cheers chris
Answer: Hi Chris - We tend to see an average of 25 bhp extra from meth mixes. With the Simtek, you have the option of switchable maps to run on meth/no meth. Be very careful when handling methanol, and make sure the mixing is accurate, or you can come unstuck! No doubt your mapper will advise.

Question: 2.0 DOHC engine. I have removed this engine from a 1992 sierra and fitted it into VINDICATOR SPRINT KIT CAR. It has had the air box removed and a k&n cone air filter fitted. the filter has been fitted inbetween the enging and rad. The problem i am experiencing is with regards to tick over and running it ticks over constant for ages and then sounds like it is grabbing for air at short/longer periods of time, tick over goes up and down. when i push it it gets worse, we went out last night and took it realy steady it was ok until i poked my foot down and it just jerks and backfires. i was wondering if the air cone is in the wrong place where it is and should be put infront of the rad, i was told it should take in cold air?
Answer: I wouldn't blame the air filter position for all that. It sounds like you have a management problem somewhere. They used to be prone to throttle pot and map sensor faults.

Question: hi alan, standard mg metro turbo engine. have a boost gauge plumbed in and also a bleed valve and dump valve.when i first connected it all the dump valve did not work and when i went on boost i had a very lound hissing sound and a loss of power. since then after reading around, i have found that there is a poppet valve inside the plenum. after being told by several people to remove this valve and blank it off. i have now done this and now i no longer have any hiss or loss of power but do have a very high pitched whine when i come on boost and still no \"dump\" from the dump valve. this whine doesnt sound right at all so i only did it twice during my test runs. any idea what it is or how it can be solved.many thanks
Answer: Possible damage to the turbo itself. A broken blade can make a lot of noise. It's hard to tell without hearing the noise of course. Are you sure you plumbed the DV in correctly? If you can't see anything on the outside, you may have to pull it to bits.
