It doesn't go all the way trhough because we were in the process of putting more timing in so wasn't doing full 0-limiter runs as like i said we were in a rush, shortly after the clutch started to slip so we called it a day. Gaz did me that map in approximately 30 minutes as I needed to take the car out and bed the brakes in so i was rushing him. This graph was never meant to be a propper power run but you wanted evidence so i got it for you.
I don't know why it's that shape and i don't know what shape you think it should be but that's just how it is. I don't fully understand mapping so can't answer, I don't see why it matters though that proves how smooth the power comes in.
Sorry mate but all you've done is tried to call me a liar after i proved you wrong. It's not on and I'm sure if Gaz saw this he wouldn't be happy that your calling him a liar as well as he prides himself on his honesty with customers!

so basically you are agreeing with what i am saying the graph is not an accurate represention of what you have and the figures cannot be taken as fact -- that fine then

Because we didn't rev it all the way through?
I said you can build a 200bhp+ turbo saxo for less than a supercharger would cost and if set up right the power won't suddenly come in after loads of lag and kill everything.
You asked for a graph.
I've given you one that proves exactly that, and because he let off 500rpm before my limiter I am a liar? Like i said didn't want to get into this arguement just wanted to put some evidence in as you were flooding it with supercharger hype. Now I've given you evidence your ignoring it and talking shit. Nice work.

so john...while we're on the subject, the graphs i posted previousley, would you say they look "ok" other then the apparant richness up top?
ive not really had any feadback on them at all, the car certainley drives well, has god spread of useable power through the box, and tails off about where it should for the turbo im using, looking at graphs i can see from mapped s13's running the same turbo, it seems to follow pretty much the same lines as those.....

Just ignore john peeps! he's just a narrow minded person who thinks all turbos are terrible with lag and will destroy driveshafts! From a business point of view your just turning customers away with your attitude!

tbh that's what i was thinking, his attitude has definately put me off of dealing with GMC
In fact looking back at my graph could be just how the printer is set up, to show it only to peak BHP, which would be exactly what it shows, dont know will have to check with Gaz. Like i said though wasn't a power run this was just one of many runs we did doing the quick map for Trax.

His attitude put me off dealing with him quite a while ago, a few guys say a few cheeky things locally "Hi, im John and i'll charge you ££ just to talk to me" so you guys should be grateful off getting information on the forum for free. After many of my mates used them locally in the last few years, that has also put me off GMC, one of my mates starlets running 300+ bhp went in for a RR there, john decided before it went on that "no way in hell, will this sort of car, make that sort of power" little does he know, the 1.3 has broke 500 bhp now., anyways, chris came out with a graph of 260- or something around that. went up to another RR in glasgow and made 318 i believe within 3 days, no changes made.
here is johns graphs,
TD05 16g, doesnt really come into its own till just 5k rpm, and powers all past revline, but imho you can see from the graph, john eased off at 6400, the car rev limit was mapped at 7500. i know, as i had a car more or less the same spec, and this car had a bit more headwork, same mapper, mine made 327.
you can see a few power dips, but can clearly see he's let of the throttle and not used the rev range on the dyno.
this is only one of the poor dealings i know about.
there is another, recently with a charged saxo that went back to him, with after being worked on, needed some wheel nuts retightened 10 mins after leaving gmc.

exact same with me, hard to get a straight answer and awkward to talk too when all you are doing is trying to ask a question about something when you where going to be giving him 2k+ of business

Everyone's allowed opinions etc but I would hate to see this turn into a anti GMC thread..
Let's talk about the topic in hand. Boost+bodies
I'm sure it says in the bible turbos are better than superchargers anyway ???

I was brought up being told a turbo was better. didnt need a reason why, its just Gospel. and all the engines i work on are turbo'd. so must be true.

surely a supercharger and turbo should be combined.

I have been seriously considering this.. Twincharging has had some very interested and impressive results.
The reason I discarded the idea is my external wastegate would be in the way.

i have been, i think it would be possible with the positioning of the turbo using the miltek manifold from cituining.
not sure how difficult it would be mapping it tho

What are the ball bearing turbos like to aid spool up time are they any better than the journal and thrust bearings turbos.
