Sam Mcgoo Posted May 10, 2011 Posted May 10, 2011 Well, following on from this thread - viewtopic.php?f=114&t=44722 I decided that I would carry out a few mods to my Supercharger set up, mainly for safety/longevity reasons but also to improve drive-ability and maybe gain a couple of horses while I'm at it. Previous spec -54 UK GT with the following engine mods; Vortech V2 S/C Kit 3.33" pulley Autosportwiring ECU harness Split-second timing ECU piggyback Kinetix SSV Inlet Manifold Invidia true dual exhaust Kinetix HF Cats Denso Iridium one-step colder plugs JWT Oil pan spacer Pneumatic engine damper So I have now removed the Autosport wiring harness, Split Second Timing Piggyback, Vortech FMU, inline fuel pump and Kinetix HFC. I've fitted a Walboro 255 fuel pump with modded carrier, AAM Return fuel system and Japspeed test pipes/decats. I left the car with Abbey and they have fitted DW600cc injectors. Mark made a start on it last week but max'd out the MAF sensor while tuning....so it now has a PMAS fitted also. So........I should get some results in the next day or so when Mark finishes it off. I feel like a kid at Christmas. Previously the car made 369.1 hp at the hubs circa 400FWhp and 325 Ibft OLD PLOT So for a bit of fun anyone fancy a guess at what the new results will be? Not expecting a big increase - so my guess is 375hp @hubs and 335 Ibft Quote
nurrish Posted May 10, 2011 Posted May 10, 2011 Maxed out your maf sensor...i was running 460 fwhp using the standard maf sensor..and mark said these numbers wouldnt max out the maf sensor ...I dont think your far off with your guess Quote
Ian Posted May 10, 2011 Posted May 10, 2011 Maxed out your maf sensor...i was running 460 fwhp using the standard maf sensor..and mark said these numbers wouldnt max out the maf sensor ...I dont think your far off with your guess Mine was maxed at 420 fly. Quote
nurrish Posted May 10, 2011 Posted May 10, 2011 So why did mine keep going then i have dynos hitting 500 fwhp! Quote
Sam Mcgoo Posted May 10, 2011 Author Posted May 10, 2011 As Ian said, every car will be a bit different. At a guess, I would say that it was more about total flow through the intake, engine and exhaust rather than power. Nurrish- I can't remember what your inlet / exhaust set up was. Maybe with the SSV, decat and true dual exhaust mine is flowing more than yours was? I remember you had the 2.87 pulley so your high power would have been through the increased boost. Ian had a Cosworth plenum so maybe the improved plenums are the reason for the extra flow? Mark said my MAF topped out at 5.04v at 6000 rpm so power and torque took a plunge from there. Quote
nurrish Posted May 10, 2011 Posted May 10, 2011 I just had standard plenum with a k1 exhaust when tuned...it was the 2.87 pulley that gave me all the power...the free flowing it is the less boost is achieved...so what i believe anyway. My car just wanted to keep making power Quote

My car just wanted to keep making power Yeah, your right about the flow/boost relationship. I must admit I was tempted by the 3.12 pulley for a bit extra, but thought better of it. For now. Quote
Tarmac@TarmacSportz Posted May 10, 2011 Posted May 10, 2011 Are you going to Wales Sam ? I know someone 'as well as me' that wants to see your car Quote
andlid Posted May 10, 2011 Posted May 10, 2011 what fuel system exactly did you go for? I'm guessing 430 on the fly Will sound amaaaaaazing, great to hear you dumped the other stuff in favour of the Uprev, will be interesting to compare the plots Quote
Sam Mcgoo Posted May 10, 2011 Author Posted May 10, 2011 Are you going to Wales Sam ? I know someone 'as well as me' that wants to see your car I wasn't planning on it, but it would be nice to go for a run on some proper roads and meet a few of ya. I'll have a word with the missus when I get home at the end of the week. I might be able to swing 1 night/day. She doesn't mind a drive out and I know she'll love the scenery, food and drink, but a weekend of just cars isn't her thing. Quote
