Hi,
printer thawed out at last, Graph of SC42 Billet cracking 500 BHP .:thumb: http://i694.photobucket.com/albums/v...linic/glen.jpg Great result for all, turbo, mapper (JGM) and Glen, have you broke the gearbox yet. :D cheers Kev Gearbox is holding out so far as i havnt gone above 1bar boost,tbh im just enjoying the noises it makes and the way it spools to 1bar,makes me smile every time.:D:thumb: |

Glad to see the printer came back to life Kev,i will get some graphs off you for my collection on saturday when i come up for a cuppa and a chin wag.:thumb:

Torque seems a little lazy down low, do you have bigger cams? Do you have a build thread or car journal? |

Just had my 46/2.5 combo mapped and at 1.65 bar it made 467hp and a tad over 500lbs ft.
Very very happy with that. On 20% meths |

hi kev pm me a price for a sc36 please cash cheers rob
Hi, no need to PM, prices are all on here somewhere, will update them and post them up again to save trawling the thread. :thumb: SC36 billets are £750.00 and come with up and down pipe gaskets. :D All prices + vat cheers Kev |

It's been Dyno mapped so you can knock 1K RPM off of the graph on road, So peak torque by 3700(ish)?
I would quite happliy have 500 horses and 440LB/FT by 3700 RPM anyday. Dyno Dynamics (assuming that the run has been done correctly) show circa 300rpm difference (read - later) against logged boost on the road for my car. |

Not sure what the actual rpm differences are fellas but i can honestly say that it spools ridiculously quick and is a complete animal on the road,on boost driving in the wet is out of the question.:eek::lol1::thumb:

Come on Shaun, you of all people should know you can't put a figure like 300rpm on the difference between Dyno and road. I'm sure it can fluctuate a far bit
Using a Dyno Dynamics RR that has been set-up and car ran correctly (heat in the pipework / turbo) and appropriate airflow, it is around 300rpm difference (between dyno and road) on my car (in the same gear) with similar environment temps / conditions. MAHA spool rates are even closer based on what I have tested. You do realise how many RR's I have been on and much data I have. :) |

The discussion here is that it has been inferred that your peak torque will be 1k rpm earlier on the road, which I will run down the local High Street with my knob hanging out if it was, in 3rd gear. :D |

You do realise how many RR's I have been on and much data I have. :) I'm also not arguing the fact your car might spool 300rpm earlier on road than on dyno, what i was debating is that you can't put a figure you've discovered on yours in comparison with someone elses. Not that i'm saying Glenn's will produce boost 1k earlier but you never know. My first dyno run over 3 years ago was on a standard MY03 sti and was a Dyno Dynamics RR. Dyno and graph showed full boost at circa 4.2k rpm, whereas on road it was more like 3.4k rpm. :) This aside, Glenn's car is an awesome road car and i for one wouldn't mind owning ;) |

kev
what would the spool be like on your sc 20g on a 2 litre with rcm spec headers plus would u chance it on a standard sti internals on a v3 type r? Also how much is that turbo? cheers rob |

SC 38 Billet £895.00 SC 40 Billet £950.00 All prices + vat. :cry: The earlier discussion about the spool difference on the dyno compared to the road is incorrect, we have seen anything between 400 RPM and 1200 RPM increase in spool on the road compared to the dyno and trust me having owned a Dyno Dynamics rolling road for well over 7 years we have seen a lot of cars, log shows 36,000 runs, we have worn out the rear rollers for a 2nd time, new ones being installed over Xmas. :D A new turbo we were testing Friday last week made full boost at 4500 RPM on the dyno yet made it at 3500 RPM on the road, tested in 4th on a six speeder, interestingly on the road in 6th gear it spooled 1500 RPM quicker than it did in 4th on the dyno. :) I would imagine Martyn at engine tuner has found the same, and I guess his dyno has done more runs than ours seeing as they also tune other cars. :thumb: I wonder what Charlie at Surrey rolling road finds as his dyno never stops. cheers Kev |

Kev,
I really can't understand how this can happen if what I stated as the "caveat's" were taken onboard. I have never seen those kinds of differences on MAHA, Dastek or Dyno Dynamics RR's... between what I have seen on the dyno and what I have seen on the road (for the same gear and environment conditions) - logged. From what I have seen with my own cars, I would have to disagree with you 100% I'm afraid. Not that you'll give a sh1t about that though! :D :lol1: |

Shaun
I've seen significant differences in spool between dyno and road on my car on both an SC46 billet and on a GT30 billet. And trust me when I say that I give even less of a sh1t than Kev does if that goes against your "findings". :D |

Shaun, as nothing but an enthusiastic amateur at best, lol, what would you profess to know about a DD dyno.

Martyn that's a few runs, just re checked ours and its more than I thought at 40,315 runs covering 35,783 Kms, over 22,000 miles. :thumb: We are catching you up Martyn. ;) Cheers Kev |
Lol, I've certainly covered more miles on it than off in the last 6 years having done over 25,000 miles.

Cat fight me thinks:rolleyes:

Kev,
Behave... I said based on what I have seen on my car I would disagree with you. Am I not allowed to disagree with you, even if I have seen with my own eyes contrary information. Martyn, As nothing but a professional at best, why don't you explain to me how I have never seen this on my own cars and what causes it. I was only on Charlies RR a few weeks back and it was 300rpm behind road logged spool. Whilst I FULLY understand it can happen, based on what I was stating as the caveats.... I really don't understand how it does happen. So instead of trying to wave you penis with how many miles you have driven on a set of rollers in your lifetime (I hope I never get stuck in a lift with you) ;) , perhaps you could explain to me the error of my ways and how this happens. Since you live your life on a DD RR that should be no problem for you. :) |

If you are going to profess to be vastly more experienced of something than someone else, quantifying it generally helps :D As you only have experience of your own set ups Shaun, I don't see how you can think to know more about cars or turbos which you have neither driven or own ?
