cheers mate... once again darren u r rite. the track wil decide it all...

The car wasn't detuned for the dyno day it should have gone 330 as it was tuned. It runs 33% toluene/premium mix. As im sure you people would have seen the dyno graphs that were posted (my web hosing is down to host i might put on a public hosting site) that there was definatly something happeneing at boost worx (wavy up top) weather it be wheel spin/something ****ing up no one can be sure. I have probably done over 20+ full power pulls and never had any graph come out looking like that. Draw your own conclusions. The car was brought back to hitechs few weeks later and pulled within a few kw of its previous reading, and has since had 2 more psi added now reading 350 rwkw. At the end of the day i would rather goto the drags and run quick times, but this will have to wait witht he current situation at AIR. Closest thing i have found to race is a R1 with full exhaust and power commander - even so seems good enough for me. For hitech reading high, that VL turbo with 330 rwkw went 10.5 at what 130 mph?? Seems to add up to me... There are the 2 sheets, i drew some common points on both graphs, as you can see the dynos are with in what 8 kw or so (acording to my 2am eyes ), then at the top it goes a bit ****ed up, if my dyno was so called 'reading high with corrections' or what ever is going on wouldnt it be higher everywhere? Some original photos have not been recovered yet.

May have something to do with the shootout mode ran... As we saw with Chops's LS1. The lower the shootout mode the lower the power reading. I believe the difference between his was something like 30-40rwkw. I forget exactly.

I fail to see how shoot out mode is effecting only some points on the dyno print out where where up to about 130 kph boost worx is actually reading higher, then takes a massive dip. If that was the case i would be expecting to see the reduction, or at least a percentage reduction over the whole graph. i have a print out here of 350 rwkw, in shoot out 4F, 24 psi, 3rd gear... i dont have one of a 330 rwkw run with the 'shoot out mode' box attached to it, only 350.

Who cares... it didn't make the power on the day. :P its just bad luck really... maybe the ramp rate played funny buggers with something.. it really should have been in shoot4f not shoot4.

Im not overly bothered, I only seen this thread because my friend told me about it, and the argument of hitech reading high is still going on, which in my opinion is a load of ****. If i had a lap top connected to the autronic with it data logging on the day i might have been able to see the problem, or maby even if the dyno was also logging boost etc because on the day something definatly happened to effect the top part of that curve.

So in saying that it was an error on the dyno operators behalf? Anyway, like Cubes said it didnt make it on the day but with all the killa shit on that SR and a 1.06 GT35/40 it seems only logical that it would make around the figures it has made on Johns dyno.

The only little gripe I had was how you slapped crap up on your web site that looked like an attempt to question Shauns credability. You should have taken it on the chin, it obviously had somthing funky going on as a 45rwkw is quite a difference, a difference that is too large to be dyno related especially when others cars are jumping on the dyno making more power than what yours where. MS75 391rwkw is a prime example. if something was up with the dyno it would have most definitely showed.. He received the power output he expected that was similiar to that of the blackwood dyno that he tunes on. When mines on the dyno next I might see if shauns still got your power run, I'll have a look at the boost and afr out of my own curiosity. If I see something strange I'll drop u a pm as I'm sure you are perplexed as to what went on. Wyndup, Not really an error... He may have had his reasons for running it in the n/a mode. I have noticed in the past Shaun has run mine up in the SHOOT6 N/a mode (Shoot6F is forced induction 6cyl) I'm not 100% sure on the differences but I do believe the greater the shoot out mode the softer the ramp rate is to prevent wheel spin.. I.e shoot8f with a v8's forced induction massive mid range is likely to have traction issues compared to a 6cyl turbo. Maybe its shauns way of loading the car up that little bit more to get it spooling earlier, induce any possible detonation that may only be seen when loading the car up in 5th gear or something. I'm really not 100% sure. I'm sure JetR31 is more than capable of tying down cars to prevent wheelspin, he had no issues with MS75 and sky30's, + he was sitting by the back wheels so he would have seen if it began to slip.

Only reason I was pissed on the day was shaun goes 'john must be using a high ramp rate to get the numbers' I mean whats with that. He didnt look at it and so oh looks like something isnt working correctly be it you boost controller/ebc/something it was just that straight out. I went back to john and we put the car on the dyno again and checked this exact thing, we used Shoot out 4F with its ramp rate of 150, then non shoot out mode with 150 rr, then non shoot out with ramp rate 100 all reading with in around 5 kw of each other. If you have a look that will be good, but i dont actually think boost was logged, not to sure about AFRs. edit about ramp rates, 4 runs a rr of 100 where 4F runs rr of 150, in my understanding 150 lets the rollers accelerate more freely so there is less chance of wheel spin.

Its a silly question but was it up to operating temp? May have still been running the water temp ign and fuel correction values.

Thought it was something like that.

Not sure but you could well be correct. wasnt running for all that long. if it went rich or pulled timing could make the top end all funny, plausable explanation.

Dyno days are pretty bodgy/dangerous when you consider the cars aren't really up to operating temp.. :S

i think we need to organise some street dyno sessions* lol *i do not condone street racing Some original photos have not been recovered yet.

The engine bay is killer, but yeah, that day it looked flat on the rollers, not what i expected, i expected it to be like my car and mS-75, where they try to leap off and get up on the rollers, a sign of a strong torque curve. But like i said whatever happened on the day happened , blacktop dynos rock , be good when we all get a track cheers darren Some original photos have not been recovered yet.

it did make 500 foot pound at AED engine dyno, whats that nearly 700 Nm, the land cruise motor probably makes close to if not over 1000 Nm (guess)

I've got a majority of the dyno sheets from the dyno day. Some original photos have not been recovered yet.

but is that accurate, my figure is from an actual engine dyno, to get that you would have to enter exact tyre diameters etc?

lol.. nar its a rolling road figure all altered by tyre and gearing as you know :P Interesting to see how far out it is from the real figure though.. I'd say Seans is up around 1000nm maybe a touch more considering the rev's it uses to make the power it does. Which is pretty insane from a stock donk. :P
