My old 1999 me7 v70 with 19T, 3" downpipe, Milltek cat back and Rica stage 2 map used to do 7 secs with a full interior and 2 occupants.

is that a P2? if it is, it's hard to compare as they do over 100mph in third so don't need any gearchanges.

It was a P1 irf.

What sort of time should you be expecting from your car Bonelorry? It was blatantly the Rica that made your previous car so quick

[jardon]

Is 8 seconds bad if it includes a gear change and uphill? Up a slight incline I was getting half a second longer. Ignore P2 figures but with a 2nd and 3rd gear run
I was getting about 6.5 seconds - chuck in a change to 4th and I'd be up around 8. Do some runs on a flat road and perfect your gearchange before judging the result too harshly.

I would probably expect a 7 second run, My first run was slightly uphill but my 2nd was on a flat section of straight road and had i have held 3rd gear for longer i wreckon i could have broken into the 7 second mark with that run.

Ive always suspected the car was never really as quick as it should be, Im not going down the Rica/MTE debate but i will say one thing. I live in a very hilly part of yorkshire and my journey to work consists of some seriously long lowish speed hills, All my Rica'd cars had a big whack down the bottom end of the rev range but nothing up top and the MTE map is the opposite very little below 3500rpm then its all up the top.

My old S70R with Rica 310 and no other mods was a faster car point to point on my route to work than my current more extensivly modififed MTE mapped 850R because it was far more drivable low down the rev range, Once i get onto a straight and flat bit of road the MTE map wins everytime becuase it just keeps on pulling upto the redline.

I drove tonyt-5's car yesterday which currently has a Rica ecu fitted and below 3000rpm even with 3 people in his car and full interior his car was so responsive and made minced meat out of the hill i struggle to get up everyday in my fully stripped car, Im not talking about WOT either im talking part throttle.

Im going to be doing a boost leak test just for piece of mind soon and fingers crossed i find something.

No your totally right, My gearchanges arnt exactly the quickest having just fitted a quickshift plate im still getting used to it.

8 seconds is more acceptable and if you look at my 2nd run its a similar time with 2 gearchanges!

4th gear 80-120mph (started at just over 70) 7.7secs - stopwatch and speedo. Flat road, half tank, 18C and just me in the car. Still stock intercooler.

Methanol injection is the key in my car - I have been adjusting trigger pressures to see what happens and I can run my 0.7mm jet from 0.1 bar with no hesitation and in fact it feels more spritely than triggering at 1.0 bar. With water only it would bog horribly with a 0.7mm jet activated at 0.7 bar.

It will still run a 5.5-5.7 sec 60-100 in 3rd too at 20C ambient so not too much power loss with higher temps (was 5.2-5.3secs 3C). I did try running smaller jets a while ago when it was hesitating on water but it's all about the methanol in my application.

Sorry about the multiple postings in this thread but it's been a learning curve for me and I like to share.

It's official, I can see the headlines now.

I've just downloaded aDyno for Android, I shall have a go and then report back- quite interested to see what it does.

[irf]

erm. how is that relevant in any way to this thread tony?

i think your stop watch is running fast lol

im sure below 6 seconds is garrett terratory my car doesnt get close to that

I datalogged 9 runs a few nights ago with softloader and the average was 5.6 seconds. Even uphill it's sub 6. I'll video a few and post them up - it isn't the first ME7 car with MTE software and a TD04 turbo to run comfortably sub 6. Now running a 1mm Aquamist jet and neat meth - it's a totally different car without meth. On the day of tuning Marco added 3-6 degrees of advance while running meth and straight away my clutch gave in. It is running a surprising amount of advance with no knock sensor intervention on meth. Garrett territory is 4-4.5secs in my limited experience.

[irf]

don't worry shem your cars the quickest 850 eva!

i know turkish was claiming 6-6.5 seconds for his 60-100 with the blue estate he had (it might even be in this thread, dunno) and when we went side by side your car was clearly quicker which he had no problem admitting to(again, on the forum somewhere). so in summary, P2's suck balls

jardon, just to be clear i don't doubt your figures for a second, you're too bloody methodical!!

[jardon]

I never want to overplay what my car will do hence the numerous contibutions to this thread. I can't believe it's that quick either hence measuring it time and time again - with different stopwatches and datalogging, in winter and summer, with and without methanol. I will post video though -just to defend my P2 honour!

[irf]

video would be good for pure entertainment but like i said i don't doubt your figures for a second

[jardon]

Thanks mate - want to get one of those Beltronics road dyno things too. I think they are quite cheap compared to the VBox ones and Dooby got some good (accurate) results. I'd like some method of plotting a torque curve that I can use to evaluate effect of methanol and addition of new intercooler, etc.

Pay no attention to Irf Huw, he's just jealous that he will only achieve those sorts of times if his car is towed by yours......

Just kidding Irf....love you really!!

With a Garrett -71 you can do around 4
