The Map was aborted as the injectors reached 95% duty.
So it was curtailed until new injectors are fitted.
As for fuel pressure what ever the walbro competition fuel pump can produce.

Thanks for the comments. I am going to wait for the new injectors and FMIC or charge cooler to be fitted before I go looking for a decent RR I have heard that prosports at Stockport are excellent.

T-uk and I saw this power graph or one very much like it posted somewhere else last night and both thought the same about the top end, if not the same car, it was the same rollers and had the same kink at the top. I also put forward my reservations about Tweenierob's curve from PE on a 20G previously in his thread about the top end (he had about 15 BHP more than me, I had too ), but on that plot you could see if from other data given IIRC. Nice result, but the bit at the top is an obvious aberration until proven otherwise IMHO.
Someone else produced about 380 BHP out of a VF28 on a classic car with just a remap and exhaust, and I didn't believe that either.
However, it is always easy to diss other people's dyno results
FWIW, I don't believe the VF34 is a 400 BHP turbo on a 2.0 Subaru running pump fuel either, neither is the TD05, MD304 or whatever. Not on a dyno I could believe anyway. The iON P450 is but we've already had that discussion

Having just looked at all the Well Lane graphs on dyno.scoobynet.co.uk about 50% display humps at the top end of one sort or another, especially once you get over about 280hp.
Perhaps you are right John about Rob's graph with the 20g, infact I found a copy of the scan on my puter the other night, and thought the same! At the time it was blamed on slip, which doesn't make sense, but having seen the oddities in the coastdown part of the dynorun, it makes much more sense.

Lol, now that it is not my highest figure i can possibly believe it to be inaccurate john
I understand it as the car spinning the rollers on lift off as the car hits the rev limiter, this surge when the rollers are calculating the losses 'may' give increased losses...
which is why the more weight you have in/on the car the less chance of it surging when it hits the limiter? sound credible?

Hi John,
That was my post you read last night it was either on the RB5 oc or the AMG 55 debate
Had to create a new ID today at work as I couldnt remember my password.
AKA DazDavies
Thanks for your constructive comments mate I too thought the RR figure was a Tad high. None the less I am pleased with the actuall power I have out on the road

Just remapped Alan Bells car today after it was fitted with a bigger MAF sensor (the 20G had maxed out the std one) , I took special note of the spool point on the turbo,
From 2000 rpm in top, 0.5 bar at 2830rpm, 1bar at 3132rpm and 1.5 bar from 3355 rpm.
No surge whatsoever, no doubt Steven will be able to verify this when he has a run in it at some point
Datalog available if req'd !

Having chatted at length with Andy on the phone, he explained a few differences with the latest 20g units he has sold. We would normal consider these changes a retrograde step, but so far they seem to hold back the surge to an acceptable level. If that's true, then I would say there are fewer reasons to not buy a 20g.
The worst one of all though was Andy's old RA, biggest surge monster ever seen!

Yes that was bad Paul I learned a lot from that car, most of all was to be prepared to throw in the bin a new shiney custom made bit that has taken hours of work to make Tip for today, never fit a 4" inlet pipe to a 20G

5th would be similar to 6th, they don't really accelerate that hard at that rpm in 5/6th.
From memory in 4th it was 1.5 bar at 3500rpm. An AVC-R may be able to improve on this as it eliminates wastegate creep better than a Dawes/GBE valve.
IIRC the 6th gear on Alans car is the same as a UK 5th. Assuming its a UK 6sp not a JDM ?

out of the IHI webpage:
just in case someone needs help .....
just in case someone needs help .....
The amount of air entering the turbo is usually measured in cubic meters per second (m3/s), in pounds per minute (lb/min), or in kilograms per second (kg/s). I personally like the m3/s that Mitsubishi Heavy Industries (MHI) uses on most of their compressor flow maps because there is no ambiguity in converting to cubic feet per minute (cfm) a rate more familiar to American hotrodders. Multiply every 0.10 m3/s by 211.8882 to get cfm.

Very interesting thread this - I'm sure it will run on for a lot longer too.
A quick question please to those in the know.
My P1 is Tek3'd (thanks to Bob ) and with decat and Green panel filter, it recently ran 307bhp at PE. I plan to do future mods in 3 stages - can anyone give a rough idea of what to expect after each stage: -
Stage 1 - Sti8 I/C scoop, STi8 I/C and Waterspray + remap
Stage 2 - Full 3" turbo-back system (poss from RCM), Modified inlet to remove standard airbox - maybe use cold air inlet, etc (any suggestions) + remap
Stage 3 - New Turbo - TD05/06-20G + remap
I'm not sure if I would need larger injectors also by the time I get to the turbo mod (probably 12 months away - but comments welcome) - I already have uprated fuel pump.
I dare say that a lot of people are in a similar state of tune to mine - decat, filter + remap and I'm sure they will be interested to know what the different stages as described above could produce.
Many thanks in advance.
Terry

aaaaand it was done at 1.5bar ..... personally I think the car should be VERY nice to drive. And with proper race gas >350hp is possible (pushing the rpm limit of the turbo by using a stronger WG actuator) but 400hp come on !!!!! if they got 400hp out of that turbo either they are not using a four stroke engine, or there was some sort of error with the rolling dyno or the guy that got 400hp out of a VF34 should be hired by Minardi so that they can keep up with the Ferraris !

If a 20g can wash out the stock MAF, what is the 'upgrade'?
What happened to Andy and (I think) John Banks' MAF substitute for the Apexi FC?
This is the first note about a MAF sensor maxing out.
Are there any more surprises out there?
