Thanks mate, i'll be sure to get the graphs posted up as soon as i have the files emailed over from Charlie...

Sounds like you had a day of it!:(
I'm sure it will be worth it thou! What probs did you have fitting the trumpet as I have got the same one! I'm not copying you:) just seems that we have got a lot of the same parts |

I needed the 76mm - 80mm airbox hose to ensure a good fit on the trumpet! |
Today wasn't a great day to bring closure to the project.
For some reason i wasn't holding boost properly and only achieved just under 1.7bar peak and dropped off to 1.6 post 5k. It pulls really hard but the power tails right off when the boost drops which is probably why it feels mid 400's when it comes on boost and its pulling but the figures were not showing at the top end as it lost boost. Charlie said he can feel it pulling hard on the rollers when the boost comes in and the first run it started jumping the rollers so we had to strap it down harder! Only made 408.6bhp and 390ft/lb, and we know it can do alot more than that. Possibly BCS, possibly MAP sensor, possibly Actuator? Will be investigating to see what can be done. Fueling seemed a bit rich but the Wideband control is on the way so will worry about fuelling after that. Anyway a few pics and a vid of the day as it was... http://i152.photobucket.com/albums/s...1052010673.jpg http://i152.photobucket.com/albums/s...1052010672.jpg http://i152.photobucket.com/albums/s...1052010675.jpg http://i152.photobucket.com/albums/s...1052010676.jpg http://i152.photobucket.com/albums/s...log/Y56vk3.jpg http://i152.photobucket.com/albums/s...log/Y56vk2.jpg http://i152.photobucket.com/albums/s...h_DSCF1029.jpg |
Mate 400bhp atw isnt to be sniffed at. In a classic it will be bolistic. :drive:
|
sounds like actuator or a small boost leak.

Cheers Nige! Yeah agreed tone, something somehwere is misbehaving! hope to pin point it ASAP :fool: |
Boost control drops slightly yes, but it's quite stable so it may be that the duty it set fine for the road but under-achieves on the rollers. if it was a BCS issue I would expect to see more oscillation on the graph.
Does it read the same boost out on the road. If the boost control on the road only just achieves the mapped desidered boost, then on the rollers, where the induced load is slightly less it will under-achieve. Not sure how good the syvecs is on boost control, but the OE ECU has a level of learning i.e if it doesn't achieve target boost it will add or take away a % (within the mapped limits) in order to achieve target. The fuelling also looks OK, you don't want it reading much leaner then that on Charlies rollers, most on his RR read under 11 AFR but read leaner i.e 11.2/11.3 out on the road. TBH looks like a Bob map...nice and safe.... FYI Mine reads bang on 11.2AFR on the road but on charlies the plot was similar to yours. |
Agree with above.
400 in a classic is an achievement and I believe is a great balance for a P1. Chin up you ;) |

Would not agree on looks like bob mapp as his normally a boost junky |

As I say, just my thoughts an I'm more than happy to be proved wrong but hey... :) |
Sorry to hear things didn't go as you quite wanted them mate.
I'm sure it'll all step into line with a little tinkering. Keep the faith mate, you'll get there :yeah: |
At least your cars on road Spooks...
Im sure you will get to the bottom of it.. :-) |
Just got back from Bob's with another successful mapping session
Plan was to play with the wastegate duties and up to boost to nearer 2.0bar and hit 450-460bhp, finish with wideband fuel control install and setup and finish the ALS and LC. But i told bob to leave the WG duties alone as the car is fast enough as it is, and i needed to preserve my gearbox! very hard for me to say as i've very greedy with the figures lol but definately the right choice. The ALS and LC is awesome, i've set them up as below: CAL 1: Normal CAL 2: Normal + ALS CAL 3: Normal + LC CAL 4: Normal + LC + ALS CAL 5: Normal + LC + ALS + 330rpm CAL 6: Normal + LC + ALS + 660rpm CAL 7: Normal + LC + ALS + 990rpm CAL 8: Valet mode 3k rpm limit The ALS really does make a difference to the pulling force through the gears, its very impressive. I umm'd and arr's about whether to launch on the standard box but i soon found myself engaging 1st with the Lc and ALS on and went for it. It was like a rocket! i'm very used to my car and it doesn't give me many suprises but it was really shocked how fast it took off! The LC is so loud too, it sounds like an airstrike! Will got some vids up as soon as i get some more petrol LOL |
I miss updating this so I was trying to find an update… lol
Ah yes! Clutch line split! Decided to go just as I was queuing up to the exhibitors gate at Modified Live this year! Wasn’t impressed :doh: But having seen a recent Bear Grylls documentary I was inspired to fix the problem with what ever I could find… I managed to conjure up 2 zip ties, some double sided tape, some gaffa tape, some insulation tape, a jubilee clip and some sticks and wild berries which I used to make a screwdriver. First double sided tape, then insulation, then gaffa, then jubilee then the zip ties… then a quick pressure adjustment on the jubilee clip to get the pedal feel just right and the job was a good’un! :D http://i152.photobucket.com/albums/s...7062010285.jpg Felt good as new and got me from Brands Hatch to home a few junctions away and then from home to Bristol with no dramas! It made me feel real manly like :lol: Got to Bristol to see Spencer and the gang and had a trick braided version fitted in replacement 8-) http://i152.photobucket.com/albums/s...Clutchline.jpg http://i152.photobucket.com/albums/s...72010349-1.jpg Still saving for gearbox and clutch :getmecoat: |
:lol: Glad you managed to find a fix!
You definately need to do some proper external videos - the car sounded mint when I saw/heard it a few weeks ago! :doubleup: |
Cheers mate! I do indeed. Mate has a go pro (not sure if i told you about that that night?) so were messing round with that at the mo! will have one sometime this year lol

Oh yes lol had it on the corner of my bonnet, then proceeded to film the police car infront for the next 5 minutes lol

Give us a shout if you want another set of hands for filming - I'll quite happily spend a few hours watching launches! |
Wicked will do :five:
