I've had quite a good result after some minor issues I've had
Think the dip is traction issues

Have you tried doing the power run in 3rd gear instead?

It's the speed your doing in 3rd gear

Yeah, was a recommendation because of the dip thing. Or back to the RR.

Yep I am planning to go back on RR after my next track day The car has never been stronger than it is now and so smooth right through I have also decided to try and challenge the holy grail 400 hp Not that I need it for the car on track But the HArrop could be coming off the car soon back to M62 but before I do, I think it could be possible at least for one run on a RR

On an 80mm? Awsome.

it is at the moment but will be dropping it it to TRY and top 400 hp 

 

possibly 2.8" (71mm)

Do you have E85 available there? If so; throw that in with a smaller puley and yank on the ignition => 400+.

(You probably need bigger injectors for that, but you can get away with a 50/50 petrol/E85 mix, as above 45-50% the Ethanol is not doing much extra anymore.)

Only if you buy it buy the drum at about 4x the price of normal premium pump fuel. No garages sell it in the UK anymore as it was pointless.

[NickB787]

wel done, be interested to see the ign tables that your using If you want to try a smaller pulley I have a couple here, got a 2.8 and 2.9 and maybe a 2.7 laying around

[CHILL Gone DUTCH]

Cheers for the offer nick
I have a 2.9 and a 2.8 pulley here



I'm hoping to be able to reach the target on pump fuel but we will have to see

The ignition I'm using Nick is between 19 and 22.5 under WOT there is a small area where it drops below 19
I'm expecting this to change with more boost due to extra heat produced

Haggi got his 400 on a 2.9 iirc.

Haggi got his 400 on a 2.9 iirc.  

Haggie had the wrong wheel diameter for his gearbox ( close ratio ) at the time but after see Haggies map and ignition settings and power runs I'm sure his will easily reach 400 as his car seems to be somthing very special in the form of IAT Seems to flow better than most engines

[smiley]

Only other breaking 400 i know was a German called Pepi using a 2.75

With your obdtuner skills i am trusting you can do it with a 2.9/2.8

 

 

 

[ufods]

Where do you buy your pulleys from?

[CHILL Gone DUTCH]

smooth flow pulleys in the states

Thats why i mentioned that i want to reach the target with 1 Run on a RR as im in no doubt that the power will drop off without any fancy fuels like WI or E85 

 

i actually think its nothing to do with skill and more to do with time and managing the temps 

 

the hours ive put in to the current map are adding up again 

nobody in there right mind would put the time in that i seem to

That's because it is not really clear how much wiggle room there is between a basemap and your optimised one.

NO ONE has pulled so much out of the 80mm as you have, which paves the road of what can be done, besides chucking on silly pullies.

It's very difficult to pick out what is false knock from road and bangs and what is engine ping/ knock As the knock sensor basically pics it all up What is very good if your in doubt and I'm now using more and more is after adding ignition and optimising it I go and do a full fuel learn session and tick the knock box on the table and see what is being picked up more often as it can be a little temperamental in the power runs Also to watch out for if the Ecu does pick up knock when you process the measurement it pulls that area of ignition extremely low which then you have build it back up again I have found very little knock being picked up in these sessions compared with the power runs and using this has gave me a lot more confidence with in adding the ignition It's also worth saying o think adding ignition in areas is a waste of time as power is not increased And this is why my ignition runs in waves rather than linear I've spoke briefly to frank about this as his runs very linear compared to mine but I have concentrated almost a figure at a time in the ignition tables which is very time consuming It quite interesting that the knock that I do pick up in the learn sessions is from areas with relativity low ignition to start with 15-17 degrees So I think these setting are far to low especially for my engine

The reason Haggis flows well is because of the additional porting. Vocky only did a mild port of the exhaust side on your Saab head. With additional porting of both the inlet and exhaust it would flow much better.
