I'm finally going to get the car tuned by john dixon on Saturday. So I thought it might be nice for people to guess what power I will come back with (providing it doesn't go tits up)

 

So a basic run down on the spec that'll probably make a difference...

Forged internals - eagle rods etc etc

Greddy td05 16G turbos

740cc nismo injectors

AMS Underdrive pulley

New splitfire coilpacks

All the usual stuff like air filter and exhaust etc.

Southbend clutch and RPS segmented flywheel

Can't remember all the other basic stuff

 

So come on guess away. Feel free to ask if anything else is done

Goodluck today mate:clover: and hope to see you at JAE:thumbup1:

495?

Come on then, get the figures up.........

537

539

 

Hurry up and tell us all

come on then spill the beans what did it make

Is there a prize? if so Im having another guess...lol....

or the Missus said Ive spent two days in a garage you are taking me out for a meal.... and he is lmao...

 

Text him Mikey and tell him hes a pussy cat... lol...

 

See you at JAE..... finally..... from what Ive read, dont know if thats a good or bad thing... lmao....

hes on line ... ... come on tell us

I heard a rumour its been mapped to a value he can handle.. my new guess is 96... :laugh:

lol. im ok really. but if im pissed keep away. :rofl:

ill be the guy walking around in my onesie at night. i looks sexy. lol

The birds can't keep there hands of me in my onesie....! oops thats my boiler suit.......! to much cidre....!

I know..... But I was there when it was mapped!

I know..... But I was there when it was mapped!

 

Nick, I know yours too.. lol....

 

Hwo are you finding the Jimmer rebuild? Are you at KAE?

Not mate I'm on holiday for JAE. Bit disappointed that something so silly stopped John from mapping it to its potential

are you going to sort and take back for another map? thats still a powerful motor Mate...... Must be happy with the results as well....?

For the reletavely low amount of boost it's running, yeah pretty pleased. Yeah deffo having it re done soon. Just got to hardware a conzult cable into the loom close the the ecu and then start again

Popular tread this one lol.

 

Right. So firstly it's a little disappointing to be honest, it ended up at 452 point something.

 

So that problems I had were:

Believe it or not, the exhaust was too small and resticting. So that was a problem. The mid to rear section is only a 2" pipe.

Next, I need to upgrade the cams.

 

The main one at the minute is the exhaust though. Anyone got any ideas what I should get?

 

When the car went in today it had an fc tuning map and to be honest wasn't running well at all, also the timing was out by either 6 or 9 degrees (can't remember exactly). Was also running something or other which was very dangerous - 14 afr or something like that.

 

Anyway, it's running a lot nicer now and is obviously quicker so that's good but would like liked higher figures.

452bhp is nothing to be disapointed at depending of course at what revs and torque figures you got at the same time? as this will determine the drivability on the road, and how come the timing was out as it had been checked over ? thats poor.

 

Personally I would not change the cams and instead go for adjustable cam pulleys, that way the exhaust valve opening can be delayed slightly which should improve on the generally poor header design, the restriction as you describe in the exhaust is not as bad a problem as the poor header tuning issues.

That torque was quite good, I don't have the printout with me but I'm sure it was over 400. The car drives a lot better.

 

I think one of tHe belts have skipped a tooth mate or the CAS ain't eight as we've had to turn it fully to one side to get the right timing. I can put the printout up tomorrow if you like.

 

Where would I get the adjustable cam pulleys?

 

John was a great help and all round a great guy. Did a lot more than the or opus guys who were looking to tune it.

 

It also wants to cut out after being on boost, revs drop off, the idle control valve was changes but didn't fix it... Did make it better tho

i believe I win whats my price lol

436 do i win a price if im closest lol

 

the proof

thats the joy of the z trial and error I no enough about error that you could right a book on

great thread blw:thumbup1:

I would get the exhaust fixed first, the adjustable cam pulleys will unlock some power, but require an awful lot of tuning time to do it. I would also argue that with stock cams, it's not worth it.

I think one of tHe belts have skipped a tooth

:shock: not possible with a correctly installed belt, how come so many basic set up issues have been left unsorted to then be done at the RR session after been pre-checked?

 

Building engines to big power should involve been set up correctly from the off, this "oh its on a run in map" is a cop out in my view and then to find basic timing issue, boost and tickover stability problems?? take it back to where it was done and demand it is sorted and get your RR money back for the wasted time.

 

Jeff TT

Jeff is quite right, the basics have to be sorted before trying to unlock power, regardless of spec
