Let's play guess the Bhp

Yes the Apexi pfc (which you have) has an option to add or remove fuel below or above a certain temperature which i can adjust when i map her Tuesday. Many dont alter these settings which is why so many cars have issues starting when turned off hot (say whilst refuelling) then if they dont start straight away they flood, same goes for overfuelling below a certain temperature!

Trouble is that if im honest it is a bit of guesswork as the car is hot when you map it so unless you have it for hours after to see how it starts & runs on a cold day you can only guess the fuel % to add or remove

But at least we know what your car does Rob so il pull some fuel out of the whole map with temps below say 30 degrees fahrenheit.

Smell the oil night before you leave and if it smells strongly of fuel just chuck some cheap oil in it and we will change it for the good stuff just before it goes on dyno.

One thing it does do .  Is If I start it up and don't let it get hot and turn it off   it struggles to restart ..  


For example  start it up drove it out of my garage and then turn off  it will struggle to restart   ..

Same even if you leaving it idle for 10 mins

Only way I'll get it started is pull plugs out and dry them out and put them back in

How ever do the same but let it get hot hot  ( 30 mins  on idle )
Then turn off it will start first flick


If you start it then drive it round for 5 mins   it will restart

You may possibly have a dodgy ecu temp sensor dont worry will check it all out Tuesday before its on dyno

Last chance to get bets on the bhp .
Tomorrow is dyno day

394.3

374.26

360 for me with those injectors. Great if you get more

I don't think you could of pick any closer then me

He had the option for bigger ones on the day if needed I think

How did you get on rob ???

good 555cc and good pump and decent AFPR should do cope with around 400hp and still be in in 80 to 90% duty, Lots of other things could hinder the final figure, hope was good day for all involved ...

We are still here ..   lol   ...   so far   290.9 @ 0.6 bar

Been a long day .

I will say one thing for Bob   .
He's bloody methodical

That's dedication for you .

Still here 353 @ 1 bar .. Lots more to come

397.9 @1.45 still a lot more if needed . I'm starting to shit myself tho

you not even driven it yet lol . sure bob got a toilet you can use lol .
You stuck with 555cc or gone bigger .

401bhp
397lbft torque 1.5 tailing off to 1.35  boost controller duty needs upping but too fookin knackered to do any more

I reckon i could have got 420 out of this which is excellent for an old 2871r
Full credit to Rob for assembling it so well, very very good car everything put together properly  


Looks like Mystic John is spot on again lol
Can you believe that, he also won around £50 on our dyno day
Dont need a dyno to assess bhp just ask John

Just got home 25hrs after leaving the island ..

What can I say that hasn't already been said by someone before  .
Bob went above and beyond as usual  ..  car drives lovely and pulls like a train .  

I'll write abit more tomoz   but right now I'm off to bed .
Gotta be up in 4hrs

That's good going!! Could you put a graph up rob? Would like to see how quick it spools up etc, may be able to find one of my old graphs with it on and compare them. Made more than I could get out of it

Thats awesome, great to hear guys!

good result mate!

Nice one...

Ignore the afr's the sensor was playing up .

Is this wheel or flywheel?

Flywheel
