surely you would need to be pushing 2 bar plus to get 450bhp?1.5 bar would give you high 300's i would of thought!if you had 2.5 litre engine or bigger then it would be possible
lol it's about time i got something right! turbo on picking car up friday then got to do a few hundred miles to bed new pistons/rings in.once mapped i'll pm you mate
PS had to have a new helix clutch as the old one was down to the rivets
550's are gonna be pretty maxed at 450 as well, wouldnt 630's be better?
Or are you running 550 @ 4bar?
Hope it all turns out alright.

I was running 630cc injectors @ 3bar until today morning when I realised it should be at 4bar
JBS do a jbs30 conversion and use the gt3071r, orig map sensor, 550cc injectors etc etc and it makes 450hp so I assumed it was at 1.5bar... mind u that is with a true 1.9block, i dont think mine is!

And plus the effiency range is 1.5bar where it flows most so i thought that would be where it makes most power.. im no expert!
I got a full 3" mandrel system and now the car holds 1bar with boost controller off but with the 2.5" system after 3" D/P it holded 0.9bar, suprised how much better it feels and runs!
Well 20th october is my make or break day! I have everything sortd this time for a proper remapping session, and using the TDI 3bar map sensor so I dont care what boost I run as long I get 450bhp!
I went pod last night and did worse than with my k04.. I did a 13.4 with my k04 and I did 14.2 with this setup![[:@]](/forums/styles/seatcupra/oldforumsmileys/furious.gif "Furious [:@]")
It was the crap rubber im using and the first time I launched the car in 1st gear so just couldnt get it right! kept spinning 1,2,3
Running 1bar this turbo is too laggy and crap in my opinion! I either bogged down or spun and changed gear so was way out of the power band.
I really want to up the boost but am stopping myself incase something goes wrongso just have to wait till it goes back to pros.

dont get dissapointed yet...its not finished. give it time
as for santa pod....it takes alot of practise. agreed the times are poo but hey....that just means you need to go more
keep it going

with a bigger turbo you have to learn how to drive it again.change gear too early and you'll be off boost losing you time.i got my 12.2 by nailing it in every gear almost hitting the limiterI was running 630cc injectors @ 3bar until today morning when I realised it should be at 4bar

Yeah I know what u mean!
I was shifting at 6k so that didnt help one bit!
What revs are the limiter at?? Is it something that the mappers can adjust?
the mapper will havr set it somewhere.
if you have valve, springs, retainers then im sure it would have been hightened quite abit

way too early mate,take it to the redline and change just before it starts popping and banging.your rev limiter would be 7200-7500 i would of thought.
steve...fwd dont forget....
i have to hold mine on the limiter as its spinning up. there is no way of telling when to change...you just need to learn.
if you change before you hit limiter you will be in 'lag central' in a fwd

and in 4wd mate,having grip doesn't stop turbo lag
this is why most drag cars run ant-lag. i took 1/2 second off one of my runs by changing just before the rev limiter.
steve you said you took .5 of a sec off... as opposed to what? hitting the limiter? or early shifting?
steve..when are you next runnning? i would like to see how our cars compare up the strip
you would leave me like a bat out of hell.....untill i find the tarmac lol
you would leave me like a bat out of hell.....untill i find the tarmac lol
engines rebuilt,new rings etc and new garrett gt3076r is on but when they fired it up there's oil escaping from the centre of the turbosteve..when are you next runnning? i would like to see how our cars compare up the strip
you would leave me like a bat out of hell.....untill i find the tarmac lol
so who knows when i'll be up and running properlylet us know if you plan on going again as it would be good to meet up again and to see your car in actionoh and hitting the limiter.Similar threads
