What boost is everyone running?

[acidstrato]

think people were getting confused between fly figures and wheel figures

So 19 psi is about average then for most (with a revo stage 1 or equivalent).

There is still some puzzling things with my car then. Not sure what map it has.

I take it Other people are getting 180bhp at the wheels with similar mods to mine then?

no mate, cos those figures, with those mods are beyond optimistic. most people realistically believe that 220-/+ is the maximum that the k03 (stock) turbo can flow. i have more mods than you and im hoping for around 220bhp at the fly!

Some engine's can differ tho can't they. Only found out today i have a cat back exhaust system on it. (rusted powerflow) Not sure how much difference that made

i had a powerflow sports cat on mine. got 190bhp from a std 180 so 10bhp difference. not sure about cat back tho? would it actually make any difference?

 

[acidstrato]

engine can differ but not that much tbh you spec id be surprised if its worth more than 200bhp. rollers differ especially with the cooling but without efficient cool most remapped cars fail to achieve 200bhp


as traumapat has sort of pointed out, a cat back exhaust alone wont do much if anything at all since the real bottleneck is still in place. replace the downpipe and cat and then you should be seeing accurate gains.

i just hope i achieve something along the lines of 220bhp when i run in a few weeks. otherwise my full exhaust system, turbo intake pipe and front mounted intercooler will seem like a pretty big waste of money

* i dont really care what it achieves tbh really though, car feels mint, each upgrade produced a noticeable gain and im happy

People very rarely get over 200bhp at the fly with a standard smic no matter what rollers.

The last time I had the bo****ks to look at the boost gauge as well as the road it was 2.4bar spike but held 2.2. What's that in psi.

 

[beezaturbo]

a hell of alot. what mods are you running??

Thats a 35psi spike then dropping to 32psi!

 

[PhilW]

Its a derv by the looks at it.

 

[Bogwoppit]

Public profile says Octavia vRS

 

[acidstrato]

yeah dervs run massive pressure as standard, let alone remapped

doubt its petrol cos Bills 500bhp ibiza runs those sort of figures

 

[Havok316]

Mines hitting 22psi drops to 20. I have changed the boost to 7 and the timing to 7 and use tesco 99 unleaded fuel. I have a full powerflow exhaust system, carbon maxxflow induction kit and revo stage 1

hehe, same as mine

196 at the wheels??? thats very high isnt it for just a remapped car with cat back exhaust and filter etc?

Sorry that should have been at the fly i do belive.

this is where i had mine r/r'd, the bloke greg was telling me that their r/r has the most advanced cell in the uk and i have no reason to doubt him:

http://www.westonperformance.com/dyno/

Mine made 188.6bhp/240lb at the wheels with revo stage 1.....

 

[__B3NNY__]

Now im confused im not sure if mine was taken from the fly or the wheels Heres my graph my be some body can tell me from that?

 

[acidstrato]

fly mate, the blue line is fly figure, red is your wheel figure

 

[gavthelad]

i was told by the lads at weston performance, and the lads at the dyno dynamics stand at autosport that the way to tell if the power is measured at the fly or at the wheels is to do with the lettering after your power output number. HP = at the wheels but cant remember the fly reading, i think it could be just P but dont quote me.

 

[acidstrato]

u mean whp or bhp

what iv said is correct though, they should both have a similar line graph but fly is higher than wheel since power is lost through transmission

oh yeah, what you said was correct i just couldnt remember what they told me at autosport......so many fit birds wandering around the stands made me lose concentration!!lol.
