Loosing boost after a period of driving

[bla1n3]

just a quick question, was driving my remapped cupra tonight driving fine boosting fine after about hour and half of driving, putting foot down didnt seem like there was as much grunt or boost?

left it to cool down for a while about 20 mins

back in and it was fine??

can anyone clear up what this maybe isit common?

cheers

Still on the standard intercooler? If so it probably got too hot as they are crap and then you lose alot of your power.

yes mate still on standard intercooler, just a remap and upgraded induction kit

yeah i get the same problem ( heat soak) pain in the a*se i have got the upgraded intercooler just got to get the pipe work to fit it!!!

 

[bla1n3]

cool, so this is what its down to then, i was getting worried lol so its just the intercooler needng an upgrade to handle it

Have you got a boost gauge? did it go into limp mode when it didnt boost as much? 6-7psi?

 

[TAFFY aka beast]

yeah basicly. the standard intercooler in my eyes is not in the best of places for direct cold air e.g obstructed by plastic etc. get a front mount on there and it will minimise the heat soak!!

 

[bla1n3]

yea i have boost gauge but when it was limp it was hitting about 9 psi?

whats a good safe psi to have the car running at and how would i be able to adjust it?

 

[TAFFY aka beast]

well i no on the leons when they get remaped they hit about 1.1bar which is about 15.69 psi. my m8ts ibiza cupra on here (mr d) when i have been in it hits about 21 psi thas with stage 2 revo. and thas rapid. 0-60 in bow 5.5

 

[bla1n3]

yea well i previously owned an audi tt 225, but the remapped cupra is much quicker on pull off and low end than the tt, but the tt felt alot more solid! so what am i looking that the cupra should be hitting psi after stage 1 REVO remap?

 

[M87NER]

yea i have boost gauge but when it was limp it was hitting about 9 psi?

Who was it remapped by? what does it normally hit when it isnt in limp mode about 20psi ish? normally the N75 valve causes this....did in mine, it will make the car go into limp mode for a period of time due to over or under boost detection.

 

[M87NER]

revo remap should peak 21/22psi iirc and hold a good 18-20 psi upto 4.5-5k revs.

 

[TAFFY aka beast]

he got it remaped by revo as far as i no but it defo hits around the 21 psi area. ill gv him a buzz and find out m8t

 

[TAFFY aka beast]

ye thas it thas what it should hold to. he just had a decat and down pipe put on to. the down pipe on the ibiza are so restrictive as well by the way.

 

[bla1n3]

yea its REVo remapped and yes it hits about 20 21 ish psi boost, so this is about right yea?

 

[TAFFY aka beast]

yepo. what else have you done to your cars then??

 

[M87NER]

yea its REVo remapped and yes it hits about 20 21 ish psi boost, so this is about right yea?

Yeh thats about right psi.....

 

[bla1n3]

REVO remapp, forge Split-R, green cotton cone airfilter, cat back stainless twin pipe, boost oil nomad gauges in piller, green stuff pads

 

[TAFFY aka beast]

nice any plans for the future??

 

[bla1n3]

sorry about the size!!

futre plans possibly, upgraded intercooler, samco hosing, brake upgrade and possibly stage 2 remap.
