L.R.C. Mk3 Cupra Project

[Deleted member 39269]

i removed the EVAP, SAI and i relocated the DV just before the TB. i also bought some bits...

Inlet cam for this setup, exhaust cam will change with a bigger turbo

Great build your got going on!
is there much gains to be had with a new inlet cam?

Also how does your can run using the bigger injectors and maf? As im on a K03's turbo and wondering what else can be done to this setup?

Thanks, i expect to spread the range that the car produce its power

bigger maf and injectors wont give you hp unless the stock items cant support the expected hp (stock maf ~240-250hp, stock inj with 4fpr ~260hp)

a good upgrade would be a stiffer WG (that would help the turbo to keep higher pressure at the upper revs) and the Inlet cam of the 20v NA motor (pt no. - 058109021F)

Finally the car is out with some mods:
Evap is gone
SAI is gone (pump and combi valve still on)
Cold side dv relocation (dv is now oriented as stock)
K&N filter went between battery and fender
All hoses replaced with Venair
upgraded WG of 0.6bar (stock was .45)

the result was a huge differnce!!!
1st CFs went down
2nd with the dv this way is quiter but between shifts there is no lag!!! (blue spring, 4mm vacuum)
3rd it holds more boost at the upper revs

next mods: TB cleaning, K&N cleaning, a cold air feed and a timing tune...

dv question?

on your cold side relocation kit i take it that you have the boost going in to the dv from the side and not the bottom

yes, there is a huge difference on how the dv works not only at wot shiffting but even when i have neutral and i play with the throttle

is it a bad thing would you say?

 

[L.R.C.]

is bad thing would you say?

i think the BEST setup is with boost coming from the side!!! (with n249 bypassed!!!)

yea thats how i will be haveing mine

i mean if you have it with the boost entering from the bottom you are relying on the pressure of the spring to keep the valve closed,if the spring fails then you will have a leak i also think boost in from the side as oem is best even tho i dos look abit funny like that do you know what i mean
