they are right; its past its efficentcy point. Where do you redline at? At what point does the boost go down? Its a tradeoff of a small turbo; less boost at topend. Im putting a teo4h on my teg and people say its too small and crappy. Maybe you could try shifting eariler ahhaha. Small turbos are great for autox but it bumps you up in class

 

redline 6900 rpm ONLY

1.6 S O H C vtec small engine


it drops like 5500 or after vtec on 2nd gear.. 3rd i don't think it drops much

could this be boost leak?

 

does it feel like its loosing much power towards redline or just that the boost isnt as high

 

dunno, everything is pretty fast at higher rpm....

it's still boost.. like 5-6psi.. not like NO boost.. yeah it feels fast still

but watch my wording... "FEELS"

 

im leaning towards the turbo being to small. when does it spool

 

where is your wastegate actuator line sourced from? Put it on the intake manifold so it'll keep boosting till you make 8psi in the manifold.

 

take off your air filter see if that does anything. seriously.

 

ok starts to spool almost like 1500-2000 rpm.. fully by 3000 or so....

wastegate line is RIGHT OFF THE COMPRESSOR

filter hmm.. i'll try all of these...

 

try sourcing the WG from the intake manifold.

 

if u run with no waste gate line your bov is still going to blow off at its set psi unless u have a aftermarke one. ive seen alote of stock cars with the wastegate line ran right off a charge pipe but that would be the same as the intake i suppose. but if your still making some boost till redline then thats what it should be doing. all stock turbo cars do the same. g/f's vdub makes 8psi from 3g to 5800rpm then it slowly falls off red line is 7200 on the car by the time u shift its making around 4-5psi but is still pulling hard all the way thru. i think your set up is fine.maybe try a bigger turbo and see what it does but i think your in good shape
