Maf g/s Readings

[HAR80N]

Hello Just Seeing What Peoples g/s Readings Are And What Would A Custom Code Phase 2 Tune Read Thinking Of Swaping Tunes I Have APR Stage 1 Tune Miltek TBE Seat FMIC Forged TIP PD160 K&N And Read 179.8g/s In 2nd Gear Just Wanna See If Its Worth The Upgraid Thxz.

You should log it in 3rd gear really. Give the turbo chance to get loaded up. 180 is pretty respectable, you need to do a run from 1500 revs to the redline ideally. Peak numbers don't cover it.

I'm CC phase 1 with dump+cat, stock cat back, stock DV, stock airbox +filter but with a 3inch feed, ebay spec TIP, stock IC but w waterspray and better air ducting, ported wastegate path in the stock turbo, turbosmart IWG75 wastegate actuator and some pneumatic mods to the boost solenoid to limit peak boost to 19psi. I was getting 189-191g/s at 6Krpm on the 7psi actuator spring in 3rd. Now I'm running a 12psi wastegate spring so top end should be stronger still - certainly felt it but I haven't had a chance to log it and check AFR's. But like Gav said its more about the curve than the peak. Plotting g/s against the 3rd gear rpm range would tell you more about the tunes overall effect on the torque curve - haven't done that either because I'm a bit of an excel graphing moron.

actually mate PM 'noone'. He went from APR stage 1 to CC phase 2 and seemed to be a convert. He was always pretty approachable and would share his experiences for sure.

my bestfriend has a polo gti aswell and we are slowly doing his up and i told him about the custom code tunes and thats what path his gonna take so ill wait awile tell he has finshed then ill take his for adrive at the moment im happy with my car but im always looking for more power lol i beat vyvzvevf ss's lol mazda mps's the other night i raced a 2011 wrx hatch and was pulling away from it i love the wow factor the ppl give me after we race best race was a fg xr6 turbo i was pulling on it 1st and 2nd then missed 3rd and it got half a car in front and couldnt pull away hehehe

[HAR80N]

mines boosting at around 16psi will it show more g/s in 3rd lol i hit 160kph if i rev out 3rd all the way ill give it a test lated hehe

[sambb]

yeah don't be silly with where you do it or the men in blue will keep your car and maybe even you. If you look at the brisbane dyno day threads, the graphs will generaly show the stage 1 APR tunes boosting less than the CC ones. But you can't read too much into it because they may be making their power with leaner mixtures and more advance - you just don't know. What you can do is keep going with supporting mods. The air in - air cool side of things seems to be handled already but you could start hunting for mufflers, cats, dump pipe flanges and picking a few exhaust guys minds, testing your wastegate to see it isn't cracking low etc so that when its CC2 time you are ready to rock. Louis19 might still be selling his 2.5' dump+cat.

Louis19 might still be selling his 2.5' dump+cat.

Nope, sold that to Altec a while back along with my CC Phase 2 ECU.

i just a catless 2.5 inch dump and catback exhaust the miltek one and i put on a gfb mbc but set in fully closed cause it has the smaller hole in it so it slows down the air to the wastegate i picked alot of spool time down low i was looking at getting a thermal gasket for the intake manifold that once u stop and turn ur car off that manifold heats up super fast i get 161g/s at 3500rpm in 2nd i still got to test it in 3rd

[sambb]

oh ok so you have a full exhaust system already. So how is your MBC set up. Is it parrallel to the N75 boost solenoid to keep boost down or did you remove the N75 entirely and now run the MBC in line with the wastegate hose in an attempt to get boost up?

[HAR80N]

the BJX has the small port intake manifolds dont they and was thinking of fitting the ATP Exhaust Manifold and port it alittle was gonna pull the intake manifold and port it and coat it black and put on the thermal gasket

[sambb]

Not sure on the intake manifold manifold side of things. The stock exhaust manifold is pretty restrictive though. I had it off when my head to manifold gasket went. My mech heavily ported cyl 3 runner to get it close to what the others were flowing and also needed to port match between exhaust manifold and the turbo where there was a decent step up or down - can't quite remember. Seangti went from an aftermarket exhaust manifold back to a stock ported one I think and still lost some power I think so there is a fair restriction there. The restriction is probably less of an issue with the stock ko3 but if your going to a hybrid or ko4 like he did then it may be holding you back measurably.
I'm not denying there is an issue with head to manifold heat soak after you park the car but I woulnt obsess about it. The issue is if you've been hammering around and then stop for a feel and the manifold is hot then. Your ic should be keeping it cool when you're underway yeah? Try insulation wrapping your ic to throttle body hose to prevent heat soak there. As long as your throttle body is cool to touch, you know your induction air is arriving at the plenum cold. It should move out of the plenum pretty quickly without picking up temp from it since its a large body of mobile air.

[HAR80N]

yeh i was only gonna do that intake gasket cause i wanted to paint the manifold and rocker cover wrinkle black but yeh my intercooler works really really good its the airtek seat cooler keeps the air stone cold. i have read up alot about the exhaust manifol ppl swear by it but the first model of the atp manifold cracked alot and havnt been able to find much on the new atp manifold but you can just see from the design of the stock manifold it would kill flow and make for more heat i love the JBS manifold but cant find them anywhere to buy one i love my polo hahahaha

[h100vw]

I wouldn't bother changing the manifold unless the turbo is coming off anyway. Far too much of a hassle to warrant the effort. Certainly if you're not fitting a hybrid. Don't think that Sean's car isn't quick even with the std VW manifold on, it is.

Only place you'll get a JBS manifold, is direct. I couldn't save you any money on one. It would be easier to fit though.

I highly recommend CC Phase 2 over APR, for the Polo the CC tune is more agressive.
Have fun, but there is only so much power the Polo can deliver, gains after a dump pipe and PD160 intake are marginal on the stock turbo. Still, loads of fun with the right suspension work and tyres.
