Because on jwt's site it says s4's have a slight low/mid range loss compared to S3's but topend out performs. Again these are n/a applications people that jwt is talking about when they say that. Boost is a whole different story.

I dont see s3's outperforming s4's in boosted applications anywhere. low/mid/ wherever. Just not going to see that happening. Again provide proof or GTFO. hahaha

I really would like for a car from somewhere else come down here and dyno. Then dyno and tune.

I mean the cars are running consistently at the track ith their respective whp, 199whp full weight B13 ran= 13.8 @ 101mph, 233whp VET G20=13.4 @ 10Xmph, 284whp full weight B13= 12.4 @ 113mph all on regular b.s. 205/50/15 tires. AC/PS no weight reduction done.

Put the WHP to the side. The red B13 gives 600CC bikes a very good run.

Ashton you get a little shine on here and you start talking rude. Wussup with that?? Remember when you used to post the same shit in EVERYONES threads about your setup and everyone got tired of hearing it? I was still telling you to go for it! So stfu with the bs in my thread man have some respect man.

Anyway I think Gio dynoed his maxed out t25 and got great numbers. Id be interested in seeing a dyno with the same setuo only s4's. Sure it may make a little more later in the band. But I'm wonderimg if midrange would suffer. Yeah s4s make more power at boost levels the turbos exhaust can handle. I wondering about a maxxed out t25 where it can't really push more then the exhaust will allow anyway. So that mega tq and whp spike is where the t25 will shime. Not 7500rpm. So again, I understand what s4's do for regular boost. But this isn't regular boost I'm wondering bout

Just completely out of breath and always caused problems. After 13-14 lbs of boost with s4 cams the t25 is nothing but hot air and backpressures go through the roof. Just not big enough to move that much exhaust gases through the turbine and wastegate.

I wanted to make big power so i went with a T3, plain and simple.


I'm pretty sure that's 100% accurate, one day he woke up and decided to pump the gas in the tank and voila!!!!instant power adder.

I felt the same way when I upgraded to BC cams stage 2 on t28.
Its great on top but for driving around town it sucks!
With the stock cams it used to breaks the tires loose at the lower rpm band too.

its cause they are closer to sea level too prob.

Gio glad your here. Can you post your t25 dyno here?

I am looking for maximum tq here guys. As early in the power band as possible with the t25. I'm talking rally car tq lol. Not worried avout max whp. I have a ZO6 that's much better at top end and gripping while having it. I want a tqey daily.

I never had that issue on pumP 93oct. And I have plenty who can vouch.

There was nothing rude meant by my post. The part of provide proof or GTFO was a joke dude.

Again im not pulling these posts out of my ass. Its hands down that the S4's outpeform stock and S3 cams everywhere. Again unless someone can post proof otherwise which hasnt happened.

As far as maxing out the turbo, the turbo is going to make the same max power whether your on stock cams or s4's. It will just take more boost and put more stress on the motor to do so. But I will say you will have a much better overall powerband with the S4's no questions asked. Why do you think Gio wants to still put cams on that motor that made 325+whp on a T25. Because there is still more overall power and better powerband to be had.

Nothing rude meant by my post Johnny. All I can say is I learned a long time ago to stop messing with the T2's because i was wanting to make alot more power. The t2's especially pushing them to the max was nothing but a headache and problem after problem. Had nothing to do with the tune. E85 had everything to do with the ability of the T2 to make that much power without melting a piston/pistons
