Best mod on gen5 engines is a flex sensor and tune if you have E85 available in your area. Should be able to run close to full pump E on a stock car...as you do mods you will have to mix the E content down which doesn't cost much for power just adds the hassle of mixing. Long as you can run E40+ the benefits of E will out weigh the hassle of mixing. 50/50 mix of pump E85 and pump 93 will land around E52. The flex tune will make all the changes to the tune so all you have to do is fill it and monitor the E content to make sure the system doesn't have too much E in it.

Look at it like this...A cai, headers, tb, and 93 tune car will make the similar power(620-630whp) as running full pump E on a otherwise stock car. If you do flex fuel, headers, cai, ported tb, you will probably need to mix the 50/50 as I mentioned above.

The car will make more power consistently on E being it will be able to maintain full timing at higher Manifold temps and overall much more resistant to knock vs 93.

Hows traction? I wanna be able to ride on some good performance tires year round, dont wanna have to use slicks, Also what range do you think power becomes too much/unuseful for some regular pilot 4S or pirelli p zeros?

Personally I would not pulley the stock blower nor would I bother with porting it. If you want more in the way of boost then I recommend going straight to the 2650. That way you will have much more potential in the future when you decide to mod even more (cam, ported heads, etc).
Sorry dont really understand boost, thats relevant to the supercharger Im assuming? Like how much boost is going into the engine or something?

Can only speak of the goodyear supercar 3r's and they feel like they're on the edge of traction hitting in 2nd at 4k rpm. Feels like the right amount of power for the vehicle, hits hard but your confident its gonna hook with minor slippage. I also have full SPL suspension parts as well as BMR front cradle brace, driveshaft tunnel brace, and strut tower brace. Feels like removing some of the rubber in the suspension and the stiffening of the rear has made it rock solid.

Boost is pressure the supercharger is pushing into the engine. Different size supercharger pulleys or balancer pulleys will change the boost going into the engine. Raising boost will result in more hp but creates more heat, especially with the smaller stock blower. Because of this, the extra hp won't last long and result in more engine heat soak, which will lower power for the following pulls. Lowering boost will have the opposite effect, lower power but more consistent pulls. This is my understanding anyways

I drive mine year round on 4S when temps are above 40F. Traction can be a problem below 60 mph at WOT, but you quickly learn what you can and can't do.

Oh okok good description, so Im assuming this is why people have ported blowers?

Went with it because I'm not going any further with fueling, porting the blower has also helped low the air temp going into the engine as well as add a little boost.

My Kong Stage X is in process so I'll soon see what difference their super-duper version makes in performance.

Yes will definitely be interesting to see the power difference between their regular port job and the x version. Pretty much finished up tuning, definitely can't run 37% E, high side drops as I have no cam. Thinking 30% E is gonna be the sweet spot with my build pushing about 13lbs of boost. These pulls were in ideal conditions, about 47* outside, great DA

E-something, maybe 60-85 will probably be my next mod along with the necessary injectors and pump ... depending

As long as your cam has the bigger fuel pump lobe, and with your added low side support, you should be able to run a good amount of ethanol i would think. Only thing holding me back is high side which would be a cam upgrade. Maybe down the road but not anytime soon, time to dump more money into our house haha

Won't happen. Will need bigger injectors/pump and/or port injection.

The former. Which fuel pump are you running?

Porting the blower increases the efficiency of the blower thus creating more power.
