My results the following week on e64 in negative DA, the track went away after my first 2 passes when the dew started coming on. The dyno pulls were done with e85 in the tank.

very cool...

I'm hoping to get into the 500hp club with my setup soon. I have Texas speed headers, borla x-pipe and ATAK axlenback. Soon to come is MSD manifold with Katech throttle body, Flex Fuel sensor and tune. You guys think I can get there?

Most likely no

But it’s just a dyno number. It’s not going to change how fast your car is

But it will make your penis bigger

Just tell everyone you have 505RWHP. They will never know.

I would rather Dyno lower and go faster...its a better look when your 450whp rig pulls a 500whp car.

+1

Facebook is littered with guys trying to chase a number. Knowing that the dyno is only a tuning tool, I didn't care what it said. It's alll about the slip.

Could probably do or get very close with the following...

-2in headers - catless
-ported MSD intake
-Katech 103mm TB
-ATI 10% underdrive pulley
-RF Dry
-E85 sensor (and tune)

might not hit 500whp but could be VERY close (assuming 6MT - not sure an A8 would do it - but an A8 is faster in the 1/4 regardless)

Find that same dyno and do all the bolt ons and 500 range is guaranteed. You can gain 30-35 rwhp from just a good E85 tune

I’ve seen other gts with those mods and they run 470s-480s range more typically

The mods in my sig should be good for 480-500 rwhp range. If you dyno an auto and use 5th you can drop 20-25 off of that estimate

Also if one runs a car and doesn’t use sae correction you can inflate the numbers by 10-20 rwhp as well. They don’t show the correction on any of the 500 rwhp gt that ive seen. Kinda fishy imo

I’m getting a dyno done on the 7th I’ll post results

How bad is fuel mileage drop with E85?

I’d like to know if a 103 would even benefit a bolt on car.

Does anyone know?

I’d be worried it would kill velocity too much. Possible pick up a few hp way up top and slow down everywhere else. Car may go slower in the end...

Would love a dyno test from someone lol

I haven’t got exact numbers. I think it’s about 30% less efficient. I average about 17-18 mpg combined city and highway driving. Spirited. With no afm

I'd say a ported stock TB vs a 103mm would be the only argument to make in that list honestly.

I feel like it'd lose a little low end in favor of top end.

To quote tony Mamo, these aren’t your grand fathers gen I sbc. You can’t put too big of a carb on it nor can you have too much air flow going into the motor.

So I don’t think the question is “will it hurt performance?” But “will it gain any performance?”

As soon as msd gets back from being mamo’fied, I will be happy to do a back to back with a 103 and stock throttle body. (If you want me to do one with a ported one, then you have to send me one. Lol)
