S about 6 weeks ago I had a Maggie 2300 installed on my ss with the canned tune. While I can definitely feel a power difference I'm extremely underwhelmed with the performance. Just for baseline stock I had 408hp 406tq and after the supercharger o got to 508hp 508tq. So that being said my speedshop told me that they. Could put on a smaller pulley 9 to 10psi boost, rotofab Cai, and a custom tune and get around 600whp. For 2k dollars. So my question for all of you is should I do it? And will I feel underwhelmed by the power again? I only say this because I was not impressed with 100 extra hp so what will be 100 more? Also do you think they can make that much more power with those mods?

Do you have fuel mods? You might exceed the factory fuel system with the smaller pulley, food for thought.

What octane are you using? Adding boost might not do anything but the tune will be helpful. 9psi on 93 should make more than 508 but remember dynos all vary and are just a tool to help tune.

The stock air intake is solid i would look more into in tank fuel, injectors and hpfp maybe try to get some flex fuel to increase octane.

The ss said I do not need any fuel mods unless I want more power. Than 650whp

So I'm at 6.5psi now on 93 octane at 508hp

My next step after this is fuel system and e85

Well if you have a factory fuel system, many SS have run out of fuel anywhere from 550-600 rwhp on the factory system with a blower. I'd do a little research before setting anything in motion.

508 is slow, I would be disappointed too. A FBO e85 car could probably gap you.

If it were me i would upgrade upgrade to LT4 fueling and add an aux pump, pulley down run some ethanol and be done with it.

I dont feel like going through adding minimal bolt ons and a tune is worth it to get from 500 to 550 or 600 and then having to add fuel and another tune to get to a good power level is worth it, if you are disappointed with 500 you will be disappointed with 600.

Why do you say I'd be disappointed with 100 more hp? Please explain. I am not doing the fuel system because it's too much money. If the speed shop advised me I don't need it right now why would I do that? I'm not being pissy about this I am just curious as to why you think that.

Only because you were extremely underwhelmed with the increase already.

Depending on how you are using the car, but especially if you are drag or roll racing it, the car is somewhat on the heavy side and 600 whp is not super fast in this car.

I might be wrong but my car was 530 on 91 octane before i added meth, flex, cam and some other stuff and when i am on 93 now vs ethanol been the car is kinda slow. I imagine on 93 it is around 600. If i were to do it all over again i would have just done large fuel system upfront with a supercharger and think i would have been really happy. Also my car is an a8 auto so if you are manual or a10 ymmv

Also for what you are looking to spend another 2k for minimal increase it just seems like setting yourself up for failure vs spending 2k maybe 2.5k and getting much larger gain and also having the octane to support the high compression lt1 with boost. Some people have had ring issues and the additional cooling and octane could pay dividends vs more boost and no octane.


I was also just joking about the fbo car gapping you, you have a sick setup.

^ some wise advice, do some research, take care of the fuel upgrade problem and let the blower work.

[Pete328]

OK well that's all good advise. I guess I'm just going to have to be happy with what I got at the moment. When I want more I guess I'll have to buy a Bugatti. ��

[Pete328]

I feel like I should have done the Cai and custom tune in the first place. Maybe I would have gotten to 550 anyways
