Got an 05 with 81k miles with a comptech supercharger kit w/ AC. headers, exhaust. Makes 300whp but looking to get around 400whp.


what extra will I need?

Stand alone comp. thinking AEM
bigger injectors (what size and brand?)
smaller pulley of course but what size? maybe a 9-10lb pulley?

anything else?

thanks in advance.

 

There is several ways to go about this. I have preferred the cheating way myself but I wont recommend that. The best by the book way shows that the AEM EMS is a common and good solution for engine management as long as OBD2 compliancy/Emissions are not needed. If so, Kpro is the alternative. Injector Dynamics has really proven themselves to be the Injector of choice. 725cc/1000cc are your options, both delivering what you need. If you ever want to run E85 in the future, you would be best going for the 1000's.

the 3.2" pulley yields typically 11psi with an 8k rpm redline. If you want to increase your redline to 8500-9k rpm you will gain another 1/2 - 1psi. If you want to keep your redline at the stock 8k rpm then I would suggest going with the 3" pulley. This will insure that you hit 400whp, if you have any other breathing mods or run meth injection you can expect to touch about 425-450whp.

 

thanks for the info.

We dont have emissions here in florida so thats not a problem. We dont have meth or water injection around.

most likely keep my stock redline since it'll be a daily driver

 

I went from 7 to 11 psi about a year ago, and beyond your list, you will also need a better MAP sensor like SOS or Hondata so you can read the boost pressure more accurately.

I would also suggest looking for a better air cooler setup than just the standard heat exchanger that comes with the CT kit. Even at 11psi I was running into pretty noticeable heat soak issues. On a back to back dyno, I was loosing 10 HP between 3 different pulls.

I have a 9psi and 11psi SOS pulley still, PM me if you're interested. IMO then are the best quality pulleys for the money. my 11 psi pulley made exactly 11 psi right at red line, can't get much more accurate than that.

 

Yeah forgot about the map. Probably get a fmic. Trying to mAke around 400 on 93 octane. Do able? I see all the meth 85 stuff but nothing on 93

 

junky is right with the appropriate mods.

but something to consider is:
once you step up the pulley size, you have voided your warranty.

 

With the boost loss ave of 3-4psi with an fmic, You wont get to 400whp easily if ever. You will effectively be maxing your blower speed only to net 9-10psi max. Best rout to take is an upgraded heat exchanger, sticking with the A/C. Leave the fmic with the turbo guys.

 

If you step up to a 14psi pulley or even smaller, and keep the stock aftercooler, you could hit 400hp on a more generous dyno. Heat will be your worse enemy. And I can't remember what the old NOVI1000 unit max out at in terms of turbine output limits.

Good luck, I see a lot of people done it with the Vortech upgraded units, but don't think I've seen that many original NOVI1000's pushing that number.

 

Yeah 53,000 rpm on the NV1000 is max. That works out I believe to a 3" pulley at 8k rpm, about 13psi max. VT has different trim options for their blower which helps boost efficiency. But of course the faster you spin the blower the more heat and less efficient it becomes at making power, quickly diminishing the returns of a fmic. Efficiency wise, a good working A/C is the way to go with Novi blowers in our boost range.

 

Warranty is not an issue since its out. I was thinking fmic because of IAT temps but i knew it would lose a few lbs. so if you're right about the max on the novi1000 of 13psi max.

according to SOS website the 3.2" pulley will produce 10 psi (2.2L). or the 3.0 will produce 11lbs

im guessing the 11lb should be ok? or should i just go with the 3.2 to be safe. This is my daily driver now.
