Increasing HP need to know what to do next

[tdotcv]

I have the cobra motor supercharged in the MM currently at 428 hp. I'm getting SW headers and doing the complete exhaust and going for a tune after. I've read some say an exhaust system added 40-50 more hp. My question is since I'm increasing hp is there anything I should swap or add? I used all the parts on the eaton swap list so far except for the fuel pump I used a focus pump but have the gt pump as a back up if I ever need it.

I know some add dual fuel pumps, change injectors, etc...at what point is it recommend or necessary to start changing parts on the eaton swap list for other parts that can handle more hp? I think after 480 hp you need bigger injectors...but what else?

Usually folks are killing the stock engines when they pass the 450-500 zone, but it's interesting you have an engine that can handle it, and worried about peripherals. What's the block rated at?

I won't put my SW headers on without doing the cooling mod and A/F gauge first. 400 -> 450 RWHP. Also planning fuel filter upgrade first.

My trilogy kit came with the 60lb injectors. JDM upgraded MAF to 90mm.

I've heard people run stock fuel pumps and BAP to about 550. Past that they always seem to change it.

Put a 4.0 Whipple on it.

Baby steps first...Eaton, exhaust, new headlights new paint job, rim polishing etc...the list goes on and on

Save money, don't do it twice. :D

I still need to know what I can max out a single focus pump with a BAP unit...I don't think people go with twin focus pumps because it leads to problems with fitment and install.
