Exclamation Add On

So I am adding more mods to my car -

TSP Stage 3 Cam with VVT delete
25%powerbond pulley
ZL1 fuel pump
Corsa Extreme Cat-Back
Full-Suspension
Bigger tires
Connection Pipes
3.91 gear ratio

Was wondering should I go up in Fuel injectors size - cause I believe the stock is 42lbs?

my target goal at flywheel is 600hp with 8 injectors, BSFC .5 and 80% duty cycle would put the injector size to roughly 46.9lbs/hr

Wait, 600hp without forced induction or bigger block? Not gonna happen.

ZL1 fuel pump isn't needed nor injectors...UNLESS you are doing e85, but then you are gonna need more stuff.

Also, with a 2013, I wouldn't do the pulley, you already have electronic steering so you don't lose nearly as much as the 2010/2011 cars.

What does 'full suspension' mean/entail?

600flywheel not to the tires. I was using the calculators from FIC to look at injectors shit.

I already have the pump and pulley system in so there are going into the car

Control arm, trailing arms bushing, toe rods, sway bars etc.

Assume 20% drivetrain loss, so 600flywheel you'd need 480 RWHP?


I haven't heard anyone at 480 RWHP needing upgraded injectors, but it's your money.


GPI has some good info on it:

That is why I am asking on here for advice cause I'm already at 468 to the tires. Just getting more information. and the fuel pump got it cheap so couldn't really say no it not buying it from a guy I know.

Ok, what is your goal with this car? Daily? Track only? Mix? If mix, what percent daily, what track/strip?

Kind of a the mix because I would like to take it to the track, nearest one is a bit of a drive, I have my truck also. So the car doesn't get driven in bad weather, stored in the winter.

My ultimate goal will be eventually Supercharging my car but First I have to first school, almost done, that why I been doing little by little or just the "small" modifications first. If that make sense

Small mods aren't heads/cam/gears/and all the other stuff you've done.



If you are gonna SC I might hold off on the 3.91s otherwise traction will be HARD to come by. Well, that is unless you go with a Centri...

600HP N/A can be done with the right configuration and supporting mods. Before buying random parts my biggest advise is to blue print the build and start with supporting mods you will need and how much drivability you can sacrifice. Cost wise can get near boosted cost just give your self a realist goal for the car.

What heads, cam lobe profile, head gasket, lifters, valvetrain etc... are the main things to look into. I'd be happy to help if you need someone to bounce ideas with. I've done it all and have helped other people meet their goal. N/A stuff is my bread and butter

I was a little over 500whp on my build with stock injectors and fuel pump. No problems so far.

I'd leave the fuel system alone until you go FI you will be fine NA. If you get injectors now you'll be buying more when you go FI. I can attest 3.91's will be rough on traction. I have none in first now and fight traction in 2nd with 3.45's

How did you get your car to make all that torque?
