If you read everyone's posts, your logic is the butt of jokes. At least a few of us tried to help. I'm all for your motivation to mod, but it would be in your best interest to not insult people who give you accurate advice. You think all those mods and numbers are going to equal a 100+whp improvement? So I say again, 1+1 does not equal 2.

And to save yourself some time, nearly all aftermarket exhausts will make similar power as the other. Same for cold air intakes. HFC's come in 200 and 300 CEL count, 200 is less restrictive. PPE and Fast Intentions are the only Long tube headers available. Every shorty header isn't worth it except the Momentum headers. Motordyne intake manifold only gives mid range power with minimal loss up top. No need for ignition amplifier, the car uses direct ignition. No need to grounding kit, you car is new. Pulley's make 5-7whp. And buy yourself an oil cooler. Looking at your previous posts, Whiteline sway bars are preferred over the hotchkis by most, The twin supercharger kit is going to cost you $14,000+ install not including supporting mods. The stock LSD sucks. SS lines, new pads, rotors, and fluid, your brakes will be boss.

Unless your building the bottom end and/or getting exhaust cams, there is not much else to know about NA mods. Welcome to the money pit.

For the most part Firehawk is right. The reality is that the vq37 is pretty much forced to the limits out of the box. You can get some power out of losing the stock cats and exhaust and a tune will help assuming you have all the bolt ons for maximum gains.

An oil cooler IMO was the best mod I did after the GTHaus Exhaust because it allowed me to drive the car hard without going into limp mode. Good luck OP but don't be surprised when the gains are far less than you're projecting in this thread, your numbers are overstated.

also as firewark started, this starts getting expensive pretty damn quick AKA "welcome to the money pit"

Increase quantity of oxygen per unit time consumed

Or

Increase the efficiency of the combustion

Agreed with firehawk. Your numbers are waaaaaaaay optimistic/unrealistic

and their just numbers. AUC and rotational mass are going to matter more.

with all that being said, is TT the way to go? how much TT add weight to the car? thanks!

Not enough to care and offset the amount of power you're gaining lol. With that said, maybe about 100lbs +/- a little.

I would generalize and say forced induction is the way to go if your looking for over 350whp. Both supercharger and turbo options give great results.

Why doesn't anyone suggest N20 when looking for more HP on the 370? Seems like with a proper setup/tune it could provide a viable alternative to other FI options. Not to mention a fraction of the cost.

Nitrous is great but not on the 370 from my understanding. Don't get me wrong, I'm all for nitrous, but I have seen allot of issues when installed on these cars. If I end up keeping the car for a while, supercharge or turbo is my rought. No since in spending thousands on little rwhp adders imop.
