Mods for 500 WHP with Stock DP?

[kevinbonds]

I'm probably just going to aim for around number for now. Anything past that, might as well just go full send

So now you see the light, you cannot make 500WHP on the stock turbos reliably. The best bang for this car is the following mods. Heat Exchanger, Intakes, LDP, Exhaust and tune. On 93 without pushing the car too hard you are at 420-430WHP and 450TQ. The issue with these cars is once you push the car past these numbers you start running out of HPFP and turbos are way outside of their efficiency zone, so pushing to make 500RWHP makes no sense. In my opinion, if you want to get past 430 or so RWHP, just do the turbos and from the get-go and run much lower boost and the car will be much safer.

450-500 is the sweet spot! My last car was slightly higher than that and we were creeping into being too quick.

I had my C7 at 450 and C8 a bit higher...but the torque of the Z is a monster compared to those N/A V8s!

Okay, so say this instead of

Just stating that it's impossible on a catless car. Sure, say that if the block will blow at 450hp. But make valid claims and use the information you know to teach.

Bro, once again I am not going to debate, and yes you will window your block if you push too much boost on the stock turbos, the Q guys do it all the time, so it's best to keep it conservative. We have several people I know locally making well over 600-700WHP on these cars with the proper fueling and turbos.

Some of you will cringe at this but having modified cars for the last fifty years I have reached a point where 400 HP is my sweet spot. My Corvette, Chevy II, And my Z all have roughly 400 or a little more. At this point reliability makes my day. I understand we all have to go through our own learning curve but looking back I can remember 200HP was crazy in a small package, 300HP was strong for a muscle car and 400 was almost a dream. The fact that we can choose any number of hot rods today with 400 plus HP and get a WARRANTY. We are livin the dream folks.....

Very true! Back when super cars had 4-500 HP. Crazy that online no one thinks a car is fast anymore unless it's pushing over 700hp. I blame Dodge

It's a reliable and relatively obtainable target, w/o going absolutely bonkers on mods. Going E85 realistically would dang near double what I've already spent on the car by the time you're done with the full conversion kit, pumps, re-tuning, etc.

Humor me: Let's line by line this because it's my eventual upgrade path. To add E to your setup Cracka would be AMS Flex Fuel kit $1000 and a retune right? Prolly good for 490 WHP on E30. Am I missing something? (probably)

You need a LPFP also. And it may give a little more power, but the key to E-30 is giving a little head room against detonation so you can run a bit more timing.
