Upgrading P1X to…

[80FoxCoupe]

Because people love to talk. There are a lot of p1x cars at 1000whp. A gen3 at 20psi on a p1x will make 1000whp.
the d1x according to procharger can only make 125 more hp than the p1x. If you really really need that 125 then I guess

That chart is simply a general guide. I've made 1175whp thru a 6r80 with a d1x and it wasn't spun all the way up.

Turn it up and find out. Just cost you $100 for a pulley.j

Really!!

Now that's what I am talking about. I goal is actually UNDER this. What was your pulley setup? This is making me look towards a D1X more so now.

Pretty sure that was a 4.0 pulley

Cool cool. Prochargers calculator shows you right at 65k @ 8,000rpm. I'm still VERY impressed even if you were right at max RPM.

I spin the engine to 9k. Went 8.35 at 165.

OH, so you were overspinning the D1x

You could say that I suppose. I just spin it until it does what I want it to do. It's at max speed wherever I stop.

Hahahah. Nice

Are you fully max'd out on the intake and exahust side? Every HP you increase naturally aspirated will yield a multiplier with boost.

As others have pointed out, your blower is certainly capable enough, but it helps to have all the supporting elements in place to make it easier (larger intake and throttle body, ported heads, long tube headers with full 3" exhaust, upgraded valve train to rev higher, etc).

If you can start out with a 500 rwhp motor N/A it's easier to hit higher numbers than if you start off with a 460 rwhp setup. That 40 hp ends up being 100+ of an effect after boosting.

Yeah I’m not interested in doing head work, but I have the manifold, throttle body, and full exhaust as you mentioned. I am also not interested in revving out the car to the moon; 7500rpm on average unless I’m running out of gear.

I like drag racing but I am not a dedicated drag car, but like most, I just want to have something that gives me the ‘wow’ feeling while I am banging gears.

Well, there's no free lunches. If you want 4 digit power, it's gotta come from either a standard setup with a big power adder or a very efficient/high producing setup (N/A) with a modest blower.

You can get to 4 digit power with anemic components (or standard rev limit) if you just add more boost. That's the blower route.

I was just pointing out if you don't want the cost/investment of going D series blower, you could invest in your other components (like head work and rpm limit).

If you don't rev out and your on stock heads, it might be difficult to reach 4 digits with a P1SC.

The other/last option is a shot of nitrous. That has particular benefits, but also adds more complexity. This option is nice because you don't ALWAYS have to run full sauce. You can roll around at like 850-900 on blower only and then have the option of adding in the funny gas to get you those special 1000rwhp rips.

If you want a daily, 4 digit all the time setup and you don't want to do the heads and you're not interested in reving out, then I'm thinking it will either be very tough or very risky (running more timing than is prudent just to reach that number).

Again, no free lunches in this game. Fast, reliable, cheap. Pick any two.

Appreciate that, and I agree with various points you have made.

Not new to the game but new to idea of seeing 1000w - again, one day, with the notion of being 850-900w most of the time. I just want to see that 1000w on a dyno pull and then be good. Mission accomplished. Not so much that I want a car which pushes 1000w on average while aiming for that 8-second pass. My car isn’t a race car, just a fun street machine. Again, I am a stick shift so I won’t be setting any records.

So to your point about head work, sure… but I’m not to that level. Our heads flow well enough (very well actually) stock but like anything if you want that extra ‘spice’ then where else would you turn to? So yes, ported heads, larger valves, cams, etc. I know this all too well coming from the DSM whelm.

Thanks for the write-up.

The stock coyote heads DO flow very well and will certainly support 1000+whp, but as you are aware and as others have pointed out, you have to get to that number somehow. Either by upping the boost significantly which MAY require some springs, by upping the RPM which will definitely require springs, or by freeing up the power capabilities of the engine in NA form, which will require porting intake and exhaust side, in order to take advantage of the multiplication of boost. You are going to have to give somewhere to hit that number, even if it's just for a "hero pull".
