Engine/Transmission (1998.5 - 2002) Horse Power

[nfox]

What does it take on your 24 valvers to get to 500 rwhp? I am not familiar at all with the 24 valvers. I have a friend that claims that he's at 500 rwhp with a box and injectors. I wouldn't think the stock turbo would allow this or the stock lift pump. What are your thoughts?

Lets see, stock 24 valve HO is 245 horsepower, a box can get you 120 horsepower, injectors are good for what 100 horsepower, a K&N filter is good for like a 20% increase, a moroso sticker is good for 10 or 15 horse. He might be closer to 600 hp! Unless he's been on a dyno, I'm gonna guess he's using manufacturer claims and we all know those aren't always accurate.

my 02 24 valve with 4 inch exhust and dd2s and comp box just laid down 363 hp and 862 tq on a mustang dyno so maybe i need that moroso sticker

Nope, you would need a turbo to get there for sure. It might make 500 on the dyno, but on the road, you also need a pusher pump/big fuel lines to do it safely.

Real world is a lot harsher. On a 245hp 24V, the rwhp is more like 220. The fueling boxes on an ETH are more like 90 hp.



You CAN get 500hp worth of FUEL into the engine pretty easily. Some Mach 4s and a wore tap box will do that.



But you'll be pulling a near vacuum at the VP, and the turbo will be 2 seconds from explosion.



You need at LEAST big fuel lines and fittings. The stock turbo MAY be able to spike to 500hp, but EGT will be at or over 1800 and that turbo will not last more than a few seconds at that level. I would bet it's spinning way over 300K rpm to move that.



There's a good chance that 500hp with the stock turbo is impossible. It's just not up to that much fuel.



My truck dynoed 390rwhp/918lb-ft with just an EZ and DD2s. Good numbers? Not a chance. The dyno was using correction factors for the altitude bassed on a NA gasser. Reality is that I am more likely around 345rwhp/830 lb-ft.



ETHs are a little tougher to make HP on because of the weenie pump. Better to go 12V or better yet HPCR if you want the big numbers, IMHO.



Just my dos pesos.

The stock turbo is the real limiting factor, then it becomes the fuel lines.



I hit 506 with BD4 injectors, edge drag comp, baby hybrid HX55, 1/2" fuel lines, and a Holley Blue replacing the lift pump.

Actually, Moroso stickers only work on gas powered vehicles!

I would have to disagree with the fuel lines. With the 3/8" lines, we have seen 580+ on diesel on a 24v, and over 740hp with squeeze, same lines.

im definitly getting ready to order the FASS system. cause now that i tapped the wire, at WOT it can now pull the fuel pressure down to 3 lbs. needless to say since dyno day ive stayed away from WOT. until some bigger lines and pump get over to imlers for me.

I just re read what I typed, I need to do that before I hit the magic button. I meant to say the stock lift pump. I know that there are some people making 500HP with the stocker but based on the LP history that is 50/50 gamble.

Ryan, thanks for the clarification, but I was referring to the lines themselves. With a pusher pump and the proper fittings and 3/8" line, you can support 600+rwhp. You don't have to go to 1/2" line for that.



My truck has our pusher pump and line kit, makes 511/1052 and will not get below 11psi at the pump.

I completely agree. My fuel lines started out as a Wildcat System that I only used the adapters from. After a bit more research I would go a different route now and recomend 3/8 lines. Based on a flow capacity calculator(Parker Hannifin) and some fuel useage calculations, 1/4" lines will support more fuel than a 600HP truck can burn, the rest is used for cooling the VP44.
