Fuel regulators
 

With christmas around the corner i was wondering what to get.
i was thinking about getting a fuel pressure regulator for my 96.
if i do, will i need to get a new fuel pump to up the flow?
also with my current mods (in my sig) is it worth getting?
if so what pressure should i run it at? (or rather what pressure should i not run it at, cause i dont wanna break my car)

im also probly gonna grab some bbk shorty headers and a mid pipe.
thanks to anyone with insight.

you dont need one with your mods. I would get full exhaust or start gathering parts for a PI head swap if you are going to do that (which you really should).

A programmer would help. I had the hypertech for my 96' and loved it.I also had a F.P.R.,but could only go up to 38 psi. With the programmer it would run rich at psi's over that. If you have the cash to spend heads would be the way to go.

Hypertech is just like Jet and superchips. They are all generic basic crap tunes. Spend your moeny on something that will actully make you faster.

non-pi engine so get heads and intake or for cheaper try a set of XE270h cams.

i was looking to do something other than heads, i want to do everything that is easier to install first. i guess ill finish the exhaust work. i was worried that i might be running lean with the intake work. ill do the exhaust then some 3.73's or somthing. also with 3.73's ill need to get a programmer right? which one is the best? thanks for the help

Well the best tihng you will ever do is the PI head upgrade. But exhaust is and gears a re close 2nd in your car. And a tune is gonna be needed. SCT and Diablo are good.

Say what you will,but I'm here to tell you the hypertech made a difference in my non P.I. GT. The P.I. heads are a good mod,but you have to remember its torque that wins races,horespower sells cars. The defference in torque between a non P.I and a P.I. is only a few foot pounds,like less then 10. Heads are alot of money for only a few ft/lbs of torque.

have to seriously disagree. I don't find any of your statements true.

hp is work done over time. hp wins races. tq breaks inertia. get the physics right. yes you can win races with tq, diesels do all the time but HP wins races. Tq gets you going that's it... force changes inertia.

hypertech and Superchips both are better tunes than stock most times but they're still crap. ONLY a custom tune is any good for any particular application. PI swaps make npi engines realize a lot more than 10tq.. closer to 20-30 on average from the cars I've seen pre and post swap. Further, NPI GT's respond better to any bolt on or handheld tune than PI headed cars but they still don't equal anywhere close to the potential of a PI headed or better yet 3v or 4v.

Having had custom and box stock tunes... custom FTW. box stock is a random guess by an unconcerned party about the status of a complex system... you'd think some interaction would be proper to get it right.

Torque is the force that moves the car. A stock 96' NON P.I. pulled 295 ft/lbs in stock form. A 04' P.I. was only 302ft/lbs in stock form. My auto GT with the mods I had was able to take a P.I. 5 speed GT. Guess those 45 extra h.p was on a break that day.

But all I'm saying is the P.I heads are alot of money for the gain. I'm not saying its a bad mod,just costly. Its not my money,don't care how some one else spends there's. Hell,just port the heads you have and save a few dollars.

It isn't just all about peak torque or where it's made. The shape of the curve is more important. For example, the perfect engine would have a flat line for torque while the hp should be a linear progression across the rpms. It's true that the NPI heads are better for low-end grunt but they also die out very quickly which is their problem. The PI heads on the otherhand keep going and don't start to die out until the upper rpms where hp starts to take over.

I think the driver had more to do with your victory than his cars tq production.

Don't get me wrong.. a torque biased car will accelerate and torque production does affect 1/4 mile times in a big way. If it didn't I wouldn't be putting a PI headed 5.4L in my car. BUT even with all the tq it'll make (should land around 325rwhp/ 370+rwtq) it'll still get flat whipped by a blower car that makes just exactly as much tq in about the same curve shape but has 100hp more than me.

As for the money... meh you've got a point. It's a minimum of about 1500 bucks to see a PI swap on a nPI car. However... seeing 280/310 from such cars is not uncommon so I don't think the dollar per hp ratio is out of line.

PI Swap: $1500 / 60hp = $25hp
Nitrous: $550 / 100hp = $5.50hp (now that's a bargain)
Blower: $ 4000 / 100hp = $40hp

Now.. since he wants to stay out of the head swap game... I'd say, "You're leaving the single best power mod for NPI cars on the table..."

I thought that the "Horse power sells cars,but torque wins races" was from an ad that Olds had in the late 60's. Turns out that it was Carroll Shelby that said that,but I guess you guys think he was wrong.:worship2:

wow you guys sure made that clear for me. anyway the PI swap is the last thing im gonna do to the car. just cause it cost $$$$ . thx though :worship2:

and nobody ever accused carrol shelby of being anything more than a chicken farmer turned race car driver. He's certainly never been confused with a physicist.

And you are......?
