depends on how much power you're running... if you are naturally aspirated then you probably have a point. I probably picked up about 40 rwhp or so from the header swap, but I have alot more exhaust flow going with my set-up. I would have a very hard time believing your tuner that has the 700rwhp saleen is not running longtubes or would make only 15 hp with longtubes.

 

I don't know how much hp his car has, I said he has tuned high power cars. Also, I saw magazine tests of longtubes on a supercharged car, and while they did pick up 40hp, it wasn't until 6,000 rpms. From 5500 and below, the gains were all right around 15 or less. I'll try to grab the article.

Read it, at 6,000 rpm they got anywhere from 26 to 42 depending on the brand, and below that it was anywhere from 7 to 19 gained. IMO, that is only worth it for two things, the first is bragging about numbers, the second is if you were racing all the time. However, this doesn't really matter since longtubes are out of the question for the OP.

 

Whaaa!? Cams are at least $600, the most expensive headers, are $1400. That gives you $800 to buy shorties and pay for a cam install. What do people around you charge for an install? If you are doing it yourself I can understand, but your statement leads me to believe you're going to pay for it to have them done. If so, you have some good shops because places around here want $500-700 to install them.

If you want the best scavenging you should look for longtubes that have velocity spikes. Now I may be biased, but a good tuner in my area loves the ARH because they give the most gains to any other header he's installed, therefore it leads me to believe they have the best scavenging effect.

As stated before longtubes can be an easier install than shorties. If you can do one you can do both!

 

You have to realize that I had my Detriot Rockers installed a couple of years ago. Long tube headers and catted mid-pipes were more expensive then (around $1500 - $1700 installed for good ones).

My JBA ceramic coated shorties were $360 and install was $180. My cams were $600 and Blow By Racing in Boca Raton installed them for $400. Brent provided the tune update for free since I have purchased all of my performance mods from Brenspeed.

 

Wow dude, you got a steal on that install price for the headers! They take more time than cams!

Most shops around here want 400-500 for a header install.

And that's why I've done it all myself, haha. Good deal man.

 

Seriously, $180 for headers installed?? I'd be all over that. I never would have done them if $180 was the price! Wow! Even the inexpensive guys up here are $400+. Not bad on the cams though. They seem to run about 250-300 around here.

S197 - Yea, 500-700 to install cams? Tell them you only want one car done, not 3 of em!!! Jeez! LOL

 

unfortunately he is right, I was quoted 400+ parts like gaskets and oil and then another 200 for a tune on my cam install. I did them myself after I was told that lol

 

Would this still give the same or better low to mid range tq as really good shorties? LT's require a good mid, I like my stock, I'd actually like to be quieter (blasphemy I know), I have 0 desiire to be at any "right" sound, I just want to get more out of my car power wise. Specifically the cheaper the better. If I can get 10rwhp/tq out of good shorties for like $300-500 as opposed to the insaneness of the usual LT install for 15 total, I think the first route would be better for me. Especially as I want the 0-60 see-ya-bye, not really for weekend constant 1/4mi runs.

 

I felt 0 loss of low-mid power with my longtubes. I'll check my dyno graphs but I'm 99% sure I gained through the entire rev range.

Roush05 is installing some BBK's this week, ask him how he likes them and maybe go that route as they are a cheaper longtube

 

Yeah, I sure am. I just got back from visiting my mom for Mother's Day and they had arrived. However, after looking at them and doing a little reading, they require a flanged midpipe, so I can't just cut the one I have. I'm gonna look for a shorty o/r x pipe on the forums and try and get one here by wednesday or thursday to install it all.
