    Long Tubes a waste on N/A cars.

    Whatever - go out an buy LT's and get your gains from 5500 rpms to redline. I'll stick with my stock manifolds, bolt on a TB/plenum and add some more power in 30 mins. flat. I can't wait until it gets warmer outside so I can start posting my trap speeds with my weak, headerless, 250 rwhp GT.

    Yes, the LT's produced more avg. rwhp than my curve FROM 5500 RPMS TO REDLINE! Where the heck do your shift your GT at? I was told the avg. rwhp. would be higher throughout the entire graph. 5500 rpms to redline is hardly the entire graph. What about the loss of torque on the LT...

    Long Tubes a waste on N/A cars.

    I am comparing what I was being called out on - my 250 rwhp car WITHOUT LONGTUBES compared to another 250 rwhp car WITH LONGTUBES. I was told there would be a better power curve and more avg. rwhp. for the car with LT's. Well, guess what? There wasn't. For the last time, the stock...

    Proved this wrong too. There wasn't a "better power curve" on the car with LT's as you put it in your words. Still searching for that "better power curve".

    This is what I proved wrong.

    Why isn't it a good comparison? Perhaps you just don't like the comparison results. It's pretty simple to compare: Dynojet vs. Dynojet SAE vs. SAE 99+GT 2V vs. 99+GT 2V LT's + midpipe + CB vs. x-pipe + pullies + CB + MAF + dynotune 250 ish peak rwhp vs. 250 ish peak rwhp RESULT -...

    Well, since I still have received Cottonburnerz or 03trublueGT's dynojet files I did the best I could. I printed off 03trubluGT's dyno graph because it had the higher numbers of the two and was the easiest to read. I used a ruler to pull my data from his graph and compared it to my...

    That is exactly the type of response I expected to see. No, I was told (by many LT owners) that LT's are all about avg. hp. So, now I am trying to show everyone that the avg. LT hp is no different then the avg. hp. of a car without LT's - however, both cars having about the same peaks...

    Cottonburnerz and 03trubluGT: E-mail me your Dynojet files to - [email protected] I will put all of them on one graph for everyone. I would have suggested this earlier, but I figured most of you will think I manipulated the data to make my graph look best. I will be glad do to the...

    I'll tell you what, I will e-mail you my dynojet graph tonight. Just provide me with your e-mail address. This way you can post my graph against Cottonburerz and 03trubluGT's graphs and prove me wrong. So good? I can hardly wait. Please PM your e-mail address so you can teach me how...

    I thought this was tech. Is this the best you can do? Because I don't agree LT's gain much over the stock manifolds N/A, that means my car will be slow on the street and the track? You really got me on that one. Yeah, my 250 rwhp GT is probably slower than a 250 rwhp GT with LT's.

    Yes, LT's flow very well, but so do the stock manifolds in naturally aspirated engine conditions. Sorry, but I'd hardly consider a GT with 250-260 rwhp a "race" car. We are not talking about GT's with blowers and 350+ rwhp. I am sure LT's would see good gains over the stock manifolds on...

    Long Tubes a waste on N/A cars.

    STD vs. SAE made a big difference on my car. My car: SAE 250/292 vs. STD 257/300 Now it's only about 2 or 3% difference, but it pretty signifcant against a big number (3% of 250 is 7 rwhp) Anyway, nice numbers and thanks for sharing. By the way, if the shop e-mails you your...

    Long Tubes a waste on N/A cars.

    Both of those cars run off the stock computer program? Anyway, to be accurate, so me 250 rwhp without a cat-back exhaust. I guarantee the Magnaflow CB added power after the headers and mid pipe changes. I am just going by what 5111 posted: Longtube 250 rwhp: X or H pipe (needed for both...

    I'll assume your numbers at not SAE corrected. If your produced 236 SAE rwhp with just pullies and CAI, then you have a factory freak. Most GT's dyno SAE around 223-225 in stock form. That means your car gained anywhere from 11-13 rwhp SAE from just pullies and a CAI. Amazing.

    On 10/28/2000 my car ran 13.89@101 with drop-in K&N filter, pullies, and Borla cat-back. My car might have been making 235 rwhp at that time, but I never dynoed it back then. I can assure you don't need 250 rwhp. to trap at 101 mph. My car trap speed that day was between 100.3-101.9 mph. The...

    Yes, by dyno tune I mean tweaking the a/f ratio and engine timing while doing pulls on a dyno with wideband O2 strapped to my exhaust pipes. My dyno tune was group tune. We basically rented out the shop for the day. It was long day if you car was last. Luckily, my car was tuned second. I...

    Then you need to add $350-$400 to your list for cat-back. Now you are at $1,250 - $1,300 for your 250 rwhp method. That's more than my method and that's assuming a $500 dyno tune ($500 is a very expensive tune for bolt-on mods.) My $250 dyno tune included my Autologic Chip and seven dyno...

    C&L Mass Airflow System?

    If you plan on dyno tuning your car in the future don't bother with it. The stock MAF is fine. I basically wasted $250 for a K&N filter since my tune took care of my a/f ratio. But yes, it does make it's power by leaning out your a/f ratio.

    I beg you to show me stock 5 speed GT with only an x or h pipe and LT's make 250 rwhp with EVERYTHING ELSE STOCK AS YOU LISTED ABOVE. By the way, a $500 dyno tine is insane for a simple bolt-on mod. car. I paid $250, but mine was a group tune. I could maybe see $350 to $400 for a bolt-on...
