Well, I went down to Unlimited Performance today to get the car Dynoed since I got the headers/exhaust installed to get some updated numbers and I was pleasantly surprised! This was on a Maximum Dyno and I was told by Brent that the numbers would be lower than a Dynojet or a Mustang Dyno, but it is faily similar in comparison.

Number before on a Dynojet with TB, Plenum and CAI: 245 RWHP 285 RWTQ.

I can't give you all of the goodies yet so... Photo Op!







Ok, Ok.... Here we go!



Final Numbers were: 266.1 RWHP and 340.5 RWTQ!

Only upgrades from what the car had before was the Bassani Headers, Hi-Flow cats, X-pipe and Borla Stingers. The Final two runs were done directly after the first, so the engine was getting heat soaked, plus there were no fans or anything to help cool. Thankfully it was a pleasant day @ 72* with a slight wind.

Needless to say, I'm pretty happy with the numbers, especially the gain in TQ. I didn't expect a huge improvement in HP, but the 55'lbs of torque was a great outcome!

 

Very nice. Gotta love the TQ.

 

Congrats dude...that TQ is incredible for the mods done.

My old car is a beast. noice.

 

That is a really weird dyno graph. But the numbers seem pretty darn good and right along with what I would expect.

Needs a 100/125shot though

 

I'd like to see how this translates into track time. Nice improvement though!

 

Nice.... Love the pics also...

 

there is something seriously wrong with your torque... 266/340 ? lol... no one makes 80 more tq on a NA Bolt on motor.

 

Dunno man, when I owned that car... It did 288+ RWTQ with just a CAI, catback and a tune.

 

I know your're jealous Stephen. There is nothing wrong with the numbers, the dyno was correct. There were 6 other cars dyno'd, three of them had been dyno'd on a dynojet a few weeks prior and their numbers were just slightly lower on this dyno so if anything my numbers are slightly under-rated. But thanks for trying!

Everyone else, thanks for the comments, much appreciated!

Dustin, I think I'm going to do some mild cams first, but Nitrous is a definite possibility. I can't make up my mind between saving for a KB setup or just running nitrous.

 

your hp is definitely right there, and no I am not jealous lol.. i have a much better platform than you now...

you made about 15 more hp than me which makes sense, i didnt have a catback and some of your bolt ons, but you made 60 more tq? I would just like to know why..

 

because the car is a beast that was built on a Friday when all the workers were in a great mood.

 

yeah and I was in 20 degree higher weather with a lot more humidity, but still 60 tq is a lot.

 

Not going to waste my time.. Pretty much pointless, we should all bow to the '98 4v (still IMRC) powered, weak IRS drivetrain, many times wrecked, dawged stephen GeeTeeee!

I think I'll stick with my platform.

 

who cares if its IMRC, I delete them anyway.... :/ and weak IRS? lol upgraded bushings and half shafts = not weak...

and by wrecked you mean just front bumpers :>)

its ok, please goto the track so I can see how was 360 tq is.

edit: lol so I just read your sig... you dont even trap 100mph..?

 

IRS rear ends are weak, it's been proven over and over. If you can't read, that's not my problem. Just go through r3ds posts, I think he went through somewhere around 3-4 of them before trashing them and going with a SRA.

If I remember correctly your car had something like $3-4k in damage, correct? Last time I checked, paint + bumper, supports and labor do not equal anywhere near that amount.

Yet again, that reading thing is becoming even more difficult for you. The car made 340tq, that is Three Four Zero.

 

so you can run high 12's right?

that's about what 340 tq is in a mustang.

and it was actually ~5k

paint was over a grand, headlights, the panel that holds headlights and the fender got pinched in my door since the bumper moved it.. not to mention the 2 hours to check the frame was super expensive as well, nothing happened to front rails on the car, bags didnt deploy and the frame was as straight as it was from the factory.

 

So basically what you're saying is that your post above about the car being wrecked and it only being bumpers was bullshit.? Thank you for clearing that up.

The one and only time that I ran the 1/4 was just a month or so after I got the car. Wasn't shifting it properly and was running over 6500rpm before I shifted so yes, the trap speed was definitely low. I highly doubt that the car will run 12's but I have no idea, much lower 13's.. Definitely.

 

****** sweet Evan!!!! If you got that much gain with longtubes, i can't WAIT to put some on the Bullitt n see what kinda gains i get!!! Nice numbers fo' sho cousin!

 

You'll get the same gains.....you have the same motor.

 

dam dude those are some sweet numbers, especially for the mods. I am jealous of that torque, I need to get some 4.30's to get my 4v up and moving!

 

Same basic motor yeah... The bullitts have a different intake and twin bore throttle bodies though.

 

Yep, I was going to say the same thing.. In theory, depending on what headers/exhaust you go with it should be close, but your car should put up maybe 3 or 4 more HP with the bullitt intake.

 

Well as my car sits now, im puttin down 256rwhp and 297 ft/lbs torque. I sure as hell hope i get close to or a bit more gains as you. I'm thinkin of goin with BBK longtubes and o/r H Pipe.

 

The bullitt intake doesn't really begin to shine until you add boost, so with the BBK's they'll probably be pretty close. I also went with Hi-flow cats, so if you go with an o/r x you may see just slightly higher HP, but probably just a little less tq... Also depends on the dyno, like I said, this particular one is slightly under-rated.

 

Well it'll be a while before i am able to afford to run F/I of any kind. But... kinda off topic, and speaking of boost... i was on my way home this mornin from my girl's house, and happened to run up on an SRT-4 Dodge Caliber. I was quite surprised at just how strong those little ******* run. I underestimated him when we started to our lil run down the interstate. I only thought I'd need to drop to 4th. He immediately began pulling on me, so i hit 3rd, caught back up n walked him all the way to 140. I did pull away from him but not very quickly. Anyhow, yeah.

 

I believe your numbers to be accurate. I put down 256-299 on a dyno jet SAE corrected in mid summer through my auto with full bolt on's and that exhaust set up. With your car being a manual of course it will have less of a loss in power than a auto.

 

nice numbers bro! I have been debating on long tubes on my 4.6 stroker. I made 284 and 340 with the kit, and i am hoping that the tubes will help raise the torqe even more, so nice to see someone with good numbers from those.

 

longtubes will absolutely not help tq. hp yeah, they're worth 15-20 up top.

I did the LT's and gained 20hp and lost 1lb of tq. Our combos are similar, mine just has a taller deck.

 

Glad your pumped and all but honestly there is no way you got that much TQ off of LT's. My buddy with intake/exhaust and stg2 HiTechs made right over 300hp/tq. Thats right on for the mods he has. Saying you gained that much TQ is nearly impossible for that motor. It is simple 2v motor education that would tell you the number is not right.

Im not trying to rain on your parade but its just not believable from anybody who knows how the 4.6l 2v responds to mods.




Here are his listed engine mods and the numbers he made:

Hitech stage 2 cams, Mac Longtubes, VRS o/r x pipe, Bassani catback, CAI, Tb/Plenum
300/309 12.16 @ 112 1.60 short game

Heres the video of his runs at Ennis if you dont believe.

I think I have it figured out. 14.5:1 AF and all that timing, no wonder it reads high tq, he was pinging the **** out of it, the tq numbers are totally bogus. It was like a grenade going off in each cylinder every time, very high impulse but no carry. That's the kind of **** that blows motors. Man, get that tune off your car or find some way of proving to at least yourself that the AF isn't that lean and that I'm reading the graph wrong. You should be running 12.5-13:1 at WOT NA and not a penny more.

I don't want to **** on your parade but you ignore that warning at your own expense.
