bored out

CAI (C&L Racer)
93 Octane Race tune (Bamachips)
Shorty Headers (Steeda / BBk)
O/R H pipe (Pypes)

Do you think this set up should crack 300 HP?

i'd do pulleys too and probably a throttle body although they dont help much. its pretty hard ( i tihnk) to get 300 RWHP outta bolt ons, i mean theres some i dont know about but the basics probably wont from what I HAVE read

GRAYPNY

To get 300 RWHP on a N/A motor it will probably take the following:

Under drive pullies
Charge motion delete plates
Long Tubes (not shorty headers)
Cold air kit with good tune

MAYBE?

I was at 296 with JLT intake, offroad H pipe, mufflers, and custom tune. I got to 303 with those same mods + pulleys and delete plates.

boduke0220

explain the "plates" thing to me?

tom281

There are butterfly valves in the intake ports; the delete plates replace the factory plates which contain those butterflys- therefore deleting the butterflys and opening it up for more air/flow = more power up high.

Here's a bunch of info, I just searched it for you quickly:

I am at 300 rwhp 312 rwtq with a JLT2, Predator with DTP tune and Magnaflow axle backs.

I'm currently at 293 HP, with Steeda 90mm CAI, Bamachip's 93 race tune, and Steeda UDP's..So I'm quite sure, that with either CMCV delete plates, and or O/R mid pipe ? should just be enough, to break the 300 RWHP mark..

tom281

Wow man you musta gotten one of those factory freaks... 300/312 with basically just an intake and tune?

Yeah that's a heck of a gain with those simple bolt-ons.

More like a freak dyno. It happens

In socal...who tuned your car?

FWIW, I am at a little over 300. My power enhancing mods are intake, dyno tune, u/d pullies, and a x-pipe w/high flow cats. I also have other stuff but that's what got me there.

hi all,

Here's my plan:

steeda elbow and intake
SCT TUNE
FRPP shorty headers
FRPP x-pipe
FRPP GTA axleback

i hope this will get me to 295-300 rwhp...

05YellowGT

I got 311 RWHP with the mods in my sig , minus the C&L trueflow inlet tube and the FRPP X-Pipe which were added later ...

The tune is from DTP racing (bought over the internet - that is who was originally doing the JLT tunes) and was verified by Steve at Power Train Dynamics in Huntington Beach. I had scheduled dyno time for him to do a custom tune, but he said the tune looked pretty **** good. He said he could charge me for more dyno time and probably get a little more power, but recommended keeping as is until I did some other mods. Keep in mind that he only does dyno work, does not sell any parts, and is well known for his dyno tuning.

He made 3 runs and they all were right there within +/- 2 of each other. He also checked the tune at different rpms, on/off throttle, etc. to make sure everything was safe/good.

Freak or not I'll take it. I haven't been to a drag strip to verify with any times, but hope to some day when I get a chance.

I added UDP's a short time ago and once I install a Spydershaft I'm going to get a dyno tune and I think that will get me at 300rwhp.

I'm at 315 whp and 329 trq with just a JLT II, American Racing LT headers with a catted H pipe and an 87oct tune from Tillman Speed. My local performance shop claims I have the record on their dyno for horsepower on 87oct. Ok sorry 328.9 trq. I saw this after attaching the dyno sheet.

superman112

Nice numbers Pedkac!!.. I should be setting up some dyno time with Tillman speed by late Aug. I hope!!

Lowe!

I've dyno'd 300rwhp a couple of times now, with mods in sig. An alternative to the LT headers w/ catted H-pipe, is an O/R midpipe. There are 2 other Stangs with the same mods as me, other than I have catted LTs, they have O/R mid-pipes w/ stock manifolds, and we were all just over 300 rwhp on the same day.

My tune is still not quite right. I consistantly around 11.5:1 on my A/F ratio. And who knows how much spark advance could be left. All of my 300rwhp runs the temps were over 85* and humidity over 65% (although, these are SAE corrected #s).

I'm at 303 RWHP and 314 RWTQ with C&L Racer intake, Brenspeed 93 Oct SCTII tune and Steeda UPDs with my manual trans on a DynoJet.

Or, 281 WRHP and 297 RWTQ on a Mustang Dyno with everything the same except this was before the UDPs.

Stock baseline on the Mustang Dyno was 261 RWHP and 276 WRTQ.
