LSA swapped Colorado vs. my Cobra

[520Terminator]

I have a friend who is a tuner here locally, and was working on an LSA swapped Colorado for a shop. I met him at the dyno to check it out and see what it made, on the way out, the owner asked if I wanted to run him, even though it wasn't entirely a fair run. I said sure just for the hell of it. I tried to heat up the tires a little bit, but it wheel hops bad (need to get the FTBR kit ASAP) so we wen't from a 20 roll on cold tires. Still spun bad and had to pedal it through first, and I need to work on my 2-3 shift lol. The little truck hung pretty well until I got traction haha.

Colorado :
GM LSA crate motor
Lingenfelter 650HP kit
shorty headers and full exhaust
13PSI
4L65E
9" rear
401/583 on a Mustang Dyno 100 octane

Low numbers due to a stingy dyno, combined with restrictive exhaust

Cobra:
Mods in sig,
335 Toyo RA1 @ 20 psi

Cant see shit.

 

[520Terminator]

as in too dark? Or can't see the video?

 

[520Terminator]

i think I fixed it

 

[TBCobra]

You fixed it. That truck was quiet as hell for full exhaust. Looked like he wasnt even racing. lol

 

[520Terminator]

I meant full exhaust as in cats, mufflers, tails etc. I'ts not very quiet, but my Cobra is obnoxiously loud.

 

[520Terminator]

It would really benefit from a free flowing exhaust setup. It has a small y-pipe that fits the Colorado. The guy was disappointed with the numbers, but we both told him, cam swap, better exhaust, and ditch the stock air-box.

Same shop is building an older f-150 (97-03) with a Raptor 6.2 and a 2.9 Whipple. Should be fun lol. I will get pictures and vids of that when when it's up and running

I saw this same truck over on Performance truck.com and he was needing help tuning it.

 

[520Terminator]

Yeah,ECU was all jacked up I believe. Had to get a dealership reflash before it would accept a tune. I went down and tried to help him fix it one night.

 

[Shhhh]

Thats a neat setup!

Nice truck, but 401hp?

I'll be captain obvious and say that something is definitely wrong. An LSA should put down a lot more hp, especially with the mods listed.

Thats what i was thinking.....:shrug:

It's got a stock thermostat in it, so it was like 220* on the dyno, restrictive exhaust and a stock Colorado air box so it was breathing through a straw, and it's on a Mustang dyno, and one that even for a Mustang, is known for being stingy. Both tuners tried hard to get the numbers up. Also remember, it's through a 4l65e, transfer case, built 9" and large off-road tires. Adding all that up, it really doesn't seem too far off.

Love the cobra. Sounds awesome!

 

[mebetter]

Cobra rolled out nicely and sounded great!

 

[520Terminator]

Thanks!

yeah that stuff does add up but man.... 401rwhp? For comparison a guy on camaro5 dynoed a 650HP package on a 6speed ZL1....it dynoed 570rwhp and 630rwtq...so pretty much on par with a 650 package and this was on BONE STOCK EXHAUST setup. Loosing 200rwhp or so seems like a lot.
