I put down a whopping 165whp in 2nd gear. :lol:

Clearly, inaccurate. Got some good footage though. My tuner failed to show up. My fueling is still off (only made one pass of tuning on the street) and spark is stock. Still lots of power to be had.

[jrim]

Damn, never seen an engine shake like that :lol:

Cool:) Sucks that it wasn't right though, hope you didn;'t pay too much for that

[[ion] C2]

Ya, need to fill the trans mount with urethane. I bought the wrong stuff back when everything was apart, but I can get to it. Stock mounts allow for some movement.

[Midgear]

that supercharger sounds bad ass lol

that's 10.1 psi, and only 160 somethin horses? was the dyno broken? and what the hell is up with that 1st to 2nd shift? :lol:

[AbHeLlRaZoR]

Thumbs up, too bad your tuner didn't show up though.

[[ion] C2]

that's 10.1 psi, and only 160 somethin horses? was the dyno broken? and what the hell is up with that 1st to 2nd shift? :lol:

Ahahaha. Jan's dyno tends to read 80whp lower than another local Mustang dyno (and Mustang dynos read lower than Dynojets). It was comical. This is why it's notoriously known as the "heartbreaker" dyno. I was like "excuse me as I go shoot myself." :lol: Should be somewhere around 230-240whp.

Jan was driving.. liability, wouldn't let me drive. I was in the passenger seat monitoring the laptop and enabling the torque converter clutch and trying to lock the car into a certain gear. We couldn't get it to lock into 3rd and the temps of everything said it was a bad idea to do a 78-105 pull (IAT 170, coolant 220, etc. it was hot) He let off or something between shifts. Only saw a peak of 7 PSI there.

Went out on the street with my friend and saw 10. Also shocked him how quick it was. :p I tried to do a 0-60, still, way too cold to do, zero traction. Lost traction on the 1-2 shift every time too.

Thumbs up, too bad your tuner didn't show up though.
Ya, we'll be doing stuff on the street. I'll fuel tune tomorrow, and meet up with my tuner sometime next week. Next stop, the track. Or Monkey Wrench Racing's dyno (friend dyno'd at 380whp and lost to a stock SRT-4) LOL. So inconsistent...

[jrim]

Again, cool :coolio:

Hope you get your shit figured out soon bro, it's a shame to have all that power but not bein able to use it properly :P

[99alerogirl]

Wow that's awesome. Honestly never heard a supercharged engine full out like that... I need to get me one of those... haha.

[cherrington17]

Wow that's awesome. Honestly never heard a supercharged engine full out like that... I need to get me one of those... haha.

you have the 3400... save yourself the hassles and get a turbo.

look up blackjack's threads and/or video. you'll love those more.

[Nate's Alero]

3400 can be sc'ed only problem is the superchargers are hard as hell to come by, very expensive to get and then even more so to install, and wont put down the power like a turbo, chris is right, sc' is not the way to go on a 3400 but if you get a sc'ed 2.2 then you have potential, but i would go turbo, also more power/output than a sc...

[99alerogirl]

I was just saying that, I don't, nor am I going to anytime in the near future, have that kinda money haha. And I would go turbo anyways, but again... lack of funds :(


But ion's sounds mighty nice!

[[ion] C2]

Lol ya. This can work out for me. I can tell people it only put down 165whp, and then blow them away and make some money!

[[ion] C2]

If I use the conversion numbers from a guy on j-body's heartbreaker Mustang AWD dyno results, seems a bit better.

The dyno I was on reads like 14% lower than the local Mustang dyno which reads about 20% lower than a DynoJet, which would make my numbers 226whp. Assuming 18% drivetrain loss that's like 266bhp.

And then factoring in that it was done in 2nd gear instead of 3rd... that adds a bit more.

[Vinalero]

Damn that tuning must be WAY off lol

Will you finally tune it already? lol

[kwhauck]

screw dyno numbers, I want spring and summer to be here for track times!!!

[[ion] C2]

me too! i just wanted the video footage. lol

[Redog]

Sounds great. I though the engine was going to jump out of the bay :D

Get it tuned and have fun :p

[billytheman1188]

Nice:coolio: and ken.....thats a funny ass avatar. Cardinals ftw:ninja:

Thats funny Billy, I was gonna wait till the Cardinals kicked the Eagles ass before I said anything about his avatar.

Steelers All The Way!!!! Time To Get The Six Pack!!!!!

[TheEdgeofSanity]

lolz, so how'd the 1/4runs turn out?

[KenshinZero]

Wow that's awesome. Honestly never heard a supercharged engine full out like that... I need to get me one of those... haha.

there it goes, your hooked, there is no denying it now. lol

[[ion] C2]

lolz, so how'd the 1/4runs turn out?
it's based off the HP, said i'd run a 15.7 :lol: I ran a 14.8 with less than half the boost and mods.

[Vinalero]

Hell I ran 15.7 with only the supercharger kit and no other engine mod, Ion, you are wasting cash :lol:

[kwhauck]

i ran a 15.7 with just a muffler and CAI.....

Ok Chris..need to clarify.. my dyno does not 'read' 80 whp low. We had one car test down in Ohio on a newer model Mustang dyno @ 400awhp.. a week later on my dyno he tested @ 360awhp. So based on a sample of one..that's 10%.:p

Friday on the dyno you were only boosting at 7 Psig, heat soaked plenum.. IAT and ECT were high.. so it made what it made.

It does not at all surprise me that it was boosting higher on the street because ambient air temps outside on Friday evening were damn near zero F.

The only last unknown variable is actual engine RPM.. because of your auto trans, and lack of ignition pick up accessibility.. we had to roll-match the dyno with the torque converter supposedly locked via your tuning software.. if there was slippage in the trans.. the RPM the dyno was seeing could have been inaccurate.

Overall I'm not too surprised at 165 whp on a low compression 2.4L with the charger blowing hot air at 7Psig.. a typical 02 WRX puts down around 150awhp from a small stock turbo.. you're a bit up on one of those.. you could always find a stock WRX to race to see who wins?:yahoo:

[speed industry]

C2;421309']it's based off the HP, said i'd run a 15.7 :lol: I ran a 14.8 with less than half the boost and mods.

It's not based off the HP.. it's based off measured distance vs. time :)

I said 'based on the whp.. the 15.7 didn't surprise me'

[[ion] C2]

Fail. Maybe it was accurate.. when I was heatsoaked at the track a year and a half ago I ran a 16.0. When I went back and it was cold out, 14.8. :lol: But people with less done than me put down 200-210whp.. hell one guy put down 215whp with the stock s/c pulley :(

It definitely doesn't run 15.7 though, ha. By the time the tracks open I'll be on an intercooled MP62 setup though, just to make sure it's decently quick. :)

[rowdygls]

I think you'll pull a higher number with some good tuning, but it seems low for a starting point for the work you have done. I started at a similar boring base number but after tuning ended at about 200 but on a different motor and s/c.

[Vinalero]

Anyone can Explain to me why in the kit they place the IAT INSIDE THE DAMN SUPERCHARGER??!

Could they have placed it on the air intake tube? Does it really matter that much?

[[ion] C2]

Um you want the IAT sensor to read the actual air temperature that's entering the engine. Relocating the sensor doesn't change the temperature of the air that goes in, and with an inaccurate reading things will be unsafe.

[Beholder88]

As I recall, the IAT is supposed to be as close the the TB as possible, right?

[AleroB888]

IAT sensor mounted in the intake manifold works best, in my opinion ( for the 3400 V6). With a remote mount intercooler, and scoop directing air to the IM, especially, it is better to track IAT close to what actually goes into the LIM.

[Beholder88]

I've seen IAT's directly mounted to the Plenum, right after the TB, does that make sense?

[Vinalero]

Well, IMO the IAT could be really closer to the TB.

The way this kit is made, of course the Intake manifold is hot as hell. Hes right behind the rad, and the way the Alero Front end is made, not much air can enter directly near it.

I guess later I should make some hood scoop on the very beginning of the hood.

[Spilner521]

^^I know what you're thinking, but it doesn't work that way. It's an Intake Air Temperature sensor, not a Manifold Surface Temperature sensor. Does the hot surface of the manifold affect the sensor? Maybe a little, but I don't think it would be a measureable amount since the actual sensor itself protrudes into the manifold into the air.

Ideally you want that sensor as close to the intake ports as you can get so that it gives the most accurate reading of the air entering the cylinders.

[[ion] C2]

We had one car test down in Ohio on a newer model Mustang dyno @ 400awhp.. a week later on my dyno he tested @ 360awhp. So based on a sample of one..that's 10%.:p

So if we add 10% to match that Mustang dyno, and then 14% to get it up to what a DynoJet would say, it'd be 206whp. lol

Yeah I understand your point Spliner.

I was just telling that a hot manifold probly warms the air inside of it.

And since alero's doesnt have a top front opening below the hood, the intake isnt cooled down by outside air.

That would also answer the fact that since winter started, it seems like my supercharger is boosting a lot more than before.

[Spilner521]

Again, it might affect the air temperature a little, but the air is moving so fast through the manifold, especially with boost, that it would have little to no measureable difference.

The cold outside air would cause that, not just a colder manifold.

[speed industry]

C2;422255']So if we add 10% to match that Mustang dyno, and then 14% to get it up to what a DynoJet would say, it'd be 206whp. lol

LOL, I wish it was that easy. About 4 years ago someone took an NSX to my dyno (before I owned it), a local dynojet and a local dynapack all in one day. The results are somewhere on NSXprime.com if you want to search.
:yahoo: :ninja:

[rowdygls]

Is spark tuning another word for adjusting the timing ??

[[ion] C2]

Yep. Timing of the spark..

[Spilner521]

AKA Ignition timing

[rowdygls]

Thank you...I figured so much but wasn't sure. I know once we started playing with my timings the car started coming alive. Something to look forward to Chris.

Clyde (the guy who was at the dyno who taped up your electrical outlet) put down 226whp with the stock tune and injectors... lol.. ridiculous. A lot of these guys dyno 205-215whp with the stock pulley. Which is why I was highly doubting Speed Industry's dyno reading.

[Beholder88]

I've seen that video before, there is another Cavalier or sunfire somewhere on there, or maybe it's on streetfire, that put down 500+ HP. It had the 2.4, but I don't know what the SC was, or other mods. Anyone seen this?

[-Alero-]

sweet dude thousands spent on 40 whp....hey it could be worse right you could have a manual transmission
