Domestic Truck in Champaign, Big Mouth, Small Truck Options

[TotalEclipse97]

This guy i see at work all the time rants and raves about being a "street racer". He's in his late 20's early 30's. I asked him what he ran. He proceeded to glorify his Z71 Chevy that was putting down 320hp to the wheels. I didn't want to make fun of him ( even though i should have ) so i asked him what/who he raced. "rice burners" he said...."little imports with big tips"... he went on (again) to tell me about smoking some guy in a ford v8 triton. I think this guy needs to race the right people...so if anyone's up for some fun here's the truck's description


Z71 Chevy XT
All-Wheel Drive
454 with Headers
Custom Y-Pipe
Stock Muffler System (no glass paks or anything fancy)
2.25-2.50 exhaust (dual tips)
Green on Silver
Tinted Windows (with little stickers)
Nothing flashy
K&N Filter
No lift kit,custom rims or anything just stock

and he said something about his throttle body but whatever. 320 to the wheels


have fun guys

yummy.

I think I'd be more worried if he was driving a diesel.... He might have 320 to the wheels, but he's also got 6000 pounds to lug around.... talk about a fatass...

my old boss has a new dodge cummings and a new deramax. Both have chips and exhaust. he's putting aluminum heads and bigger injectors in the deramax. both are pretty damn quick for being full size trucks.

I'd put $50 on your car over his.

[TotalEclipse97]

thanks for the support but remember i'm only running the 14b cause i have no cash

[ncgalant]

rewire your fuel pump, do some logging runs, and turn up the boost and you'll beat him bad. a 14b will make you 250whp on your stock everything without that much work. I'll do some runs with you sometime if you want.

[TotalEclipse97]

how do i rewire it? it a walbro 255 high pressure. also i've been getting,what seems like, fuel cut if i'm gunning it. it happened to me in 4th and it happened to Travis in 3rd. We turned down the boost to 13-15psi but i'm thinking i need bigger 'jectors. did you run 450's on the galant?

[ncgalant]

When are you free to log that bitch? We can do some MAS hacking if nothing else. 16psi's probably about all we can get from a 14b, but will feel very nice properly leaned out.

Rewiring fuel pump on a 2G:

Fuel cut is more prevalent in cold weather. Nevertheless, its strange for your 2G MAS to be fuel cutting at 15 psi on a 14b. There are guys out there running 16g's on 2G MAS and stock injectors at higher boost pressures w/o fuel cut. If you have been seeing a lot of knock your ECU may have lowered your "octane" value low enough that it is allowing less air before fuel cut.

Otherwise, you might want to crack open that ECU and check for leaky caps. My old fwd used to fuel cut like a bitch and it turned out to be from leaky caps on the ECU.

That's a beautiful 2G, btw!

I don't think it was fuel cut as far as the ECU pulling time due to too much air flow. I'd bet on a knock situation first personally as I can't see the 2.4/14B set-up pushing really being able to flow enough air to push a 2G MAF.

More of a 'not enough fuel' thing. I'm wondering if the 2.4 is able to swallow more fuel than the 450's are able to provide at 16psi on the 14B.

Not much other reason for knock on his set-up with a 14B. I'd feel better if it was being logged though when the symptoms were occurring to watch the ECU yank time via the logger though.

[natedogg]

Ahh, so its not really fuel cut then. It may very well be a lean condition considering the volume increase of the 2.4.

I ran up to 15psi on 450s with my frank 3 and my stock galant ECU. That was with my horribly hacked MAS though. The logger will really tell all.

Nobody has mentioned it yet, but it could be spark blowout too. I've felt that and its very much like fuel cut.

If you want I can meet you in Bloomington some night with my logger. PM me, or give me a call. 208 7633

make sure it's not compressor surge either. From the things I've read a 2.4 can turn a 14b right out of it's bearings on exhaust volume alone. Depending on the exact problem the turbo may just be too small.

[TotalEclipse97]

I havn't had the (what felt like fuel cut) lean condition problem since we lowered to psi to 13-15...but i havn't floored the junk out of it either....i guess i'm kinda scared of what kind damage i'd be doing to my car.

Hey does any know where i could find a bigger smic. i saw acouple online that a guy took 2 stock ones and welded 'em together and rigged it up and he said it was performing almost as well as a fmic. any suggestions?

That seems a little familiar to me too! Pull like a beast to 4k and then fall on its face...

I understand pride. I have more than most. Therefor I understand being proud of your ride. But IF you talk like it is said, you are in need of an education. I'm not saying you are not an experienced street racer, nor do I doubt you in any specific way. However, you do need to realize the performance potential of this particular type of car. I'll never say that you should fear a fart-canned Civic in your Z71, but a lot of DSMs will hand you your ass in a Vette. Been there, done that. Be proud, because without pride there is no drive to compete. But don't be closed-minded and ignorant. You'll just lose. I'm truly not trying to be negative or instigate, more like a heads-up.

Welcome to the site. You should check out some races sometime! You ever seen a daily driven import spin it's tires past 100mph? It's a good time.

[natedogg]

Actually, I think the more people who don't know the potential of DSM's, the better. The way it used to be. Some old 80's Camaro driver would take one look at my car and put in the same category as a fart-piped the car that we shall not name Civic until I handed him his ass.

[The Iron Goat]

Hehehe, there's no greater feeling then making one of those guys drop his jaw. "How'd that little rice POS beat my 'Maro?" "Damn, that's a quick little car!" It's the funniest expression I see on other drivers.
