my TPI v8 gets 15MPG on stock tune.
my MPFI v6 gets 23MPG on stock tune.

i reeeaaallly want to get a holey commander for my GTA. then i could probably up that to 18-20 MPG. (plus run another tune for mad power) Cool

Why so low on that TPI? You run a high fuel pressure?

heh, u said u think i get 20-26 mpg? try 15 in town.. when i first bought this, it got 7.. pretty sad for a v6

i think i should just fix the knocking crap, sell it for like a grand and buy a decent runnable one

my TPI gets 15 MPG because i have headers and catback, and i drive it like i have headers and catback Very Happy

i could probably squeeze 16-17MPG if i drove easy.

my MPFI i drove the HELL out of, i mean like, hard acceleration most of the time, and i still get 23 city. hwy was like 30.

i just have a feeling this car is gonna give me nothing but problems in the future, and besides, my moms trying to sell her 84 z28 camaro 305.. that wouldnt be bad i guess cause at least with a 305 i would have more options toward performance, i just dont understand how my v6 is faster than hers. oh well shouldnt be that hard too beef it up, and parts will be much easier to find since i see them pretty much everywhere.. and thanks for the sites ppl. i appreciate it since i know now im not going too do anything too beef this crap tiny motor up. oh and i broke the tranny mount, crawled under, pulled the cross-member off, took out 1 bolt to the mount, tried to take the other one, stripped the head, now i cant get it out so i had to bungee cord the damn tranny down.. lol Rolling Eyes

Danked - If you actually manage to get your $200 back out of it, I will be suprised. You're not getting 1K out of it unless you're the con-man of the year (no offense).

Your mom's car will almost certainly be an LG4, 140-ish HP, it's a joke, but it's a V8. Pretty much everything on that engine is a bottleneck, but you'll have better luck with it than the 2.8 IMO. Plus you might learn something along the way.

For your tranny mount, roll down to whatever auto store you have around there, and invest in pair of vice grips. If your dad has the machine shop you claim, he probably already has a pair. If that doesn't work, try and run it back in. What was wrong with the old tranny mounts anyway?

Tony - Headers and a catback will improve your mileage. What made you think a free exhaust would make it worse? Shocked

bungee chord.....

remind me never to let you work on my car Wink

and the reason your 3.1 was faster then your moms 84 305 is.....
1984 Z28 LG4 V8 8.6:1 5.0 (305) 150@4000 240@2400 4bbl

1991 RS LH0 V6 8.5:1 3.1 (191) 140@4400 185@3600 MFI

so provided your v6 was at one time in decent tune, it is likley your moms z28 is suffering from wear to the point where she has lost 10HP.. probably compression loss due to blowby, valve seals, head gasket.. etc.. a great many things. could be her carb is out of tune. or her exhaust is too restrictive (original cat and muffler?) etc...

one thing is for sure. we know it was not your muffler giving you extra HP Laughing

heh your funny tony, and yes.. i have like 10 pairs of vice grips myself... Confused

anyways.. i cant get the bolt out because i already tried that, i had it jacked up and used a grinder to try and make a new bolt head, and sorta just shaved the whole bolt head off................ Sad

How much is sticking out? If there's enough to get a bite on, you can try heating it and using the vice grips again. Some guys claim you can actually weld a bit of metal on to give yourself more leverage.

Tony would know more than I would, I hear he's the master at stripping bolts. Very Happy

Danked · Posted: Fri May 19, 2006 7:39 pm Post subject:

maybe 1/6th of an inch is still stick out, and yes my moms still has stock exhaust but no CAT heh.. just like me Very Happy

That bolt should be around 40 ft. lbs., so it's not as bad as it could be. Do you have any left-spinning drill bits? If you do, you can try and drill STRAIGHT down the center of the bolt and see if you can back it out that way.

Holy sh**! Shocked

You drive across the state of Kansas with your hood up, or what?

dude, for real. a cold air intake needs to be positioned to get to some cold air. Laughing

check out my raging 2.8L shizzle

shazam. there is also a hole cut in the "battery tray" thing that used to house the stock air box.

Correct me if I'm wrong here, but on a EFI car, the amount of air is measured by the MAF/MAP/ect. and proper fuel is added. The fact that the engine is doing less work on the exhaust cycle has nothing to do with it.
