The power is ok I guess... Should I do a compression test? I have a few very small leaks in my exhaust. 20% driveline loss on stock 280 would be 224 at the wheels. But thats a brand new car, I guess with age I should lose a bit of HP. But if something needs repair, that I could repair I would like to find that missing HP.
 
what is the deal with the AF informatin?

is the dotted line the first run and the solid line the second run.. or did they not have the sensor in the tailpipe.

solid line is flat line 11-1...second one looks dangerously lean if that indeed IS the AF trace

I saw cars with similar mods, making a bit more hp NA.

out of your expansive mod list, please tell me which ones you actually believe "make more HP"?

"Edelbrock high volume high flow job" = 0 HP

160 degree T stat = 6 hp

custom cold air = MINUS 12 HP due to hot air ingestion, especially on a dyno
the maf adapter has the filter too close to the maf and upsets the linear air flow thru the maf.

The LMS chip is probably 10-20HP but you have that hot air intake that negates 10 of those HP..
which is why with your HUGE mod list you net 9HP and 10ftlbs of torque

Since your dynoing the car..
Put the stock intake, maf and air box back on the car and go check the numbers.
I'll bet you'll get some of your lost HP back.

KustomizingKid is right, your HP is right about the stock mark 8 average

it was freezing outside look at the temp, i dont think it was getting hot air, but my intake setup may do someting to the linear whatever cuz it curves to go into the fender
 
14.79@94.69

this is the data from my dragstrip run last night.

says my car made 259@ flywheel

less 20% for drivetrain loss puts it right at 200RWHP.. right where a stock second gen mark 8 should be....stone stock, sct tuned by ME will out run your modded first gen.

just the ET differences between your car and my car should really REALLY make you want to re-evaluate your mod list.

you ran..what... 15.sumthin? (that's 3-4 car lengths slower than my turd)

im assuming third
Click to expand...

how did they prevent your car from downshifting on the dyno if they ran it in 3rd?

you shouldn't assume anything.

if they pulled the car in third, they had to get up to about 70MPH before they could "mat it" and not have it downshift.

if they made the pull in 2nd gear your numbers are actually about 20% less than what the dyno sheet says.

If they made the first pull in 3rd and had problems with it downshifting..then made the second pull in 2nd.. THERE is the 9HP difference..right there.

When providing data, or asking for feedback you simply cannot ASSUME anything.

bends before the maf do NOT promote linear air flow..sorry.

look..

you asked for feedback, I'm giving you that feedback.

you can "listen to someone who goes faster with less mods".. or you can continue to try and "justify" these BS mods.

my 95 {better comparison to your car) with LESS gear, no intake mods went nearly over a FULL SECOND faster than your car...
and my car had TWICE the mileage than your car.

I've been trying to get you to listen, but you would rather sink your money into "Internet HYPE" mods and GO SLOW..rather than have a stock air box and actually have a quick car.

You should take the references to LMS out of your sig file until you get your car to "run right"..
9 HP gain from an LMS chip is the equivelent of an "ANTI-LMS commercial".

seriously

he didn't gate shift it, look at the rev limits on the dynosheet. he put it in D... drove 1st and 2nd. Look at the different rev limits.... not sure if it was in 2nd or third but I do know that I clearly made gains on the chip.

The 209 whp with no tune, well that kinda sucks imo, but i dont have maf adapter intake as you stated, just wanted to correct that. It's not a hot air intake either.

The best gain clearly is the chip. No tune, im going to assume the exhaust did the most...
 
back when you first got this car.. I STRESSED the fact that you NEED a "baseline" Dyno pull or Dragstrip pass.

you ignored this very important information.

you waited until you did many things to the car before you took it to the track or bothered with a dyno pull.

you put alot of money into your car, and have this "idea" of how much HP you were expecting... and the DYNO gave you much less... as did the dragstrip.

Since you have NO baseline to judge your mods against, you have little or no good data to help evaluate your mods.. you've based ALL of them on what somone on the "internet said".. you even "SEARCHED".

Had you gotten a baseline.. and retested the car with your HOT AIR INTAKE..you quickly would have seen this mod actually hurt your cars performance.

If you had ANY data to support your "THEORY" you might have a leg to stand on.

HINT: ubercool long list of useless mods..does not make a fast car.

I think thats great for NA! look at the torque.... and my drag times sucked because I have crap tires. so good for your drag times.

sink my money into internet hype? what cuz i have a custom intake that i did myself? everything else is pretty standard

ubercool long list? i list the things ive done to keep track of stuff. So lets agree to disagree, ill put the stock airbox back, im making 220whp/ 229 whp chipped?

what else are you bitching about? besides my intake? what advice?
 
"You can expect in the 93-95 models a solid gain of 12-14 RWHP" well i got 9, -3 there might be some more variables that im missing 3-5 hp. This is on a stock mark btw im assuming. I am very satisfied what was promised, and dyno shows delivery. We also did two runs right in a row.
