why are my dyno numbers so low???

I got 280 hp and 305 tq... I have the zz409 cam, thinner head gaskets, flowmaster muffler, bosh plainum plugs, msd ignition, moroso intake, tire pressure was around 32, egr remove, air removed, custom tune at hitech motorsports, I htough I shoul dhae been around 300..
it was on a dyno jet if that matters?
also the tech said my oil pressure was low, at idle it is a little over teh 0 and wt it is under teh 40...is my car messed up??

All this counts for diddly squat. I might say you would get 10 RWHP out of this. So since it is a 94 you started with 220-225 RWHP bone stock. So to say you got an additional 60 RWHP out of that above mentioned stuff and that cam, I would say you should be happy.

You oil pressure should have been around 15-20 PSI and 40-60 WOT.

You gotta be ****tin me! you actually think that since his car is a 94 that it came with 220-225rwhp? This is not a mustang. I think that any stock 6spd that dyno's under 250rwhp is running like crap.

I don't think you're too far off considering the mods you have. You will pick up quite a few ponies with a set of headers and a decent cat-back system. What are the specs on that cam? I don't see any reason why you can't see well over 300 rwph with the mods I listed above.

Well, I didnt realize it was a M6. Thats my fault for not reading his sig close enough.

So you really think that a 94 LT1 M6 BONE stock dyno's OVER 250RWHP if not it runs like crap

96-97 LT1 A4- Dyno 230-235 RWHP Stock
94-95 LT1 A4- Dyno 225-230 RWHP Stock

GM calls the engine for the 94-95 LT1 275 HP
GM calls the engine for the 96-97 LT1 285 HP

Subtract your % loss thru the drivetrain for an A4 that is what you get.

Now an M6 does not loos as much of a % thru the drivetrain.

A 96-97 LT1 M6 will dyno 245-250 RWHP bone stock. With a94-95 M6 around 240-245 RWHP bone stock.

Sure if you take numbers from a magazine thats what you would get, but if you look at real dyno numbers you will see otherwise. BTW, if you didn't notice this guys car is a 6spd, so you just contradicted yourself.

Hey D*ckface. I said I did not realize it was an M6. I glanced up at the sig as I started to write a reply and the first thing I saw was A4, which he does have in his sig as another car.

Im getting real sick of people like you jumping on others that try to lend there own opinion.

What you need to do is make comments for your own piece of crap. Your car runs like crap and the drivers even worse. I would be shamed all over town if I had driving skills like yours.

I dont have the pantients for dumbasses like you

Hey why don't you stfu. I didn't not see that you didn't notice the guy had an m6. You try and launch a 306 cammed car from idle with stock gears! Car didn't even start going until i hit 45mph.

i pulled a 257rwhp with a K&N CAI and hooker catback

so i'd say A4 1995 z28's came with roughly 240-250rwhp stock


btw, can you feel the love in here? i sure can

Gotta love the drama.

Doesn't sound as if it's too low....CAI and catback I dyno'd 260ish through an A4.

OK I'll try to get this in before it gets locked....

Do a search for what good 1st mods are....CAI, Cutout and headers will give you a boatload, and then you should be near 300 HP....

Most of the stuff you listed isn't much for HP. So I recommend going with the above, and do a search for free mods. Things like the TB bypass, TB airfoil, LT4 KM (with headers and cam) will give you a few each, which adds up.

I hope the bickering can stop soon.
