Dynoed my GN today

[TylerDurden]

i would think that dyno graph looks a bit off, first question

how was the pull done? what gear did you do it in, did YOU gas it, or did the dyno guy? reason i ask, is i know when mine was pulled, it was done in 3rd gear...took the car up to 70 mph or so, that way you get no kick down and the 1:1 gear ratio is somewhat crutial in getting accurate numbers....unless there is some sort of setting for different gear ratios on the dyno itself...also, i always though our engines even stock should have a relatively flat TQ curve onced peaked, i know my torque didnt drop off untill 5400 rpm (stock motor, new valve springs) if you have some miles on your car, you may want to get fresh springs before you do some of the other "non power adding" mods. ie inlet bell, suspension stuff

yet another reason for me to get them, I can feel my power drop off around 4000-4500 rpm when they should be climbing.

A cheap $40 will fix it!

I dynoed mine two weeks ago and turned the boost up to 21 psi running 112 octane fuel and turned 328 HP and 460 ft/lbs.

 

[turbocody]

those are some respectable #'s ws6formula, i dynoed my car back in october in street trim it did 281HP and 414Torque at 3600. in race trim it did 316HP and 456Torque, this was with stock turbo and Injectors. if you get some good gas and a race chip you can crank that boost up and easily see 400Torque. and both my pulls was at 19-20psi.

we need to all keep in touch so when its nice out we can all get together and cruize the spots or do dyno pulls together and show the v8 guys a thing or 2 ..

Im not bringing out nothing too hype this year just a ol V6-PIGUP

RED just you keep that ole PIGUP truck away from my GN, I don't need you hurting my feelings with that transplanted motor!

I got enough to worry about with Bobby's cars kicking my ass!

We Va boys should make a road trip to Andersons in MD. he's got his dyno up and running now.

I have the oversized snubber in my 86, no problems, about the same mods as yours. I am however, looking for a 1 piece downpipe, (with elbow included) for my GN. Anyone know of somone selling a good used unit? I priced new SS at around $414. I'll pay it if I have to, but would rather save a few bucks buying a good used one if possible. Thanks, Ken.

It was 3rd gear, T/C unlocked, for the reason you stated. I disconnected the TV cable also, dont know if that hurt/helped/made no diff at all. I was thinking about doing valve springs actually, I have 78K on the car. What springs are good, I have seen some posts on using LT1 springs. On stock cam?

I can get you springs local and good price

my buddys gn had 60,000 miles on it and picked up 4 mph in the 1/4 just switching springs ..results may vary

I dont want none of that gn of yours nearing... not with the el atleast

then again my ttype wont want none of the other car you got

Sounds like fun .. but I would rather go to MIR for a track rental. I have a new goal now .. bobby might have put the 130 on a stock cam on the back burner ...but I am gonna go for it now ... think I got a turbo up to the task now. Just gonna have to see if Eric

(Turbo Tweak) is up for the chip tuning

Yep, a track rental would be fun

I imagine that turbo does have 130 in it, especially if Red sets the boost for you

When Is your car going to be ready?

If it isn't too crappy out I hope to get the headers and new exh on this weekend. MAYBE the other converter too.

I've got a Line on a 67Q trim .

 

[NEARING]

I don't know how long Bobby is going to keep that on the back burner so don't wait too long!

 

[REDS HOT AIR]

wonder what it would cost us to fly Eric out to a track rental to chip tune for us chip guys

With that turbo, some magic smoke put in the chip by Eric (turbotweak.com), a tankful of c 16 and a disconnected wastegate .....I think its possible

NO FEAR .. lmao .. Car should be straight by the end of the month. Just have to see how busy Eric is. Tranny going in next week.
