i went to dyno test my 86gxl with about 160000 miles and the graph was all messed up going up and down after like 3500 rpm and at like 6000rpm it skips a little and the max hp was 144and the other one the was 133.3hp and 114.7torque and what i want to know why was the graph all messed up because it is suppose to go strait up and they told me it might be the plugs or wires but they are not that old

 

or is there a better section to post this in

 

Can you post the sheet? That would help us a lot more.

 

You probally have alot of hesitaiton from a number of things, but you also need to BUST OUT THE GRAPH for us please.

 

right now i don't have a scanner but i will see if my friend can post it or something

 

Probably got the 3800rpm hesitation going

 

that was i was thinking but can it go all the way up to like 7000rpm and mess up every thing if it was the 3800rpm hesitation

 

If that dyno was right 144 rwhp is rather impressive for a stock 86. Is it stock?

my mods are racing beay headers road race,tb mod,no a/c,msd8.5 wires,intake withe cold air box,hks exhaust,no cats,and no acv just have the block off plate form racing beat that is all i can remember right now i will ask the place if they can email me the graph

 

and ACT street/strip clutch

 

i have the graph on my computer but i don't know what to open it with

 

or can i email them to some body

 

Yeah. Send it to dahmsj@rvvs.com and Ill put it on my webserver. It should be pretty easy to find out whats causing the hesitation based on rpms.

Here is the dyno sheets. I only put on 2 runs, the other 2 were pretty useless.

 

that is in 4th gear so you might be able to figure out what rpm the power is at

Looks like spark is a problem. A CDI may help smooth that out.

 

Or worsen It.

 

got old plugs in there, plus a good thing to do before you go to the dyno is make sure your car is in tip top condition, new plugs, wires, oil change, Tps, idle, ect, but a dyno is also a way to find out problems, not the best and pretty expensive too...

 

the plugs are not that old and also the wires and i have messed with the idle

 

In all honesty, you only have a slight ignition break up there. Buy a new set of plug wires and ALWAYS go to the dyno with a BRAND NEW SET OF PLUGS! I don't care if your plugs are a week old, change them.

My ignition break up was way worse than yours! See the dyno run on my webpage below.

On my first couple runs it was bad. My plugs were about 1000 miles old when made the first couple runs. We changed the plugs on the dyno with new ones and I picked up 2 RWHP.

Since then I've replaced the stock NGK plug wires with Magnacore wires and installed 2 MSD Blaster coils with an MSD 6A. The car is so much smoother now!

 

I wanna see a TQ curve (actually I'd rather see a flatline )...do you have one???

 

how do you post the dyno because i have more graphs

 

I was bored... so i scribbled on it
