So I finally dynoed my car today just wanted to post them up here and check some things out. I made 206hp 203torq at 7psi spiked to 9psi and it made power all the way to 6k. I ran 15psi spike to 18psi I made 262hp 317torq but the car stopped making power at 4500rpm it just flat lined and lost power after 5500. The guy said that my plugs are gapped to big. There at 35 he said put them at 25. I'm running br7es plugs. I'll post a link to the graph.

 

Here's the 7psi

I forgot to post the mods I have.

 

Dad njv head with ss valves and HD springs

Not a port job but polished it myself.

 

Stock manifold ported myself all 4 holes and the exist hole to the turbo is huge also with a t3 adapter. I have a 17c syclone turbo that is also ported out.

 

3in downpipe and 3in exhaust all the way back

Mod Stock intercooler 2.25in hole in and out and 2.25 ic pipes

Gm maf translater.

Stock 86 ecu

Yea it pulls good. My question is should I gap the plugs down like the tuner said?He said my car should be putting down 280 290hp with 15psi not 260. I was thinking that's a lot of power I was lucky with 260 at 15psi. Most people I see here has more mods then me and only 260hp with 20psi with the 16g 17c turbo. Did I just get lucky?

Thanks for all the replys.

Unless your blowing the spark out (miss fire) while boosting, theres no reason to regap.

 

I agree with Harry, those are good numbers for the mods. What was the A/F during the pull? If its a little rich (safe) youll give up a couple HP. If your detonating the computer will pull ignition timing and youll lose somemore HP. Id leave it where its at.

 

Good job

I've had it on 20psi plenty of times just didn't run it on the dyno cause of what the guy told me about the plug gap. Car moves on 20psi but has the same problem when I hit 5k rpm that's it no more power. It's that how these turbos are out of stream at that rpm or is it a spark gap problem?

gap will cause a miss. I missed that your on MAFT. TD06 turbine should be plenty. Looks laggy on the graph. Is it that slow to spool on the street? Edited by Funky Phil

It does spool a Lil slow in my option on the street I hit 15psi at around 3200rpm but the car won't start to pull hard till after 3500. Then the boost will spike to like 18psi or so at 4k rpm and drop back down to 15psi at 5k rpms.

 

I'll be home in a couple hrs so I'll post the pic of the boost pressure,rpm,hp,torque, afr all that good stuff.

So I just drove the car and it doesn't match the graph right my boost does hit 15psi at around 3200 not 3800 like the graph shows.

Also the graph show my afr at 13 at 4k rpm during the boost spike at 18psi. That's not right. My wideband hits 10.8-11.3 immediately once I start making boost. So which gauges are correct?

 

Thanks for all the replays

Yea I know that was a good run. But my question is why is my power falling off after 4500rpm is that how it suppose to be or can I fixed something here? My last setup felt faster. Only difference was the maf was a blow threw instead of before the turbo like it is now. Also I had a custom made log manifold with a t3 flange and external wastegate dumping to the floor. My butt dyno said it was faster and pulled to 5500rpm but no dyno to know for sure. I just know I shifted my old set after 5500rpm and with this set up I shift before 5500rpm.
