TD06 20G Dyno With Pics

[bardabe]

Alright fellas, after street tuning my DSM for about three weeks or so my low throttle settings I hit the dyno for my WOT tuning. My Mod's are as follows:
Mod's are as follows:

TD06 20G Clipped 15* + Port and Polished
Ported Manifold
Tial 40mm WG
3" Turbo back exhaust
Wally 255
FIC 650cc Injectors
Evo 9 FMIC
Greddy Type S BOV
Manual Boost Controler set at 20PSI

Fuel Management is SAFC alone

The First graph is how the car went in, and the last graph is how the car went out of the Dyno. I was running a .030 Gap on NGK BP7ES spark plugs and NGK wires. However the AFR was off the charts (supper rich) and well was blowing out the spark. My tuner set the spark for .020 He said "when you are running that much boost you need to close the gap." Isn't .020 too little of a gap? reason i ask is because after so much tuning i got a nice 11:1 AFR however my Graph isn't smooth, do you guys think It's something with the spark perhaps the gap being too close? I'll post some Datalog numbers in a bit here is the Dyno Graph.

This is the Data Log of the 12th Dyno Pull in the One Hour of TUning

And this is the Data Log after i got home and let the car sit for about 5 hours. however in this run it was raining outside so it was impossible to get ANY traction in 3rd gear after boost hit

please excuse my grammar / spelling I'm working on it.

I'll do some more data logs after i get my boost leak fixed (idle control screw) and some better couplers + T-bolt clamps. so hopefully this weekend I'll have a better log for you guys to see.

My To Do List as of today:

Re-Gap plus to .026
Better couplers + T-bolt clamps
Fix boost leak on Idle screw

Data Log it.

While those are good things to do... I don't think you will see gains suggested as capable from 650's. I still believe you are near the norm for your setup. Perhaps as much as 10-15% more can be fished out.

I'm a sad sad sad little man, couldn't get my couplers this weekend, SOOooo I am still running on the stock balloons but i got the boost leak fixed and the spark plugs gapped properly. Made a world of a difference, I'm did a log on my way from work yesterday and yeah I'm getting 17* of timing by red line car breaks loose even on 3rd gear... shit is kinda scary, torque steer doing 75mph! so now I'm positive i must be in the mid 300's either way that should / is fixed. Now I'm concerned my alternator is getting heat soaked, anyone down for a group buy on custom aluminum heat shields??? and slim fans???

P.S. I work at an aluminum tig welding place so im sure we can make them cheap!!!

Lots of misinformation in this thread. If your are making 300+whp, then your spark plug gap should not be anywhere near .030, it should be more like .025. Period.

No. over 25 psi with the factory gap with NGK 7s here. Many, many do the same.

650cc injectors will get around 375whp on PUMP gas with stock fuel pressure before you get over 100% duty. 650cc injectors will hit 400whp when using race gas because of the leaner burn and different specific gravity of the fuel. Trying to run a rich a/f ratio and 650cc injectors at 400whp will not cut it. Keep the a/f ratio in the high 11's/low 12's and you'll be fine.

Yes. This is correct. Keep in mind that the likelyhood of running much over 20psi with +11:1 on pump fuel is risky business. There is no form of injection. You just can't get to 400whp on pumpgas with 650s. . . Well, if you run extreme fuel pressure, it MAY be possible. But an aggresive timing curve from an SAFC will bring that likelyhood to zero.

bardabe, your timing advance is TERRIBLE!!! If you want to know what your injectors are doing, you should log it. Is there a logging system that records %IDC that you can have access? Considering your terrible timing advance, I'll wager that your safc is not fooling the ecu into running the 650s at all. And you could be breaking up because of running quite rich. An SAFC should yield more timing than stock in the curve, not less.

I'm no expert but something is not right there... Less than 300hp with a clipped and ported 20g?

That's what I was thinking.

I'll post the new data log when the silicone couplers + t-bolt clamps come in so you can see. i know the logs earlier where / are horrible getting 6 - 4* timing advance at WOT is horrible. However back then I had pipes that would blow off under boost, boost leak coming from the TB gasket and the Idle control screw now i fixed the TB and Idle air screw leak. gapped my plus properly and got 17* advance by WOT so i think i can still get away with pulling more fuel since im only correcting 12-18% right now (stupid me went to dyno without fixing those boost leaks on shitty couplers) so im sure i still got shitty AFR's

Your boost leaks would account for all the lost hp on that dyno. It's a wonder you pulled as much hp as you did .
