D-1SC installed!

[Tripoli]

It was a bumpy ride, but my D-1SC is finally installed, and she got tuned by Manny at HPP this afternoon. She put down 473 RWHP and 422 RWTQ. That's a little more than I was trying to get, and considering that my shortblock is stock I'm going to have to be a little gentle.

Here's my dyno sheet:

That's awesome!

 

[mazen189]

thats a lot of power going on under that hood. It must be really exciting for all this. I wish those stock internals a safe haven.

 

[hotstang_46]

I have about the same as you with the stock block. I added meth to make it live. I hope you did the same????, or intercooler. If you didn't BOOM...soon

 

[Tripoli]

Got the good 3-core intercooler. The tune is pretty safe. I'm just trying to keep it under 6,000.

 

[spederman]

Damn dude, nice numbers for stock short block. How many PSI are you running?

 

[Tripoli]

About 8 1/2 PSI. It's a 3.85" pulley.

 

[navarro98gt]

Nice numbers!!

So I’m assuming from your sig that you’re running VT stage 2 N/A cams. With those same cams and stock heads my buddy made 443rwhp and 400ftlbs at 9lbs of boost. This was with an intercooled Vortech V1. I guess those N/A cams respond well to boost.

 

[Tripoli]

Yeah, they're a 3-year-old VT grind. 108.5 LSA with .562/.576 lift and 225/235 duration. I see no reason to get blower cams.

So you are running a blower with stage II N/A cams!That is some sweet numbers .Maybe i don't have to swap out my VT/Cushman stage II N/A cams after all do get blown LOL!

Congrats!!

I've never bought into the whole blower cams thing. My understanding is that a car that makes more power N/A will make more power with forced induction. My friend has a D-1SC on his TransAm, and he had the same experience. Everyone said he got unusually good numbers for the amount of boost he's getting, and we think it's because of his N/A cam.

Looks like you have a bit of a lean tip-in. You might have your tuner adjust your intake manifold volume in the tune or another transient modifier value. A smaller value for the intake manifold volume should help. Result should be better throttle responce.

Nice numbers, though!

Yeah, when I shift the fuel pressure drops while I'm off the throttle, then it doesn't quite get back high enough before I'm on the gas again. I sometimes get a little hiccup before the pressure returns. It's very brief, but it's annoying.

I'm heading back up to see the tuner tomorrow. I'll see what he says about it. I think the real solution is to go to a return-style fuel system.

About 8 1/2 PSI. It's a 3.85" pulley.

Really I installed my D1sc on my 98 gt last summer but I'm getting it dyno tuned this summer coming up (never got into boost). I have the 12 psi pulley with the stockblock, maybe I should consider the 8 psi pulley.

 

[ADRENLN]

yes, that is very high for that amount of boost. i run 15 psi and only make a 30 more hp and 20 more tq. i have stage 1 miled blower cams. however, im not tuned quite right yet either. i am going stage 2 mph blower cam this summer....we will see how that effects things.

 

[Gauger]

Don't worry, guys. He's still slow.

 

[westgastang5.0Coyote]

Very nice numbers! And I wish your stock block all the luck in the world.

 

[Tripoli]

We took 2 degrees of timing out above 4,000 RPM and lowered the rev limiter to 6,050. She should be pretty safe now.

 

[oxfordgt]

I would jack that rev limiter up. You don't want to hit that while in boost.

The reason they make blower cams is because NA cams have a very big overlap and you lose alot of boost/a/f mixture. If you put Blower cams in there You would make alot more power.

My buddys car had a built block (same CR as stock) hand ported heads, CMS stage 2.5 blower cams with a D1-sc on 10 lbs made 535rwhp. Would have made over 550 on 10lbs but his litte gt40 pump and KB boost a pump werent up to the task. Had to shut down at 5600rpms.

 

[mustanggt04fast]

very nice numbers hoping to pull that out of my stock block with a turbo
