My compound turbo set-up

[99gst_racer]

Here's a little 1st-3rd pull.
It's mostly untuned right now and only running 28 psi, but it pulls nicely.

I must say, it pulls nicely Can't wait till its running correctly

I wanna see from a roll at 2 grand or less, in like 3rd or 4th gear.

I don't think I'm ever below 2K while rolling.
It doesn't start to make power until 3K, so I've been doing most of my pulls/logs from 3-8K. I do have a third gear pull vid, but it's pretty boring, IMO.


On a side note; My fluidampnr came loose yesterday while on my way home. I limped it the last few hundred feet, but boy did it sound violent. I lucked out that nothing bad resulted from it. I must have forgot to torque it to spec a few months ago. It's good now though.

Nice that you have a private road to record 100mph speeds on

If it is possible to mount the camera on the outside of the car a roof or side panel shot of a drag pull would be sweet. Otherwise having a buddy on the side of the road shooting a drag launch from a hundred yards in front of you and filming you go by would give us some perspective of just how fast this beast is. Seeing your speedometer fly around was pretty impressive on it's own though.

Of course drag launches don't really show off all the benefits of your setup though. Getting some dyno charts will probably help convince any non-believers and get you nicely tuned at the same time

Great work and thanks for sharing.

3rd gear pulled like crazy, at what rpm do you reach the 28psi?

A log from last night shows 15 psi by 3500, 20 psi by 4000 and 28 psi by 4500.
I feel there's much room for improvement yet in the spool up time with a good tune, but the added torque from this set-up really gets the car moving quickly.

 

[andy4g63]

Good job, Paul... Car pulls really strong.

 

[TRSblader]

Looks really nice and sounds great man. I hope you can get it completely tuned soon and possibly get it on a dyno and make a few track runs with it.

 

[dsm-onster]

WOW. What a pull!! in the lower rpm range. I'd like to see a good tune on it not just a base tune!

We're working on it. The only tuning done in that vid was the removal of fuel in the backhalf of the RPM range. It would otherwise shudder a couple times above 6K.

 

[brian9397gsx]

very nice work. were are the doubters now? jk really looks good and its something different to cant waith to see a log for this beast.

 

[endeffect0]

I demand more videos! (as if you haven't made enough of a contribution to our little dsm world)


I would really love to get my hands on your logs... not like that.. in the totally strait nerd sorta way.


Idle hands do the devils work

Paul, are you using NLTS feauture ??? Cause it doesn't seem to drop a lot of RPM, even from 1 GEAR/where drops most/.

And BTW, you mentioned before, that Hallman would have to make you boost controller. I don't know why, but you can buy any Halllman MBC and the fittings are 1/8 STRAIGHT. The 1/8 NPT fits perfect in place and seals better. LMK, if a I misunderstood your intentions...

 

[Black_Bullet]

Looks good, those kelfords must be working out for you. Seemed they couldve pulled even harder and farther, especially once tuned!
Nice video of your speedo at your local 1/8th mile race track, you dont have to tell us what time it ran

Yeah, NLTS set at 6K.

Although, stupid me - I mounted the camera directly infront of the back half of the tach, and didn't realize until that recording. I had to try to listen to shift, and as a result I also was shifting much slower than usual. Naturally, I'm going to move the mount.

I spoke with Mark about doing it last year. I was going to send him the appropiate AN fittings, and he was going to drill the small hole, and put one in the lathe to machine a seat for the ball to sit. Aside from the price of the fittings (less than $3), it wouldn't cost any more money.

But, I'm broke right now, and I also need to set some money aside for the Shootout and a trip to the dyno.

Yeah, they seem to be awesome so far. Hopefully I can experiment with 9K shifts for test data sometime soon. Don't know if I have the balls yet though. Airflow climbs quickly and peaks with whatever RPM I take it to, so I'd like to see beyond 8100 RPMs.

 

[andy4g63]

Just get a ceramic ball and heavier spring. I happen to have an extra -4 to 1/8 NPT alum. fitting and also I have the old METAL ball. I just ran down and measured it for you. The ball/which is the same size, as the ceramic one/, fits PERFECT against the 1/8 NPT side of the fitting. I drilled a new smaller hole in the middle of fittind/ on the nut/ and it works perfect. It could be about 0.055-0.058... the hole doesn't really matter, it has to be there to bleed off boost, but as long as you run higher boost/at least 6-7 PSI, or more above the WG springs rating you should be fine. Smaller hole makes you turn the KNOB a few turns more. So if you cranked the MBC enough, WG should open rapidly, compared to little slower response, if have only 2-3-4 PSI over spring rate.

Until i turned up the volume it swept through the RPM range so easily i could have sworn you were in neutral. Looks to be a very broad and flat curve which IMO is the best way to have it.... especially for the street, after all what good is a 2000RPM wide power range on the street where you're using more of the lower end of the rev range 85% of the time...whatever i'm trying to say it equals ME LIKEY CAR!!!!!!!

Very nice work and i can't wait to see the progression becuase i know for a fact you're not just going to leave it alone

 

[blcknspo0ln]

Paul, I've got goosebumps listening to your car . It's gone a hell of a long way from back in the hay-day and I hope the younger members know that! Congrats on the new beast setup!

 

[hdoerr]

I may be Captain obvious here but as strong as the car is now (doubters) once its tuned it may be hard to control, it already makes a $hit ton of torque

 

[Bluefire16]

Damn, 0-60 looked to be about 4 or 5 seconds! And to 100 about 10 or 11...thats crazy. Please bring this car out to the Dawg Dog car meet in Grandville....the local gathering on Friday and Saturday nights....

I love that part

 

[joey17]

i think because of this new found turbo set up ( for dsm's) he should be on the web site home page insted of the one lap of america vr4.

 

[RipperXX]

Updates?

 

[99gst_racer]

Nothing much. The car is running strong. We're still doing some tuning here and there. I did just recently order a MBC from hallman, so I'll have the boost cranked up to 36-40 psi hopefully by next weekend.

I plan to drive the car to the Shootout in a few weeks. I also plan on dynoing it a few weeks after the Shootout, so I'll have video of that to share as well.
