The Making of "Evil Spirit"

[bansheenut420]

Did they say anything about a .70 dsm housing? My housing is the dsm style turbine outlet flange, so I hope they are making one. Otherwise, I am stuck with this housing till I go with a new mani becuase the dsm housing has a outlet for an internal gate, which is where we are putting my external. So, I am hoping they make one in the dsm style. 70ar

I doubt they will make one. If Jackson hasnt built anything yet, then you would want to modify a manifold to run an external if possible.

BTW I just laughed when I read this on the sale portion for that housing.
"New center section to turbine housing clamps included."

I know certain dodge vendors dont believe in doing that.

He said nothing about ever making a DSM outlet. He did say that if your running this .70 a/r housing then you should be running external anyway. I don't see them making a internal/dsm outlet at all as all the high power DSM's are running external WG's. He said they would have to do a whole new casting and is wasn't likely that the demand for them was there. We are out of luck with Holsets unless we get a new manifold with provisions for a external WG. I was also planning on running the dsm style outlet and using the internal hole for the external WG like Wallace. Oh well................

Thats what I am doing is the setup like wallaces. Well, I guess its time to start saving for one of wallaces equal length mani's. I would like to talk to the bullseye people though.

But, Brent, you are still porting the hell out of mine right?

[Ondonti]

maybe if you have something to bolt it to

Funny story..................

Spirit R/T vs BMW M3 + 350Z

Finally made it to the Dyno to get some starting(kind-of)numbers for my car. I had been data logging KR and the Dyno proves its really there, between 3-4K rpms. I have another crank sensor that should be here Friday/Monday. I am also going to change my knock sensor, right now I am using a knock sensor from "the parts store" since I broke my original when putting the head on. Overall, i'm impressed with what my car did on 10lbs! The first run was with my cut-out closed - second was with it opened. I picked up 27.5whp and 13.3 torque just from the cut-out! 242whp peak HP. I wanted to turn the boost up but I won't until I get the KR figured out. I should be in the 3's with just a upgraded turbo and same boost. As you can see, these runs are on a DYNOPACK chassis dynamometer..............the ration was blacked out because I didn't want to confuse anyone, it's not the gear ratio. Also, A/F ratio started around 10.1 and got up to 11.8 by redline so there is still some more power to be had - egt's top out at 1390 i believe it was. Though it says "Flywheel HP" it is NOT! It is WHP.

I talked to David, the owner of Bulls Eyes Perfomance, and he said there wasn't a demand for the .55 housing anymore. The DSM guys, who dominate the Holset market(other than Diesel), wanted a larger housing so they made the .70 for them. Most of those guys are running aftermarket equal length manifolds with external WG anyway, so their golden. Precision to the rescue!!!!!(digging in pockets)

Here's a thought, have you try to buy a .55 housing from the DSM board?

Yeah I tried but, not hard core. Went to DSMtuner and a few others and looked/asked but no luck. I had asked Wallace if he could still get them and he was going to check and get back with me and never did(I never did either,just assumed he couldn't). I see he just posted in another thread that he could still get them so we might still be good! I will most likely be going another route though. You still got that oil pan?

Who would do somthing silly like put a .55a/r dsm housing on there hoslet.

[bansheenut420]

Great numbers for the amount of mods you have! nice.

[rx2mazda]

I thought so too, thanks!

Yeah, way to small. But seriously, TIII's seem to be all about RPM's/Flow up top and a .55 a/r will begin to choke at the top of the power band. I'm sure you can make a lot of HP with one(.55), as it has been done. I was looking forward to doing it myself, especially for the price, but I will go another route now.

You are still running stock injectors correct?

If so, although different dynos were used, your power numbers are very close to what mine were when my car was in a similar state. With an A/F of around 12.2-12.3:1, power was 246 whp. When I uncorked the exhaust and ran through the bypass, the A/F went to 13:1 and power jumped to 258 whp.

So, your values are making sense as all cars in respectable shape should be making around the same numbers.

[rx2mazda]

Yes stock injectors. Actually, they are injectors from a 92 iroc r/t. Rick D told me that they flow a tad bit more than stock 91 injectors. No one else says this but, he said trust him, they flow more! My fuel pressure is lowered to 52 base and still running a bit rich so it makes sense.
