319 / 360 @ 9.5psi

[_J_]

Well I went to MM today ...

I think I have some type of issue with the new toy .. the numbers
are a ton lower than expected ..:(

319whp / 360tq @ 9.5-10psi the new boost controller I am use does not
jump all over the place as the old one .. but even so what the F* is going on
with my power .. I'll post the dyno sheet later ..

at 10psi with the 4-speed Auto and 19" wheels on the same DynoJet I made 360whp / 404rwtq @ 10psi

now with close to the same psi level with a 03 motor, stock tires and a 5-speed 319whp / 360rwtq :banghead:

the only other difference is the Roush comes with Aluminum drive shaft, and the
stock v6 does not, also I could not find a 70mm BBK so I was force to get the
65mm BBK, and the lower intake on this thing had the F*ing IMRC in the lower ...

also the tune is 100% MM's and not from Andy or Justin .. but who knows ..

Matt, Gary ... anyone thats knows .. WTF!!! is going on.. no matter how
much $$$$ I spend I just can't seem to get what I wont!! %$YT$%Y^ :banghead:

Hmm I don't know , was the clutch slipping maybe ?

[OrangeV6F150]

You would think the IMRC's would help with torque.Maybe your clutch is also slipping some:derek:

Edit:I posted this at almost the same time Gary did..lol

[062stang]

clutch slipping?

whats the miles on the 5-speeds motor? maybe its loosing compression

-umesh

yah me too hahaha

great minds thing alike

-umesh

[OrangeV6F150]

Also looks like 40hp and about 40trq from the 10psi to the 9psi.I could also be the tune.Do you know how much timing each tune had?

[GT-EATER]

OK J its unanimous the clutch was slipping :laugh2:

[_J_]

Well the clutch was burning you could smell it .. but still
that’s a major diff in power for the setup.. going to put on
my old stock 2000 lower (none-IMRC) and see how much
that helps..

but for now.. going to work on my #1 stang again this is getting crazy..:cry:

only got 19k miles on it .. very clean and well service car.. I also did a
CP test .. did not do a LD test .. but the CP test every cylinder was in the 190psi range

[062stang]

you have awesome problems :)

post some data. someone here should be able to figure it out or point you at least in the right direction.

Thats a lot of torque on the stock clutch J turning that heavy ass 32 lb stock flywheel :banghead:

IMRC can only help with TQ on a N/A car ... on a FI car you need all the
air in the cylinder, the N/A car pulls air in so having less open running
gets more air in.. F/I car it will only cause you to hit higher boost quickly..
(well pre-set boost setting that is)

lmao... :D :laugh2: .. thanks I needed that.. :)

my old setup had 12* timing, and this new one has 13* timing

there is also one more thing .. I forgot but still don't know if its a factor
my exhaust pipes muff pipes are 2" and my old setup I had 2.5" full Mac's

ok so .. put in a better clutch .. was planning to do that anyways,
and I'm going to swap out the lower intake to my 2000 one..
back to the dyno :banghead:


Thanks guys.. feeling a bit better now :)

Put in a Spec aluminium flywheel , then you can mount up a 10.5" clutch :chrisb:

cool .. Gary can you link me to a place to buy both?

Thanks ..

the smaller exhaust[pipes could cause mroe backpressure thus the 10psi, which with the larger exhaust pipes might only be more ike 8 psi or something. SO the boost numbers may be a reflection of that. I know on the Supercoupes they getmore boost then on the Mustang with a SC setup cause the mustang has a better exhaust system. We make about the same power but different boost, if I were to up my boost to match the SC's I would make mroe HP boost for boost. Just a thought.

[TuxMask-Andy]

The numbers seem just about right.

I remember at 10.3 psi i made 334 rwhp 389 rwtq at 10.3 psi on 15" rims on a 5 speed with aggressive timing.

Also all my customers at 9-10 psi are making around the same numbers you've posted about 320rwhp and 360rwtq. Gash05 just made same hp likes yours as same boost level. 320rwhp 360rwtq

For some reason your numbers always been high on your twin kit. I've always wondered if the mustand dyno calberation was off or if its just an auto thing. Since it was done on the same dyno i really don't know. I've always wondered if the twins were just that much better then the single.

Just throwing out a few possiblities but mostly all my customer are making that 320rwhp and 360 rwtq levels at 9-10 psi for the single turbo setups.

I wouldn't be 2 dissapointed numbers looks good to me.

[_J_]

Andy if it was a single kit I know the numbers would be normal,
But even Justin old kit makes 340+whp @ 10psi

Also including the fact that I made 360/404 @ 10psi on a DynoJet
with this kit before with the Auto .. 5-speed should show more
power and better curve and that’s not the case here ..

Something is very wrong and I'll find out what it is .. this car
has a 2" exhaust instead of the 2.5" the pipes where meant for,
a 65mm TB instead of the 70mm on the other one, and a steel
drive shaft, instead of an aluminum that comes stock with the Roush,
plus it has IMRC in the lower ..

going to upgrade each things to equal my old stock setup and
see what the numbers look like then...

but I know issues are with the car not the kit as it is proven already
it takes real power to push a 3800lb car to 12.1 @ 110+mph
so with I'll find out whats wrong with this car .. unless Auto makes
more power that 5-speed lmao..

[matthewneuharth]

the clucth does not spin the flywheel gary. ;)

also your 2'' exhaust will hurt you with out a doubt. 10,20? not sure but on a turbo car. you want as little back pressure as you can get. soo there is hp to be had for sure.

also you take weather into account? cause a boosted car will be effected by the weather alot.

[Stangcharger]

What was the wheather like up there? ive lost as much as 30hp on the same dyno just one was a ton less humid than the other day.

also it could be the exhaust as well. those are my thoughts.

sorry matt read yours after posted mine and realized i said the exact same thing. :uhh:

[TuxMask-Andy]

ya i missed the part about the 2" exhaust. jeez thats small. Thats what stock is. Probably comparable to a single 2.5" in terms of volume friction flow.

That will definetly hog some hp.

Sometimes on dynos with autos they get torque flash which creates huge torque spikes if the dyno operator doesn't lock it into 4th gear. Does happen sometiems if the dyno operators are lazy. I also noticed i lost about 15 hp on the 2nd run from heat soak if you don't let the car cool down for at least like 10 minutes before each run

haha thats been happening a lot in this thread.

i was gunna add that my singe setup made 342rwhp and about the same torque. and that was rush job too and on a stock drivetrain.

i wonder if the Al drive shaft will make up the difference? and i think the magazines say that mathematically they don't, but the upgrade will show it self on the 1/4mile.

are you going to do the upgrades one by one with a dyno pull each time?

-umesh

[MSP]

Hang in there J-Dizzle! You'll get it figured out.. Ballers never quit, they just get more determined..

I think that 2in exhaust is a problem in terms of HP.. I would swap that out ASAP! I wouldn't go any smaller than 2.25in per turbo, and dump it into a dual 2.5in..

Also take care of that clutch.. I'm sure it was slipping cause with the 2in exhaust, it created lots of back pressure @ 9.5psi..

J-Dizzle for the Win!! :chrisb:

Auto's done properly are locked in 3rd gear for the pull.

Thanks for the great feedback guys, sorry been crazy busy with work
and all .. got a race lined up for Auto on the 13th ..

anyways I also found out that my temps was crazy high with the
air filter in the motor bay, IAT temps was 138* .. at 12psi with the
other car and stock motor dyno temps was in the 80-85* at the
end of the pull .. so with so many things not the same .. I think
she got a lot left in her.. but yeah I truly need to get my #1 car back
up and running going to spend some time on her this weekend..

Thanks all... I'll post pics / vidz and stuff soon..
