I have put this car on a chassis dyno....ill tell everyone what it made after i get a few replies.

350 (.030 over)
9.5 to 1
SuperRam upper & lower intake
Ported runners
36# injectors
1000 cfm throttle boddy
AFR 190 heads
Port matched with minimal work
DFI
1.5 roller rockers
224/236 @ .050 - .525/.525 roller cam
edelbrock T.E.S. headers
3" slp cat back system
700R4 10" 2700 - 3000
aluminum driveshaft
9" w/ 3.70

 

your probably in the 315-320 range.

 

I would say it should make about that also.

Im gonna say that is about a 450HP motor. At the wheels.......Probably around 370HP.

I think you'll do somewhere in the same ballpark as this one.

I'll say right around 300hp

Just curious, why are you running 36# injectors?

 

I bought the car setup basically this way.
Only I asked the same question about the 36# injectors.....only thing i can figure is because of the 3 stage dry kit that is run with the dfi, however it is only set for 85hp with all 3 stages on.

The car made
298 hp at 5600
and
409 ft.lbs at 2600 on motor at the rear wheels

I cant figure out why this motor only makes 300 at the rear wheels....exhaust would be my guess.
I makes an *** load of torque, just if i could get the hp near it.

Anyone have any suggestions why the numbers arent there and maybe how to get them up?

Im doing a 406 for this car and am going to use the same intake setup, with more porting i think.....probably afr 220`s ported.....not sure of the cam untill i get the flow #`s for the heads.

 

first check fuel pressure. Since the motor is making torque, I would assume that the torque is falling off before it should. FP could do that. Isnt' there some type of Wide band thingey that FI motors can use on a dynojet to tell the fuel curve?

Check cylinder leakdown. The rings could be not sealing at hi rpm also. Would still allow low rpm torque.

 

I think those are good numbers. 300 RWHP is a lot of power... Enough to smoke your average street cruiser.

I think it should be making at least 20 more horses though. Just by looking at your setup. You might need a reprogram.

 

fuel pressure stays at 43 the whole time
shows great on a leakdown too
we had a wideband on it when it was on the dyno.....it was like 12 something or 13 throughout the run
i took it to white racing and we tried a little change in the dfi, but lost power so we basically left it as is......maybe its doing all it can, i dont know

 

well ur running a 1000cfm throttle bodie on a 355, with superram intake. The guy who followed that route made the same mistake as GM high tech. Those intakes and 1000 throttle bodie are made for 350's w/ blowers or larger cubic inches. Im sure if u convert 52 or 58mm throttle bodie or get a blower ur hp should increase incredibly. Again the throttle bodie and ram is way too big for a 355.

:Yeah its not a chevy but damn how many 71' dusters have u seen in the streets.

 

Well, you got kinda a mismatch of parts there, that's why I guessed it at 300hp. Your intake side is a little big and your exhaust side is a little small. I would be most concerned with those big injectors and how the fuel map is compromised in calmap to make them work.

Vortech....58mm TB is 1000cfm While a 58mm MIGHT be overkill for a 350, the superam is definately not.

 

if i had to guess i'd say about 355 to 360 at the wheels for hp at about 6k. i'd say about 385ftlbs of torque at 4400 at the wheels.

 

That's BS!! 20 more?? With those heads and that cam he should be making close to 400 RWHP easy with more like 450 Ft. lbs of torque!!

My guess is the injectors and throttle body are too big for that 355....basically what everyone else has said!

With the super ram, those AFR heads, and that cam you SHOULD be able to pull 11's easy! Something is definitely wrong!

 

yeah, i cant figure out why there are such huge injectors in there.
ive thought about changing them, but with the dry kit adding more pulse width, i dont know what to do.
maybe 30`s would do it
but all the **** id have to go through with retuning the car would suck big time.

I personally think that the exhaust is the biggest power restrictor on the motor.
I just odnt know what to do about it.
Id like to have equal length long tubes under the car, but 3rd gens sit so low.
And its hard to find 1 3/4 or 2" headers for a 3rd gen.

 

Alpine...you could go with some hooker super comps long tube headers. They are 1 3/4 with a 28 inch long primary. They hang about 1 inch lower than my moroso 6qt pan. While that is low, it's still definately do-able.

You said that the fuel pressure stays at 43psi "the whole time"...do you mean it doesn't increase when the manifold vacuum is removed?

BTW, anybody that says that motor should be in the 11's easy is a little ambitious. 11's don't come easy period

 

i thought the 58mm was a 1000cfm throttle bodie. Anyway lingenfelter said it himself to get the best advantages of his ram intake, u must get the cam, heads and other of his parts for an increase in power. I could be wrong but thats what it says in his add.

 

Alpine, join the 'not happy with rwhp club'. It happens to all of us. I have a 383 with smaller injectors, a smaller cam, and basically the same setup as you, and get the same hp.

I am pulling my heads and intake to have them ported soon, and the compression raised. In looking and comparing my combo with others, particularly LPE superram motors, it seems that 9.5:1 compression with aluminum heads is worth about 20 horse when upping the compression to 11:1 and higher. I am going to have my heads hogged out, and the intake ported and extrude-honed. Hopefully that's where the power will be found. I think there is also some power to be found in the tuning.

 

Well, im happy with the torque numbers....just cant figure out how to the the hp up there too.
My fuel pressure stays at like 43 through a dyno pull.....at idle its at 36.
Id like to get my intake extrude honed, but i dont know who does that process.
The car goes 12.70`s on motor, but i think it will go faster when i put the trans in it and play around a bit.

 

My opinion (and worth every penny you just paid for it) is that your headers are too small. Get some 1-3/4 headers from SLP or someone else. Also, the compression ratio is MUCH too low for a cam with the duration numbers you are showing, ESPECIALLY with aluminum heads! Lastly, the injectors are too big, which causes you to lower the fuel pressure pretty low just to keep it from going too rich.

Any idea what your injector duty cycle is?

next time i put my laptop in the car ill look.....im pretty sure the dfi tells me the duty cycle of the injectors.

 

He's running 12.7's with only just over 300 RWHP!! 11's is EASY for a setup like his....if running properly!! TYVM
