Hi,

Is there a Vishnu Stage 1 Dyno I can see? I already purchased it from Shiv (Vishnu) and will have it installed this weekend.. just wanting to see a before/after.. I found a stock 335i dyno, but haven't seen a Stage 1 dyno yet..

Thanks

Hope you did your research on Vishnu exhaust...It drones like a bitch!

[michsu]

really? is it that bad? aww... I already paid for it and it's coming this Saturday... do you have a link I can take a look at? All I hear are pretty good stuff about it...

[down4it]

I heard the exhaust on Dan Harmans car and it sounded really good... On a stage 1 PROcede i dynoed at 339WHP and 380WTQ with exhaust on a dynojet at correction:STD smoothing:5.

[michsu]

ok, thanks down4it.. 339/380.. and I found a stock 335i dyno that is 276.40/288.31... so an increase of about 63 hp / 92 torque for me regarding the stage 1 installation? I was hoping for 100 / 100 at least.. like what the Vishnu site claims..

Direct quote:
"Today's runs were on 98 octane, not 91oct pump gas. These results are with stock downpipes/stock primary cats. We will be installing catless downpipes as soon as we get them from Riss Racing. That means that the only exhaust mod is our cat-back which replaces the secondary cats. We are still running the stock intercooler and diverter valves as well."

why does it show that Shiv got 407 / 427 (difference of 129/139 from above stock numbers, even with a loss of 10%, BOTH numbers should be above 100) on just stage 1? Although it is 98 octane, does that make a big difference over 91?? I would think probably at most 10hp, so not that much difference...

[Mr. 5]

Here you go.

Don't be afraid to search.

[michsu]

thanks Mr. 5.. but I already found a stock dyno.. I'm just wondering why the Procede claim is so high.. just because he used octane 98?? Vishnu's claim is that with Stage 1, you should be able to get 400-410... I'm assuming that is not including the 15-20% drivetrain loss?...

405 (average) x 0.80 ==> 324, so 324 hp / 324 torque??

maybe my calculations aren't correct..

according to your page, The Procede had a gain of 53 whp and 77 wheel torque.

Add in their Stage 1 Exhaust, it should be able +10-15 increase for each?? That would come back to my numbers of "so an increase of about 63 hp / 92 torque for me regarding the stage 1 installation?" above... hmmm.. I was just expecting better.. that is all...

[jcarlucci1]

405 X .85 = 344 at the wheels..thats about right for procede v2 and exhaust.. what made you think you were going to gain 100 horsepower at the wheels?

[michsu]

still learning here... sorry about that.. I just figured the website said 400-410...

so just on the Procede V2, I am supposed to get 344... so a increase of 276 to 344 about 70 hp... that's pretty good I suppose..

[dwykstra]

it's not really accurate to use someone else's baseline dyno as your own. your gains could be more or less than expected depending on what your own baseline is. i'm still new to this, but from what I learned, every dyno is different, and every car is different.

[Supramano]

when vishnu clamis 400-410 hp they mean at the crank. Hp at the wheels and at the crank are completely different. Having 400-410 hp take 15% off for manual and 18% off for autos...that leaves you with a loss of 60 hp for manual or 70-75 hp for autos. Brings you to about 330-350 range which most people are getting with v2.

On another note some people, not all, make the simple mistake of calculating their real hp according to the hp at the wheels. The drivetrain causes a loss of power from engine to wheels. So it makes sense when a 400 hp engine car puts down 340 at the wheels due to a 15% drivetrain loss, since 15% of 400 is 60 hence 400-60=340. But some people get their car dynoed and see a 340 hp result and then add 15% for drivetrain loss. 15% of 340 is 51. Which then comes out to 391 hp. Just wanted to clear that up in case people were confused. bye bye

[michsu]

thanks a lot guys!! that's very helpful!! like you said, every dyno is different.. but just want a nearby figure that I can use everyone is so helpful!! thanks again!!

this is like 450-460 at the crank, stage 1 ~

[e90AW335i]

From Vishnu's Site:

Stage 0 : PROcede V2
Stage 1: V2, and exhaust
Stage 2: V2, DPs, exhaust (which is the graph above)

[Driver72]

Stage 1

355-360 rwhp
370-375 rwtq

on a DynoJet STD depending on 91 or 93 Octane

That's pretty much what you can expect.

That's equivalent to having
410-412 crank HP
445-448 crank TQ

Stock 335i's on same said DynoJet make
265-275 rwhp
275-285 rwtq

So Stage 1 Vishnu tune will give you an increase of:
~85 rwhp
~92 rwtq

That's a gain of:
100 crank HP
108 crank TQ


You will be happy with the power gains.

That dyno includes catless downpipes and vishnu's prototype intake..definitely not stage one package.

+1

catless downpipes and intake are a big power adder it seems, especially w a tune designed to maximize the benefits of the new air flow properties of the engine.

Me want.

[michsu]

so it is almost 100/100 then?? guess I have to get an intercooler (SPEARCO?) or air intake (MSDS Stage 2?) to get it to about 100 / 100? well, one thing at a time.. haha.. I live in Los Angeles..where can you find higher than 91 octane? Is Chevron any good? I hear that people only recommend Shell or 76 here..

Stage 1 vs Stage 2 has that much of a difference?

Stage 1
355-360 rwhp
370-375 rwtq

Stage 2

390 / 390

so an increase of 20-30 for hp and torque just for the downpipes and intake? What would you guys recommend for the next upgrade? Seems like the Air Intake Stage 2 is cheaper to go with.. haha.. I hear that the intercooler from Spearco can also do about 15-20 for both hp and torque?

I have these to look at :
http://www.namotorsports.net/detail.cfm/part_cd/MSAC335
$374.99 -- Air Intake Stage 1
$224.99 -- Air Intake Stage 2

http://www.turboneticsinc.com/produc...category_id=83
$1500 -- Intercooler Upgrade

http://www.ultimate-racing.com/Produ...P-Coated.shtml
$1135 -- Catted Downpipes

Thats graph is not SEA corrected... it doesn't count!

[Driver72]

So far catless DP's have shown to be worth about 15-20 hp and tq
High Flow Catted DP's are probably only worth 6-8 hp and tq
A good CAI seems to be worth about 8-10 hp and torque.

So yes, catless DP's and good CAI would give you 25-30 rwhp/rwtq
