Stillen SC Build 500 WHP?
 

Ok so thought I would start a new thread, Because not broke down any more but turned into a bulid thread, So here goes, I am trying to see if I can see close to 500WHP with the Stillen SC . Mod list is below. Thanx for all the help in the broke down thread, :)

Super Charger Upgrade SCI to SI

34 Tooth Count Jackshaft Pulley

30 Tooth/35mm Supercharger Pulley

Gates belt Part numbe 560 8M GT20 for the cog pulleys

idler assembly from a 03-05 350z bracket

Bosh EV14 Injectors 850CC

UPREV MAF's

NGK plugs DILKAR8A8

WAT001026 Frozen boost.com Heat exchanger

Upgraded Intel pipe 2.75 made by ???

Turbosmart TS-0203-1022 Kompact 25 mm Dual Port Universal Fit Blow Off Valve

If you can manage to make close to 500, let alone on an all wheel drive X... I'll be extremely impressed.

Good luck OP! :tiphat:

Hey Staples , Remember tho the X is RWD , Till they slip, The 412 I made on the stock kit was in line with the RWD guys. If GTM can do it why can't I with Stillen LOL..

So are you going to try to go to blow-through with the new piping?

Godd luck with the build! Will be watching for updates:driving:

No was thinking about it but would have to put the stock manufold back on, I think or some of us think with the air intake made larger and upgraded MAF's should be enough. We'll see tho, Beening blow through or not , May not matter.

Good luck with your build. :tup: I'll be watching this with interest. :D

Great news - we'll all be watching!
What's the new idler assembler for?

If you decide to go back to the stock manifold and need the upper pipes that attach to the TB's, let me know. I have an extra set from my GTM TT install with brand new sychronic BOV's and the MAF housings. Good luck - hope your new set-up works well...

you know im in for updates anmvq

Sub'd...so been dreaming about purchasing an SC next summer...

Hey man where you been hidding, LOL The idle pulley is for the cog pulley set up because I need to used a different belt. Should be done in 2 weeks

ZKraken22 OH I know you ARE !!:tiphat:

Thanx man we'll see

Epic........

Subscribed. Wanna see what you get from this setup! :driving:

They have a rear differential with a transfer case to the front wheels, true.

There would still be more drive-train loss due to the transfer case being connected to the drive-shaft compared to a full rear wheel drive G.

When you get the cogs on start with the stock pulley that comes with the kit. You will see more boost with that pulley than the 9 pound Stillen pulley I think around 10-11 PSI

Here is my old graph with the Maf's maxed out @6600 Rpm's with the small intake Stock Stillen pulley. You should be able to leave where I left off at.

Yea thanx man, I will not be getting the 9LB pulley from stillen, I see 9 now(Stock pulley), if I'm going to see 2-3 more PSI with the cogs like you I'm going to see 11-12, with the SC upgrade should add another PSI maybe 13? If I went 9PSI pull I would 14!TOO much I would thing on Stock block.

Good you should be able to match my number's at a minimum without the dip's I have.

I am looking foward to seeing your results.

hope too, And take off after it LOL



We'll SC should be on it way back to me today, Just waiting to talk to Stillen today. Will be calling them in about 30 mins.

ok i am interested in doing the cog pullies also but i do have the 9lb pulley
do you have any pictures of that set-up

Same^^^ would like to see detailed pics please.

Will have full pics when I get the car back, I just spoke to Stillen and Vortech sent my SC back to them yesterday, So they should see it today and be able to send it back to me. I also asked them about a one off intake for my set up. 2.75", Still have yet to find someone to build it.

What did you make with the 9PSI pully 425ish?

With that pulley I was seeing 11psi at redline

WOW!! 11PSI with only the 9lb stillen pulley???

what WHP and TQ numbers would you see with a 9lb (11psi) pulley???

im guessing very close to 500whp...

No? Around 450-460.

Really?!? 460whp seems very low for 11psi of boost. Lol. I would never want to go past 8-10psi on a stock block

??? There are guys over 500WHP on stock blocks? Remember the SC builds boost all the way to redline, Unlike a turbo where you see ALL the boost at once, 460WHP @11 psi is really good. I'm shooting for 14 and 500, Proably not goin to get there but want to be close,

Thanks for clearing that up for me.
Is a SC safer then turbo on a stock block then ???

SC IMHO is safer because of it building to redline vs all at once.

On a side note I am making 432hp at only 6psi and that is on a mustang dyno and after taking some timing out reducing the hp. on a dynojet it should read higher so I do not know why you have to make so much PSI to get the same as I am. I know dynos are subjective and are only there for tuning purposes but it would be nice to be able to compare numbers from each of our cars based on the mods we have.

Hey Kelly, Yea man on 9 PSI I'm making 412WHP( Mustang dyno) low dyno in my area, Not really sure how you are making more or WHP and 3 less PSI, That those are turbo numbers, Plus I have a AWD 7 SPD auto,, But the 412 is pretty much in line with everyone else @8-9 PSI,

Yea plus for what Kelly said, Becasue it builds it as the RPMS rise and just doesnt slam it all at once, TQ numbers are lower but us with the autos dont mind that really, Would rather have my tranny work then make 380WTRQ :tiphat:

I am not sure either i know that WOW370 dynoed on the same dyno as me and he did 464hp and he has a GTM TT setup. I am also a Manual as well but do not think that would make this much difference. I know my tuner knows what he is doing. jsut to give you an example initially it was tuned down in WPB and I new I had problems like WOW370 so we got a new tune at Z Fever here in Tampa. the tuner did a initial pull with their tune at got 397hp vs the 405hp WPB said I had from their mustang dyno then we did about 20 pulls to get things right then pulled timing to ensure safety then let the car cool and pulled the final numbers of 432hp. I am not sure how I only made 30 less hp that a TT setup but I am not going to complain about it. :tup:

I was doing some research and thought of an explanation why reducing timing would gain more horsepower .

Naturally aspirated versus force induction

A normally aspirated engine doesn't use a compressor or nitrous oxide to enhance combustion. Since the fuel-air mixture in its combustion chamber is less dense, it takes longer to ignite. Vehicle manufacturers typically set the timing at a default that will lower engine temperatures and reduce emissions. Advancing this setting increases the engine's horsepower by firing the plugs earlier in the compression cycle. If your plugs fire too early in this cycle, you get so much pressure and heat in the cylinder that the fuel-air mixture can auto-ignite and damage your engine. Turbocharged, supercharged and nitrous-injected engines are already running higher pressures and temperatures than normally aspirated engines, so the consequences of advancing your timing can be more severe. Retarding the timing on these engines compensates for the denser fuel-air mixtures by firing the plugs later in the compression cycle. This prevents premature combustion and allows the engine to run at peak performance without destroying itself in the process.

Count down begins, The SC is on a UPS truck on its way back to me, Just made my APT for my return for the 25th, Hope 11 days is long enough to get everything together, So excited, :)

How much are the cog pulleys and how hard are they to install?? will stillen ever know you have had them installed if you send back the blower for warranty repair??

Are there links the the exact pulleys I would need to order??

Sorry for 21 questions. Just trying to educate myself.

Thanks in advance.

The pulleys are not hard to install, But you will need a tune or retune.. I got all my parts from Auto Anything- Which came strait from Vortech, An my Stillen Warrenty is up in DEC but now is VOID, Becasue I upgraded the SC, But Vortech warrties it for 1 year from now. I Blew Stillens warrenty with custom tune anyway.. But really I only pick up 40 WHP on Stillens tune and pick up 72 more with the custom tune, Total was 114 WHP total is what I picked up from my NA bolt on # of 298 WHP ! :)

Yes Stillen know that you switched to the cog pulleys and void your warranty.

ANMVQ can pass on the cog part numbers and information I gave him .

You can also read this for more information

Keep in mind if your a person that is real worried about warranty then doing the cog set up is not for you . It is something that is complicated.

I'm not worried about warranty sense I'm supercharging my car. Just like to know my options when **** happens. Lol
Please Pm the info. Thanks. Well appreciate.
