Steg V+

[PKFIRE]

Thanks to 2kSVT purchasing my MAF sensor on my 03 Cobra over the weekend I decided to go ahead and remove the stock blower and install my Steg V+ blower that I have been putting off for awhile. So first off thanks 2kSVT to get me motivated to do this and if you read this good luck on your blower install.

This weekend I removed out the 39lb injectors, blower, and MAF sensor to get it ready for the new parts going in. I bought the 63lb EV6 injectors which is a direct connect for the 03/04 Cobra's. I headed over to Cincy Speed Saturday and ordered a BA3000 SCT MAF for the added flow that this new Supercharger will hopefully add. I've been quite content with the just the 2.8 pulley setup for awhile. I guess it was just time for a little bit more power. I'm going to reuse most my gaskets and just replace the supercharger gasket since it got a little bent during the removal of the supercharger. I didn't realize how easy it was to remove hopefully the install will go as smoothly. After that a trip to Cincy Speed and then I'll let Adam work his tuning magic. I'll just need a base tune before I can drive the car to the rollers.

Hoping for 500whp or more
2.8 pulley, FIPK, Magnaflow Catback, Steg V+, Dragon TB, 63lb, SCT BA-3000

Currently
459.97whp, 462 ft-lbs of torque
2.8 pulley, FIPK, Magnaflow Catback, Dragon TB,39lb stock MAF

I'll post pictures later.

Waiting for pics and numbers.

[PKFIRE]

I purchased a new Supercharger Gasket from Kerry Ford today and I still need to get some coolant for the supercharger. Hopefully tomorrow my BA-3000 comes in and Adam will place a base tune in my Hand Held so I can drive it to them when it's time for the Dyno tune.

[plated]

hell yea about damn time..500 rwhp should make for a fun ride:popcorn:

[cobraman302]

Hell yeah! mine put down 510rwhp with just a stage 4 Steg port stock injectors, MAF, and throttle body.....you shouldn't have a problem obtaining 500rwhp.

[PKFIRE]

Well hopefully mine puts down those numbers, I will be adding a X-pipe into the mix also. I have the 2.8 pulley mounted onto the Steg now and picked up my BA-3000 at Cincy Speed today.

BTW does anyone have a lower intake bolt, I broke one of mine today.

[PKFIRE]

Also I want to make sure what the exact lower intake torque specs are.

I took this off of svtperformance

"(now its time to bolt the lower intake to the cylinder heads. refer to the last picture for the torque sequence.

i didn't see specific #'s for this step, to i just went with the following:
1st tighten them to 50 inch/lbs
2nd tighten them to 10 ft/lbs
lastly tighten them to 15 ft/lbs (i always go through one last time to make sure all bolts are at the final torque spec))"

this is what I used I'm just checking if it's right or not.

[PKFIRE]

I looked up torque on a M6x1.0 8.8 bolt and it is 7.8ft-lbs. I guess I can't trust the internet because I use wrong torque on the intake fasteners.

[cobraman302]

Wish I could have gotten to this thread sooner man, these bolts will snap with too much torque. To my knowledge **disclaimer here** lol, they should be at 89 inch pounds (equivalent to about 7-7.5 ft. lbs) then turned another 90*

[PKFIRE]

You're good, I just wished that I didn't use the torque in the write up. Other people than I did the same thing and I hope that the write up is changed. Luckily the bolt did not break flush and it was easy to get out. I have the blower in place again and as soon as I have a new bolt I'll finish the install.

+ 90degs still seems like a lot

[cobraman302]

+ 90degs still seems like a lot

You are right it does sound like a lot, if you are uncomfortable with that I would go with the Kenne Bell specs and just torque to 7 ft lbs. For some reason KB specs the torque differently.....they leave out the 90* turn after 89 inch pounds. It's nerve racking stuff waiting for a bolt to snap.

Yeah, I'm going to stick to the 89 in-lb torque. I priced the bolt and it is 3.25 through Kerry Ford and there is a 2-3 day wait on it. Did you reuse your coolant line gasket or just replace it with rtv in the back of the supercharger?

[KenB]

Did you look over those welds really good? I know you probably look at alot of forums but if you haven't there have been alot of issues with that plate cracking at the welds after just a few thousand miles

[PKFIRE]

I have the latest revision on my blower. They replaced the .062" think aluminum with a heavier .125" thick plate and change their welding procedure. I had a couple of engineers look at it and also djom1cincy who is a welder by trade. I showed the engineers the initial design and the welds. I showed djom1cincy the blower in person. The engineers said that fluttering was causing the welds to break on the initial design and that this should hold. I feel more confident, if it goes south on me at any time I may just have the plate completely removed.

[cobraman302]

unfortunately you wont be able to tell if its cracked til its on the car for a bit, but I GUARANTEE it will crack, and that sucks. The way they weld cast to aluminum (the plate for stage 5's) the welds will crack easily. I really hope you have good luck with it though. Here are a few pics of what happens to them, and to my knowledge its happens to every single one sooner or later, just a bad design.

Sorry, didnt see that previous post, hope they have fixed their design. That thing should make some kickass power.

So what happens to the s/c or engine when those welds crack? Do parts end up in the engine and mess things up?

[PKFIRE]

the heat exchanger is place inbetween the lower intake and the blower. I know you don't want to get any kind of metal fragments inside the motor but at least if anything that there is a protective barrier between the plate and supercharger. As far as I know I haven't heard of the cracking issue causing motor failure.

[cobraman302]

Chunks can fall into the intercooler, and from there its a crapshoot it they end up getting through the intercooler and "possibly" into the heads. I haven't heard of this happening yet, but its obviously not good either way. There is a huge mess about Steg on SVTperfomance.com and modularfords.com and I will personally never deal with Steg again. If I were to get a blower ported it would be from Posi...makes better power too from what I have heard. He is located about 40 miles further down 71 past Kentucky Speedway. Here is his website http://www.posiperformance.com/index.php?option=com_content&view=article&id=56&Itemid=62 If I dont go Whipple this winter, I will be doing injectors, maf sensor and his race port with some weight reduction.

This what I meant to say,lol

[PKFIRE]

Got some work done over the weekend. I got my Blower installed, used 89in-lb torque on the lower intake manifolds = no broken bolts. Everything went together nicely on supercharger install. Today I worked on placing the x-pipe in and it was pita. I had to grind down bolts, buy bolts, and the far passenger side mount bolt on the exhaust manifold was tough to get out with the tools I had. I finally got it after trying 10 different combination of tools placed together. Thank god for liquid wrench and swivel sockets. I thought I would be able to do it in a hour,lol.

I had help from my brother also djom1cincy came by to pick a my stock M112 for future plans.

[djom1cincy]

Now get it to cincyspeed!

[PKFIRE]

Well I finished the car up Saturday by placing the last bolts in the exhaust and adding fluids. Started the car with the base tune and it fired right up. My wife was just hanging out with me near the car and puff of smoke stopped her from reading her book. After that the car ran clean. Off to Cincy Speed this Friday.

[djom1cincy]

Cool. How did it sound with the new x pipe? Can't wait for numbers.

[PKFIRE]

Sounds good, the car is way louder than I'm use to. I haven't tried driving it yet though.
I hope it puts down decent number, 500whp or more would be awesome. It doesn't help that it's going to be hot Friday.

Yeah that really sucks its going to be that hot out. Reminds me of when I had my Lightning dyno tuned at MD on THE hottest day of the entire year, just my luck. Hopefully you can get that 500+ RWHP you are shooting for. It will be close, I am crossing my fingers!

[replicobra]

good luck. that weld crack stuff is scary. i have had a stage 5+ on the L for over a year. daily driver that i am now trying to sell.

[PKFIRE]

Thanks, tomorrow is the day. I drove the car around today to get it ready for tomorrow and it's way louder. I'm not liking the rattles from the exhaust. I eventually have to find where the noise is coming from.

[djom1cincy]

Waiting on numbers!

[cobraman302]

Waiting..........

[PKFIRE]

Just got back from Cincy speed. Thanks Adam for your time and effort if you read this.

Well on the last heat soaked run, Get this run number 9

485.59WHP Torque kept dropping to 446 on that run.
Run conditions 95.00F 29.60in-HG Humidity 8%

[djom1cincy]

Your at 500 on a good day. Nice numbers.

[PKFIRE]

Your at 500 on a good day. Nice numbers.

I'll dyno it again in the future, I'm trying to decide if I should run the car tonight. I bought new plugs and I want to bend the x pipe from rubbing up against the car.

[djom1cincy]

You should. It will be cooler and the humidity is low. It's only goin to get hotter from now till fall.

[PKFIRE]

Ran 12.587@116.80 Last night with a 2.184 60' on the 555R Nittos. I say the blower gave me about 2 mph and .2 to .3 tenth of seconds. I miss my stock H pipe now since I can tell the car doesn't make boost as quick and I lost a bit of bottom end on the street. This might be blower related or the x-pipe is killing my bottom end. Maybe I need to save up from 2lb lower and a boost a pump.

Its def a combination of both. The more its ported the more bottom end torque it loses typically, and the off road X doesn't help. But its not all about boost, its about airflow. Edgewater has sucked ass lately and I won't go back anytime soon. You should go to Tri-State this Friday, I heard they are doing a test and tune event. What psi did you have the tires at? When I ran at edgewater the best I could muster was a 12.5 and went to tri-state and went 12.1 all because of the track prep. And I ran the same MPH as you, but I also have a 2lb lower and a BAP.

I've ran 11.9@118.3 with my Slicks at Tri-State and 12.5@116 with the Nittos before the port and x pipe. I had the tires set at 25psi then 20psi. Last night I wasn't going for a good 60' time as much as I wanted to see my mph numbers to go up. Since I'll make my best mph and time with the slicks when I plan to go back to race. Back to back I gain about 2mph with them vs the Nittos.

[cobraman302]

Good times man. I am shooting for 11.8X's on the drag radials and then maybe next year I will throw some slicks on it so its easier on the stock halfshafts. Sounds like you got a good 11.6 car in some good air.

I'm looking for 120mph at 11.5. I could of probably went 11.7 or 11.8 with my old set up but I'm worried about very high rpm launches. I bought the slick because of the same reason you said.

You may of said it but what kind of tires do you have again?

[cobraman302]

315-35-17 Mickey Thompson DR's. They are peeling pretty bad though. No way I can get the car to not wheel hop at the track, have to let out 9 times out of 10 about half way through 1st gear.

[PKFIRE]

Slicks= no wheel hop. Though your MT's are probably 100x better than the stock Goodyears.

[PKFIRE]

Bringing back an old thread, it is now fall and my idle issues with the Dragon have been solve by Adam at Cincy Speed and next Friday I'll see if the car goes 500whp SAE.

[Walter]

Why did you go with Dragon over an accufab unit?
