4.6 2V Supercharger Questions ???

**Troll** · 01-29-2008, 07:57 PM

OK, now we're getting somewhere. Cabin Fever has pushed me completely over the edge already.

I'm kicking around the idea of a s/c for my '01 GT. I like to do my own work. I think I gots the mechanical skills to handle a kenne bell or vortech kit. There are only two things holding me back.

1: the fuel pump? I don't think I can lower my fuel tank in my garage and I'm just not comfortable fooling around with my gas tank. Also, how does a KB boost-a-pump work? I see what it says on their website, but still don't understand exactly. Does that mean I can keep my stock pump and just install the BAP? Is there enough fuel? etc. please explain!

2: TEH TUNE. If you read KB website they are real adamant that their tune is spot on and you don't need to do anything else. I don't trust that for shit. I work full-time +10+ hours a week and I really don't have time to take a day and drive (on a 1/2 whack tune) to Big Shot or SGS or Modular Depot. So, what do I do about that?

So, other than these two issues, are the nuts and bolts really that complicated as long as I take my time and follow the instructions?

Thanks All.

im sure you dont want to hear this but oh well

my advice is to upgrade the fuel pump. without the BAP. dropping the fuel tank isnt hard and can be done alone (but easier with help, just make sure you are low on fuel.)

if tuning is an issue i suggest buying a complete kit (includes proven dynotunes) from MPH in Georgia. check out www.modularpowerhouse.com

you could ride down to either stropes or strobes cant remember for sure, get it on the dyno and get a mail ordered tune that is just for your car and i am pretty sure you plug it in and your good to go.. I will get all details i am pretty sure this is how my buddy did it with his 04 cobra.

then, do I wait at Stropes until it comes in the mail, Scott?

j/k Scott.

I was at Stropes before with my other car. I'll go s/c-less if that's the only place left on earth to go. The old man treated me like a 4ucking idiot. I might be a 4ucking idiot, but if you're a business owner, you need to keep your mouth shut.

that Mongoose kit is a nice kit. no intercooler/aftercooler scares me a little bit, but seems like other people on that forum got many miles out of the stock short block with Tim's tune.

I'll prolly chicken out and have a professional install the whole deal either way.

Notice in the mongoose kit, it says "focus fuel pump". I hope he means "SVT" focus fuel pump.

Dropping the tank is not as hard as it might seem I have a tiny garage. SGS could you sell you a tuner and give you a tune that would allow for you to drive there safely as long as you didn't get in it.

I pushed 10 psi with no Intercooler for couple years on the stock shortblock. Then sold to a friend who still uses it. I can also give you a link for a intercooler set up for 300 shipped.

This is how I would do it. But the mongoose kits are great and Tims mail order tunes are great but still mail order tunes.

This is the bare bones for something reliable

Vortech tuner kit from muscle motors. --2500
42lb injectors & Lightning Maf from ebay- 400
Tuner/tune from local tuner----------------500
SVT Focus pump from randy stinchcomb----90
Powerpipe from mph -----------------------200
Iat sensor from me I have an extra---------10
----------------------------------------------------
---------------------------------------------3700 for a nice reliable dyno tuned set up.

I have been to Modular depot and SGS for tuning, and I prefer SGS.

The best would be to upgrade to 03/04 cobra tank (baffled) and pumps. If you want a cheaper alternative that will get you by, do twin focus pumps in your tank (unbaffled)(good to about 475rwhp IIRC). If you do 1 focus pump you're only good to approx. 400rwhp. One focus pump and one BAP is good to roughly 450rwhp. (FP duty cycle will be approx 90%) BAP's turn the FP faster to move more fuel. Instead of sending 12v to the pump it sends 16v IIRC. Because you're moving more fuel the pump doesn't have to spin as often so the duty cycle goes down.

.

I would only get a custom tune if it were my car. To try and save $400 on a $4k blower setup and $3k shortblock is ridiculous. The risk isn't worth the reward. Basically, if you don't trust mail order tunes and if you don't have the time to take a day to get a custom tune...you're SOL.

I would get setup with an Xcal 2 from Dave Guy @ SGS and have him put a baseline tune on it for your trip out there. Just stay out of the boost and you'll be fine.

I would definatley recommend upgrading the fuel pump itself rather just going boost-a-pump. I was in your same situation about 5 yrs ago when I first did the vortec install on my 02 gt. At that time I wasn’t really sure what I was getting myself into. I pretty much took one long weekend to do the complete install. I did it in my garage with a floor jack and stands. Dropping the tank really wasn’t all that bad, but it is easier with a helper. I had used the vortec mongoose kit from Modular Powerhouse. Their kits are complete and the tunes are excellent. Like Jared mentioned in a earlier post, I would also highly recommend going with a mongoose from MPH. They are available with the vortec or kb and you can get with or without the intercooler. My first kit was without but I later had the intercooler added. I know it’s a hard decision to decide what to go with. After owning both the vortec and kb I would recommend the kb. There is nothing wrong with either choice, but I found that since I don’t really go to the track and mostly just drive the car on the street, that the kb low end torque is a lot more fun than the high rpm boost of the vortec. I was impressed with my vortec until I had the kb. Now granted, when I went with the kb I also added a built motor, heads, and cams so it was a big jump in power, but I have always thought since doing all of this that I would have wished I would have came across the kb first. Again, this is just my opinion. I have nothing bad to say about the vortec. Had I kept it and not changed to the kb I probably wouldn’t see it the same.

thanks for all the ideas, peeps. I'm really leaning towards the Mongoose kit right now. that basic kit with no intercooler. I do like the low-end torque associated with the KB, but I really really really would rather deal with a built shortblock way later than way sooner (if ever). I know I'll be just like every other nutjob on here and think I'll be happy with 350-375RWHP at 9PSI, but I'm going to try that first and we'll go from there.

Why pay extra for tims kit when you can piece a kit together that has the same parts and get a dyno tune while you save 300-500?

No matter how good his canned tune is, I would still have it dyno tune which now puts his kit in the 4200 range. Also if he went to SGS his tuner would be 4 times closer. Because later you might want to mod some more or add some boost.

jive, right now troll doesnt have time or w/e to travel for a dynotune, therefore Tims mongoose kit seems to be right up trolls alley. he may pay a little more then piecing it together, but he is recieveing a tried and tested proven system, complete, nothing left to worry about.

**no1sirbutler** · 12-01-2008, 03:32 PM

Hey Troll I have a KB on my car and installed it myself. If you have any questions pm me.

**LaserPony** · 12-01-2008, 05:26 PM

Look at the new 5.0 Mag. They have a good article about a S/C in there you might like.

**wishIhada5.0** · 12-30-2008, 02:16 AM

I was looking in the new 5.0 mag about that tork tech kit...its a really nice kit but the KB 2.1L intercooled will cost less and make more power in the long run...no1sirbutler, how do you like your KB?

**no1sirbutler** · 12-30-2008, 05:16 PM

I love my kit. Very nice having full torque at 2000 rpms. Its a very complete kit w/ nice instructions. Plus there is nothing like a Kenne Bell whine.

**wishIhada5.0** · 01-02-2009, 02:39 AM

How does KB handle tuning? Do they send you a chip with a fairly safe tune on it? also, did you use the boost-a-pump or did you opt for the svt focus pump?

**Jivepepper** · 01-02-2009, 04:04 AM

I would always dyno tune. What if you had a faulty fuel pump?

**wishIhada5.0** · 01-03-2009, 01:32 AM

Thats what Im thinkin about the pump too. It seems much more reliable to me to buy a pump that is made to push the needed fuel rather than push something further than it was made to IMHO

**no1sirbutler** · 01-04-2009, 11:32 PM

They send a chip but i never used it. I had mine dyno tuned after the install. I also went w/ 03-04 cobra tank and pumps. Its a very good upgrade esp when you want to make more power. That way your covered w/ fuel and can always add the BAP
