STIEGMEIER Stage 4 port WHO HAS ONE??

[03slidewayzSVT]

I just ordered my Stiegmeier stage 4 ported blower yesterday and ordered my 60LB injectors today.. MY question is who has one and what are the HP & TQ numbers your at??? with all your mod's done.. I my self would like over 550++ rwhp without the NOS and well over 600 HP with NOS I'm just wondering what combination I need????? Thank for all your help....

I just had a stage 4 installed not 3 weeks ago, and just had it tuned monday before last, please look at my mod list for my mods as its a very long list,

with LT headers, a 2,76 pulley on the stage 4, Accufab single blade, Mac cold air sys, I got 511.9 RWHP and 467.7 RWTQ , Stiegemeier says you can just bolt it on without a tune and it works fine,,,

Well it does, they are a very good company to deal with, good reputation also,,,,,,,but I did not get these HP&TQ numbers until I got tuned, and it needed the tune, ,,before the stage 4 I had a little more TQ than HP, in fact i had 485 Lbs torque and I lost torque but gained a lot more HP what happens the torque gets it moving quick the HP takes over so much that my IRS does that
"Not Knowing which wheel to keep sending power to" kind of side to side thing, like the tires at high speed start wanting to break loose.

well I'm getting a 4LB lower ordered tomorrow Plus 511 hp just won't cut it... right now I'm at 485/503.. they say 50+ rwhp so atleast 535 rwhp....

[Dave B.]

What do you have before the stage 4 to get those numbers you just put up last??

[Dave B.]

Ok, im just surprized you got 503 RWTQ, thats a lot, after you put on the Stage 4 will you loose about 12 lbs torque, but the HP you gain is going to make it feel much stronger, but your doing the right thing for sure by putting on a lower, as that gets back the torque lost in the port, now are you having to have higher capacity fuel pumps installed in order to use the lower???
the guy that tuned mind will not put a lower on after an 03-04 has hit the 500 RWHP mark without installing the better pumps too,

Dave B.

After you get around the 500+rwhp mark you will need either a KB BAP or larger pumps, you will also need a SCT meter. I recommend the 4lb lower and larger fuel pumps

[03slidewayzSVT]

all right My pumps are far from been used up so don't worry about that and I have a SCT2400 meter coming too I just want to Know what combinatons people have on their car's

[03slidewayzSVT]

Well I just ordered my 4LB lower from billetflow today no worry's about TQ loss now and the UPS man just dropped off my 60LB injectors a few minute's ago

[Dave B.]

Your going to use 60lbs injectors with OEM pumps?

[blk04cobra1]

He will mostly likely save the 60's for when he sprays, down the road

[03slidewayzSVT]

yes I'm going to use the 60LB injectors with the stock pumps for now and if I need new pumps I will buy them.... Forget about the pumps I want to know about pulley combo's with what CAI and exhaust for well over 500+ rwhp.

[mkkrs1]

who'd you order the injectors from and did they come with the harness. Are you doing the core exchange on the steggy or you planning to keep the stocker.

[03slidewayzSVT]

mkkrs1, I ordered my injectors from RPM outlet with the harness, Yes I did the core exchange.. PS you drive the white cobra right?????

[Dave B.]

Wow, the guy in Tampa that did my last tune said NO ,, NO WAY using my OEM pumps for absolutly anymore than what I have now, 500 HP is the limit and its not safe period to go anymore that 500 without upgrading,
So please let us know how your tune turns out using OEM pumps with a lower set up like your going to have,

Rob at PRO-DYNO has an 03 cobra with 530/560 RWHP/RWTQ with stock 39 LB injectors and pumps with no problems
