It’s a automatic and it has cats. So the excuses start ;D
This car is a local friend of mine, decided to have jhm install the stage 1 supercharger when he was out in Ca. made the video for fun
Ok that’s good shit
A few questions.
- Which supercharged car was door to door with the stage 3 b5 jn the early part of the video? The jhm in house car? Or the other one?
- What is the modlist on that b5?
- What is the full modlist on the b6 that was at the strip?
- What was the car on the dyno… And what dyno was it?
Good stuff and thanks for sharing.
;D Thanks!
1200 cfm …that is like twice the cfm of the tvs1320!
Good stuff
Yeah. 443whp? I only dynoed 421whp and I’m a manual. Where’s my extra horses? lol
Headers possibly
- The race was between two jhm customer cars. The B5 guy and the B6 guy knew each other. There have been several Stage 3 B5 Vs B6/B7 Supercharger races. The best part is how well the B6/B7 can do on pump gas Vs the B5.
- B5 Stage 3 k04 25lbs of boost full 3" exhaust. I believe it was dual 3 to single 3.5. The B5 was on race gas the B6 was on pump gas.
- 2005 FI full exhaust with cats. Intake spacers and the JHM stage 1 blower.
- The car on the dyno was jays car. Keep in mind this is the finial tune. We detuned it from 482whp down to 443whp to keep the motor safe. This is the tune customers will be getting or already have.
Headers 
will get you 25 or better. Really helps the TQ out as well. In the tune, we worked hard to keep the TQ down, yet still give the car a very strong power curve.
Ok, headers. That makes sense. You think 443whp is safe though? I realize it’s Jay’s car now so you’re probably pushing the envelope. How much risk is it? You could probably push any B6/7 supercharged car to that level with the flip of a switch in the tune (with or without headers) but you haven’t. I’m guessing it’s just to be safe?
Watched that video a few times now, very cool! Is the tip transmission modified at all?
Thats fucken solid was I the only one that read 1.7 60ft thats momster for a auto csr…
Axle tq kills parts not really hp so low tq high hp is good…
Not sure it makes sense to get too caught up in dyno numbers and treating them like an absolute simple value that is applicable from one dyno to the next.
I think jhm have said the cars are comfortable below 450 whp and the corresponding torque values that produce those 450 whp. Once they pushed up to 475-480 is when they ran into lo gevity problems.
The best modlist of any b6/7 on earth produced 443 whp with that tune on the 034 dyno. That’s pretty solid and still safe.
I guess you may be thinking why not give me a tune that pushes a bit more boost to get me up to 443 whp or so since you don’t have the headers? Those last 20-40 whp are hps I would say you guys should be happy to leave on the table to maintain that margin of safety.
B5 was Jhm tuned? Or someone else?
Hehe, you know me, if I had the money today and stage 3 was readily available, I’d be jumping right on that 
Need more power…always need more power (not that I use it often, still haven’t even tried launch assist even though I’ve had it for 6 weeks lol).
AS you may know (but others may not), as it’s been explained to me, the reason they can crank up the hp a little bit with the headers is because they flow so much more thus removing heat from the cylinders (which is the known detriment to this motor with wall scouring etc). So they headers automatically give more torque due to the increased flow, and then it leaves a little more on the table to safely push the hp numbers up some while still leaving a safe headroom for everything else.
And chris nailed it, 1.7 60’ is pretty damn killer. I wonder what the LA S/C manuals are roughly cutting in the 60’ as the earlier versions of LA on na cars were only cutting mid 1.8-low1.9 from what I recall.
^^^I have seen a few low 1.8 60 foot times from launch assist equipped normally aspirated cars.
My car had a 1.82 I believe when I went 12.99 and at the dragstrip this year, I saw a boatload of 1.8 times out of boraVR6 and bangoman in their NA B6 and B7 S4s.
On the RS4 it looks pretty effective as well. George (2000S4) with the Misano Red RS4 cut a bunch of low 1.8 times and one 1.76 time.
That 12.38 is pretty solid for a modest modlist on a tip B6 S4 in the heat. Interesting to compare it to justincredible who went 12.27 @ 113 with a very fleshed out modlist that included headers and nitrous and a great catback. He ran that time in much better conditions though last fall. So I guess we can assume the supercharger car would have the edge in great conditions, but not by much. Nitrous is VERY effective.
I personally am a huge can of LA on the N/A cars…
Here is a link to my 60’ and 1/4mile times

Stock clutch, stock BBS COs, LA is one of the best parts of the JHM tune…thanks CV
wow your numbers are amazing
Run 1 1.80 60’ 13.19 103.96 (this was when I first got there, needed to get the first one out of the way)
Run 2 1.82 13.19 104.65
cooled down
Run 3 1.79 12.97 105.40
Run 4 1.79 12.92 106.43
Run 5 1.79 12.98 106.37
Run 6 1.95 13.41 104.93 (left my god damn ESP ON)
Run 7 1.78 12.86 106.56 (NEW personal best)
This video and launch information kills the automatics suck debate. >:( first the dsg now this…
I’d also like to support the synopsis made by sakimano. While it’s impressive to see the consistency of the two dyno results. Each dyno is so different it’s not a great yard stick if you ask me.
