Got behind a dsg cobra on I-12 just east of baton rouge on Monday. I followed him for a couple miles until we got out of traffic. Took off from about a 65 roll in 3rd. He got a little jump on me but I reeled him in through 3rd and 4th. We let off at about 140 and his nose was even with my door. Just got
my car out of the shop Saturday so this was my first race and I couldn't have asked for a better one. Guy I raced was pretty cool. His cobra was very nice, had tinted windows, Florida plates and some wide meats on the back. Looked like he may have had a DOD decal also. I'm hoping somebody knows him so I can find out what he had done to it.
nice but either he could not drive or was just playing with you. Sorry to say that but I hav ea few friends with modded Machs and when my 03 DSG was just stock they had a very hard time keeping up at that! NIce runs though and I didnt want to take the wind out of your sails but to even try to stay with a bone stock Teri you will need some good mods!

Read his sig man. He has a centri running 10 lbs of boost. I think he's a little far from stock.
EDIT
Slow on the post.

Well I have a centrifugal compressor on another vehicle, and although it makes 12 psi right before it shifts, at near redline. When it upshifts and the rpms come back down, I'm back around 5 psi, so yes my max boost and threfore max power is around redline and yes at that point the vehicle rips, but after the upshift, slug.
And comparing this Procharged 12 psi to my 11 psi eaton on my Lightning, wich covers a much, much broader rpm range, the Lightnings average power is much higher, and the Procharger is on a stock N/A motor with more compression as well, and there is no comparison.
Now if the op mentiones a positive displacement blower with the same boost, I would have guessed the Mach 1 would pull away with no problem.
I'm just basing this from my experience from centrifugal superchargers, they're great at redline but how much time is spent at redline even at full throttle?
Her's one more scenario, I floor my procharged 5.4 liter at say 35 and it downshifts into second gear, my rpms are at 3500- 4K and my boost is at 6 psi at best. I floor either my Lightning or 04 Cobra in any gear besides a complete bog rpm and I'm at full boost either vehicle, who wins this war???
Sorry, I own 1 centrifugal, and 2 eaton powered vehicles and the average power is damn weak compared to even these undersized Eatons, at redline rpms our centrifugal vehicle rips at 12 psi, but after the upshift and rpms are down around 4-4500rpms the boost is back down to around 5-6 psi, now if I floor my Lightning or my 04 Cobra wich both have small eatons sitting on top, I'm at full boost at any rpm above a bog, sorry but for me, our centrifugal vehicle is a slug and also makes the most boost out of the three supercharged vehicles we own, yes it's on a heavier truck, but none the less after you upshift that mach 1 you are not at redline or at max boost for more than half of a run.
I'm glad and surprised this guys mach 1 runs so well as I like them very much, I've just never experiences a centrifugal vehicle I was impressed with, and I'll be the first to admit I've never rode in or driven a boosted mach 1, but I would have had much more faith in his speed if he would have said 10 psi from a twin screw or an eaton swap.
Long story short, on our procharged f 150, during the 14-15 seconds to cover a standing 1/4 mile, I'm above 10 psi of boost 12 being max at redline for probably less than 5 seconds, yes a lighter vehicle with lower gears may use this type of power range more efficiently than a heavier truck, but boost is boost and our Lightning or 04 Cobra will be at or near full boost the entire time except when throttling off the line, this is how I see it, from my experience.
Oh and also the extra point of compression from the 5.4 N/A engine with the procharger wouldn't help it come close to average power of the Lightning wich has less MAX boost.

You also need to remember that his Mach has a 6-speed manual so upshifting may not drop the revs nearly as much as in your centrifugal blown vehicle. Centrifugals are more efficient than roots blowers and make a decent amount more top end power at the same boost so usually other than the original hit where the roots blower shines the centrifugal setup is going to outrun a similar roots setup as long as it can stay in the powerband. General rule of thumb is centrifugal may run faster at the track with the better top end, roots is more fun to drive on the street or at part throttle because of the low end.

Thats a nice Mach I. If you are hanging with him with those numbers you gave us I could only assume that the Termi was probably a 2.76/2.8 upper pulley,maybe a lower,full exhaust,Intake and tuned. Good possibility a ported blower with those mods. Anybody know the weight of a 03 Termi vs. a Mach I? Anyway could run and strong car. That thing rocks!

Again I'm glad the op's mach 1 runs good!
Wow. Ever wonder why more drag cars use centris over PD blowers?! With the right gearing the centri can run down the PD blown car, even making the same power. When you are at WOT and you shift your rpms dont fall back to 1000rpms. I know when I shift my rpms fall right back into my power band. You have to remember, the PD blowers horsepower still climbs just like a centri blower. Its the torque that is present in the early power band. But when the HP crosses the torque the HP becomes the dominate factor. The centri will make more peak HP at the same boost level because of its efficiency being better then the PD blower. With the right set up the centri will enter the powerband very fast(rear gear, trans, step up ratio, pulley combo) and will stay in its power band. Its the twin screw blowers that really start to level the field of efficiency between the two. The twin screw will still pull till redline and make power where the root screw will fall on its face.
This outcome is not surprising to me at all. Good kill OP.

sounds like your problem. Not most people experience. My procharger is well into boost at 3300 rpms and I do not lose the boost like you are talking about during a shift. I would take a centri over a roots style ever day of the week. If my boost was in full boost any earler it would be a waste of rubber.
Plus that termi he was running was not stock and he still ran him down
