TBSS Magna Charger Prelim Dyno Chart

The difference between a Mustang Dyno and DynoJet:
The Mustang dyno will give you your actual street HP- the power you are making on the street with weather, wind drag, parasitic loss, etc all factored in. The Mustang dyno actually puts a load on the vehicle when dynoing to simulate these situations..
A Dynojet dyno is all for glory numbers, it does not load the vehicle at all and gives you numbers that mean basically nothing but bragging rights.
Typically a Dynojet will show numbers 10-15% higher than a Mustang dyno

again, a Dyno is a measureing tool....and should be used as such. ANY dyno can have the load tables messed with, ANY dyno can give you the glory numbers. I NEVER look at peak power, I look for percentage of gain.

huh? The weight on the dyno sheet is for vehicle weight....

The whole reason Im debating this (for your and everyone's info) is I get tons of customers that come to my dyno for a before and after senario with their supercharged vehicles and are disgusted by the fact that they only made 40-50 more rwhp. All these manufacturers claim 100-120 bolt-on rwhp with their kits and I have yet to see an actual "bolt-on" kit make those numbers.. Of course when you fork out another $600 ontop of your $6000 supercharger kit to get it custom dyno-tuned, it may make a difference, but when manufacturers dont state that with their kits, it makes my customer extremely pissed. I'll belive the numbers when I see 3 or 4 of these kits making the same numbers with a "bolt-on" kit.

Stage III Aspirated
TchargedLS1TA, I see you have a Dyno. Did you run the TBSS in a before/after the Patriot stage III heads? Kinda curious how bad the big volume runners and valves were for the low end torque on a otherwise small cube stock LS2.

Not the greatest n/a.. Stock HP numbers were in the 300-305 range.. With the big cam and heads we were making about 360 at the wheels, while running out of fuel. I now have the 44lbs injectors and a Walbro in, still needs some tuning but Im hoping for close to the 500rwhp range on some squeeze. if that dont work, we may step down to some stage 2's or even some stock ported heads..
One of the advantages of having a dyno...

I'll tell you what really hurt my TQ was the stall converter.. We lost somewhere in the range of 40 ftlbs with just the converter swap. However we are still playing around with a good TQ Management setting as I would like to keep my baby 4L70 happy as long as possible..
