TVS 5.0 vs KB Cobra
A friend's brother just picked up the 5.0, so we wanted to see how it matches up with a local Terminator. ONly got 2 runs in, first one the 5.0 didn't leave right away since he doesn't street race much, 2nd was a clean start but he didn't want to run it up very high in the MPH.
5.0- 2.3L TVS, 10psi, flowmaster mufflers, pump gas, Drag Radials
Cobra- built motor, 2.6L Kenne Bell, E85, 21 psi, Drag Radials

Might want to look up the engineering and physics behind roots and twin screw blowers before making that claim.
Always silly to judge based upon one car. If the specs and mods are true that cobra should be sporting ~700RWHP easy. A car with belt slippage issues or driver issues doesn't give definition to all of the mods he has on his car. If the mods are true on this video then there are belt slippage or driver issues. The cobra has a superior blower with allegedly twice the boost. Even if KBs were garbage this race is still over based upon the boost. Keep in mind the 03 Cobra is giving up displacement, cylinder heads and RPM on this race.
A TVS 2.3L doesnt hold a candle to a 2.6L Gen II or III KB when it comes to HP/TQ pound for pound. Tons of dyno results out there to show this. Would be a much more fair comparison with a 2.1L or 2.4L Gen II KB.

Just got off the dyno
I have had all my dyno runs at the same dyno so here's your real world comparisons
Street tune 93 + 18* timing
2.9 standard inlet 3.5" pulley 18psi 666/572
2.3 whipple 2.75" 20psi 611/552
2.3 TVS 2.8" 18.5 psi 656/590
Race tune 104 or 109 + 19* timing
2.9 standard 682/601 3.2" pulley 21psi
2.9 crusher 710/620 3" pulley 21psi
2.3 TVS 681/642 2.6" pulley 21 psi
2.3 whipple 644/621 2.6" 24psi
Pretty apparent the TVS is a huge player now in the blower wars....thing is
Amazing.

copied and pasted just for you...even tho it's not a kb the whipple gives you an idea..

Were these runs done on the same vehicle, with the same exact mods in very similar DA and air temperatures? Anybody can just post **** like this. Where is the proof that this comparison was done properly? Same Vehicle, same mods, same DA same air temp. Otherwise its hogwash pulled out of the sky.
Gen II and III LC KBs are way different than whipples. Whipples are better than TVSs as well.
There is absolutely no opinion on this matter. Roots superchargers do not hold a candle to Twin-Screw blowers. Its not opinion. Lets start with the fact that roots blowers cant even sustain full boost throughout an entire RPM range. The typical isentropic efficiency of a roots blower is anywhere from 20% to 40% lower. The higher the boost the worse the roots blower gets. Wanna know what else gets worse? Heat. Roots cannot hang.
I'm assuming since these basic principles are not understood that I shouldnt get into much more detail on the topic for now.
Lets also keep in mind how often Cobra/GT500 owners switch to twin screw blowers and have since 03. Its called an upgrade. Theres a reason whipple and KB can charge the money they charge. If the alternatives were better I dont think they would be in business.

I'll start by humoring this.
