DTM Brian Posted November 5, 2009 Report Share Posted November 5, 2009 Another stock long block cobra with a Vortech Supercharger. Well we assume it is a stock long block. Car was purchased through an auction with the following modifcations. Vortech S Trim pullied for 13 psi Siemens 60's SCT BA2800 Maf Aeromotive A 1000 (Had to replace it today) Aeromotive Lines and Rails A number of suspension modifications. http://75.180.27.125:50001/Dyno%20Graphs%20and%20Pictures./Customer%20Cars/Brian%20Cheatwood/SDC10798.JPG Yes I am aware of the what happened to Chads cobra given the power it was making. Customer is aware that this pushing the limits of the stock long block. A new long block and supercharger head unit is going in over the winter and will be shooting for 700+ RWHP. Blue=On3 Turbo Kit Red= Vortech Supercharger Looks like the turbo car makes the same rwhp with 2 pounds less boost at the peaks. (9.5 vs 11.5). The Suprcharger Car made a peak of 13.5 psi at 6700 rpm's http://75.180.27.125:50001/Dyno%20Graphs%20and%20Pictures./Dyno%20Graphs/1999%20Cobra%20-%20Vortech%20vs%20Turbo.jpg Blue Lines=New Aeromotive A1000 Red Lines=Defective Aeromotive A1000 http://75.180.27.125:50001/Dyno%20Graphs%20and%20Pictures./Dyno%20Graphs/1999%20Cobra%20-%20Brian%20Cheatwood.jpg Quote Link to comment Share on other sites More sharing options...

Stimmel1647545512 Posted November 5, 2009 Report Share Posted November 5, 2009 Any idea how much power the car lost due to those hideous decals? Jesus christ people really? on a cobra even? cmon now... Quote Link to comment Share on other sites More sharing options...
AWW$HEEET Posted November 5, 2009 Report Share Posted November 5, 2009 im gonna have to go with stimmel here. i wonder if APC sells a sick body kit for that, would go great with the decals. Quote Link to comment Share on other sites More sharing options...

BDHG940 Posted November 6, 2009 Report Share Posted November 6, 2009 I think it will be pretty cool once my motor is done to do a pull at the same boost, 13.5 and overlay that :-) Quote Link to comment Share on other sites More sharing options...

DKilbourne Posted November 6, 2009 Report Share Posted November 6, 2009 Heres a random thought, what CFM does each produce? I'd rather know the amount of air moving and not the PSI at this point. Both seem to be doing a decent job of making power too. How about a rematch when both of these have built motors? That should be fun.

Both seem to be doing a decent job of making power too. How about a rematch when both of these have built motors? That should be fun. At this point, who really cares? Compare the AIT and call it a day. Compare the torque curves. If I were shopping between the two and saw that chart it would be a no-brainer. Do I want progressive power building to a peak, or do I want a flat torque curve with a broad powerband? Quote Link to comment Share on other sites More sharing options...
Dammit Charlie Posted November 6, 2009 Report Share Posted November 6, 2009 wow look at the tq difference though... I dont like the paint on teh red one at all... good numbers for sure though That's the first thing I noticed. Keep in mind that Vortechs don't make peak boost until stupid high in the rpm's. Depending on the size of the turbo, you can hit peak boost a lot lower in the RPM's compared to the vortech. Quote Link to comment Share on other sites More sharing options...

When you have non-driver A let off of the gas and take time to shift in the turbo car how long does it take to come back into boost? How about the same with the vortech car? We can do this all day. Bottom line is that both cars make good power and I personally would take the blower car. Too many turbo boys running around these days. I care because people are comparing boost #'s and not flow #'s. If the turbo is pushing more air through, then it will make more power with less boost. Both are fun, but I'll take the blower car with a bigger version of the vortech. Of course that's with a good bottom end. Quote Link to comment Share on other sites More sharing options...

That should be fun. that would depend on how one is pulled, and the other is gated... i mean really. and if the dyno graph showed maf voltage, and we knew that one is draw through and the other is blow thru, you could sit down and figure it out.

I do t really know what you are getting at but if you ever rode in one of my turbo cars it's always in full boost after a shift. The s/c car regardless will not be back to full boost again till redline. Also most any s/c mod motor car makes lower torque than hp. Another reason why I like the turbo route on them. My car made 440/396 on 8# and 9.4 now on the turbo making 150 more ft lbs on 1.4# of boost Quote Link to comment Share on other sites More sharing options...

My car made 440/396 on 8# and 9.4 now on the turbo making 150 more ft lbs on 1.4# of boost and thats how you vented the block there buddie. torque. to much can be a bad thing. and your rods said so! 4th gear is the true load on a motor. the super charger is going to be more linear in its power curve. hence being easier on the rods . but then what does turbo charging or super charging do to a engine? it moves more air into it. right! its not a apples to apples comparison. its apples and oranges. cause a turbo is not a super charger. they only share 1 thing in common, they move air. like take a 76mm turbo of your choice, custom impellers, a/r what ever. its not going to move the same amount of air as a f3 blower...or f2 for that matter. so if you wanna take a turbo and compare it to a super charger, compare the one thing they have in common. air flow.

I'm just saying that it seems like everyone and their brother is knocking blower cars lately and it makes me laugh. I would have liked to have ridden in your car before it blew to see how it felt in comparison to some of the other blower cars running around. I guess I'll have to wait for the built version of it Edited November 7, 2009 by DKilbourne Quote Link to comment Share on other sites More sharing options...
mitchsY2kGT Posted November 7, 2009 Report Share Posted November 7, 2009 (edited) I like my procharger blower!! Think n i may upgrade to a f series head unit and e85 it, think n i can get about 800 out of with that combo, i like turbo cars there cool, butt there is alot of people knocking blowers, its all in how you build your car!! here latley ive seen a few turbo cars not having to much luck!!

90gt Posted November 7, 2009 Report Share Posted November 7, 2009 Turbo cars from what I've seen always have impressive trap speed but don't et that well in stick cars anyway. I think I'll stick with a blower on mine for that reason. Quote Link to comment Share on other sites More sharing options...
