depending on how much cheaper the other turbo is i'm sure its probably worth it. cuz it sure does seem to be able to make a very similar graph.

VE on the 2 turbo's was nearly identical with the exception of having to add more fuel over all on the S366. the shape of the curve didnt change


unfortunately with wheel spin, it has a tendency to give a false shape to the dyno chart.


we will be throwing some cams in the car shortly to see if we can get the power to carry out up top any more (which it pretty much has to). part of the drop in power up top is the distributor showing its age.

the msd box on this car is right next to the ECU so i was having a hell of a time getting any worth while logs. i'll have to look through them and see if there is anyting worth posting. i was having better luck getting logs by not logging through the laptop, and pulling the internal logs. i have a tendency to forget to save them when i do that

im actually very excited to see how your car does on the little tire. i know you guys will be just as fast if not faster than everybody else even with all the rules against you!

Thanks Joe! Cant wait for the track to open now to test it out, and then start trying to get it to hook on radials Thanks Bullseye and Tempest for a sick turbo

about $500 difference

Looks to me as if the garrett has the overall stronger power curve out of the two.

But I guess if you want to make 28 more horsepower for just less than a 1000rpms and have it fall on its face afterward while loosing 15 ft lbs of torque then cheers!

</TD></TR></TABLE>

Thats what sort of turned me off, when did it reach full boost by? and how much boost was it?

96 GSR-T

I might be missing the point here, but I would rather have an engine that made 775whp for 1k rpm over an engine that made 810 for only 300rpm, and the Garrett made more torque and carried it for longer, I would like to see a test with no wheelspin, odd how the Garrett made 50whp 25-30ish TQ over the Borg at 6500rpm but didnt spin the tires. Good test though

The point was to make the switch to a powerstreet legal turbo. Making more power over the 42r was just a bonus.

Mazworx

What exhaust housing where you using on the 42R?

Turbo-charged

man, im glad to see most people dont read. this turbo made more power and is 3mm smaller than the 42.


this turbo is designed to make good power, but legal for certain class's that have a 67mm turbo limit. last i checked drag racing wasnt a spool up contest haha. either way, when the car isnt spinning, spool up was pretty much identical.

the 42 was a 1.15 i beleive--i'll double check and post back

Matt2352

The way the rules read to me. The turbo limmit in power street is 66.5mm diameter at the leading edge of the wheel. Isn't the s368 67.xx?

Turbo-charged

we will be confirming everything on monday with nopi/nhra. if the turbo needs some slight adjustments to be with in the rules, im sure bullseye will do that and im willing to bet there will be nearly no difference in power output.

its pretty clear that their turbo's will make sick power

Matt2352

Thats great lets us know. I was planning on getting the 366 but if the 368 is legal I would be stupid not to get it.

Turbo-charged

here is the 42 and the s68 over layed at spring pressure, 0% duty cycle on the boost control. 10psi spring. no spinning should give you guys a better comparison on the spool up/power band.




and again, the power drop up top is a slight miss due to the distributor taking a dump.

DJsilkyjr

thanks for the testing joe, can you pm me a price on this particular bulls eye turbo and a nice manifold topmount for a b series?

So no exact numbers on the borg? Exd, Ind, A\R??

I think that shows the difference.

only if the logs show they were both really making 10psi on that 10psi spring

yes the 42r is a 1.15

thats crazy power for such a simple motor setup whats the plan for the ignition? was it a stock dizzy with the msd box?

After every pull we recorded the power, boost level, and duty cycle on the boost controller. The S368 made more power at every boost level over the 42r and as you can see on the lower boost dynograph [without wheelspin] it has an identical powerband.

yes stock distributor with msd box

SPOOLINmatt

can you get that s368 without that crazy compressor housing? maybe a housing more like the s366?

DaveF

Thanks Joe (and crew) for posting up your results. i was weary when you posted the 1st charts, but them 10 psi charts tell a differant story.

Tempest Racing !


btw, did that turd jeff, have his tripod out
