I've been looking around and I can't seem to find any more then 1 or two 700bb dyno results on here. Lots have people have discussed their numbers but the curve is rarely shown - and the one I saw seemed like a bad tune, with a bad curve... not sure if this should have been here or the dyno/tune section.

Please share some if you can dig them up - thanks!

 

I don't have any graphs but I have driven a few, they pull early and hard. They spool about 500rpms after the 530bb kit does if I recall right.

 

That makes sense to me. The only graph I've been able to come across can be found at:https://g35driver.com/forums/forced-...o-numbers.html

It just seems to me that the 700 bb that they have there, seems to be a pretty late power curve... Is this just a tune issue? Or is this to be expected.. the 530's is completely different...

 

The area under the 530 curve shows it to be a good street application and it puts out more power until 4000rpm. If your racing and keeping it over 4000rpm the 700 would be the best bet but will also require other engine mods to support it. The JWT 530 kit can be used on a bone stock engine.

 

Thank you for the info. I'm buying a 700bb kit from another user as well as having a stage 2 ipp motor so I'll be good to go as far as other mods needed... I've also got a oil cooler, catch can and custom fuel return system for the setup as well so I don't see any foreseeable issues arising anytime soon. I was just trying to get an idea of what the curve will look like and didn't know if the picture above is typical of the kit.

 

Here's my graph. as you can see with the dropoff. limiting factor was the injectors at the time of the pull. (460cc) JWT BB700 kit. twin intercooler, garrett GT28RS .86 A/R turbos.

 

Thanks for getting this up here - I just need some clarification on what I'm reading though. Is this 2 separate runs, the left side showing the torque of run 1 and 2, and the right side showing the hp of the two runs? What was the boost for run 1 vs the boost levels that were final with the higher numbers? Much appreciated.

 

Yes. It's 2 pulls. 1st pull is 10psi and 2nd pull I believe is at 13 or 14psi. They wanted to charge me extra to put a sensor in my exhaust and I called bs but I def recall baseline being 10psi. (Boost controller reads each boost)

 

Makes sense to me.. What exhaust were you using? Did you ever get bigger injectors and tune all the way?

 

I was running a stillen true dual. Ended up goin with a GTM kit, bigger turbos, fuel system. The whole shebang haha.
