'99 J-spec twins--DEFINITELY!

 

I'll be getting my car dynoed sometime in the near future. Perhaps, that can shed some light on the low rpm HP debate. I won't be making 378RWHP like enuttage's car, but the RS/RZ twins are already spooled up by 2200rpm and at full boost on the primary by 2500rpm ... so perhaps we can get a sorta apples-to-apples comparison of the low rpm single turbo vs. twin turbo output. Of course, the 4th gear pull won't exactly translate to auto-x conventions; but we'll see how it does.

And, IMO, faster times (once driver skill gets to near equal level) is all about HP-weight ratios. That's why Miata's are so effective and Z06's dominate in many respective classes. I'm still chasing a fast little turbo'd Miata .... and he's a better driver than me. (Dammit.)

 

That should be corrected, as stated by the tuner, or unless I've lost all memory capacity.

Mods include GReddy SMIC, intake, dp, mp, catback, 850cc X 4, PFC and...well that's about all that matters that I can think of.

Let's see what RRR1's car can do. My curiousity is piqued. Where'd the 115 number come from anyway? Was it flywheel or rear wheels?

That little turbo miata is a bastard on the course from what I hear...

Hopefully I'll have an FD in the next month or so, and I'll have to see if you two (RRR1 and enuttage) can give me a ride. I think I'll stick to a street and road racing setup, but I'll probably autox once or twice.

Enuttage, you have the cool paint job, right? I was out there on Sunday just seeing what was up.

I make 16 psi by 3200 RPMS. And flow alot more CFM's than any smaller turbo spoolin the same boost at that RPM. I'm making boost at 2200 rpms. It comes on all at once. Much faster than my stock twins ever did. Its alot of money for the conversion. 99 spec twins are a good way to make some extra power and still upgrade without the huge expense of upgrading. Will also help you stay in your class.

 

i got 115 from a few stock dynoes inluding mine at 10 psi

so that 115 is at the wheels and seems right
that is SAE corrected

there are diffrent correction factors like sae std din eec and ucorected

i get 120 whp at 3k rpm with std correction thats why i was askign and your car i ssomewhat tuned on teh lean side so i am sure i can make same power if my car was tuned. i was just alittel surprised that u got that much with a single eventhough its a small single....

 

do u have a dyno chart boost is boost, but flow matters too so i rather see dyno numbers and like i said preferably in the SAE format so we can compare apples to apples...
