Dynoed my RB20DET today

Post by **Yellow4g63** » Tue Dec 14, 2004 3:29 pm

it was a nice cool Socali day today and I decided to get a base line dyno to see where the car is at before the mods a come flying on to the car. Stock boost,Intercooler no filter on maf and 3" exhaust all the way back It put down 184.5hp and 176lbs TQ with a semi cooled downed motor. 2nd pass was 186.4hp and 174lbs TQ Last run Sidemount already heated got a 183.3hp and 174lbs TQ. Stock boost 10psi I think. A/F was pretty good too. From 5.4 it was 12.1 and at 6k it started to richer at 11.8 stoped at 11.5.

Congrats! Nice to see some people getting on the rollers... what all do you have planned as far as upgrades?

So now we have 2 RB20's with dyno graphs (Hybrid's and yours) correct?

I think 4 so far. Frostedflakes and another guy that lives in Socali.

Next I might put the PFC on the car and make the base maps better. I'm still waiting on a intake manifold gasket so I can put on my intakemanifold after I redo it (going to buy another DIY kit and chalk this one up as a loss and make it right with real velocity stacks vs air horns). Flanges are been made for the exhaust manifold so I can put my turbo on. FMIC will go on the same time the intake manifold goes on. And when the turbo goes on the injectors will go in at the same time. I really don't know how much hp I will make but I going to prob run 16-17psi on pump and 25psi on race gas. I'm not a big fan of race gas tho so may just be pump only will have to see how it goes.

Do you have a graph for yours? It would be nice to see what the powerband looks like for the baseline pull.

How much for your intake manifold you'll be replacing?

Make me an offer. I hacking the flange off it to use so it wll just be what you saw in the pics that I have without the flange.

If you could send me pics again, and I'll think about it, if you want I could send you my lower intake manifold so you didn't have to cut this one off

Graph looks good! Why does the pull start at 4.4k?

Drop me an email so I don't hijack your thread too much, but I was curious which TB plate is has, if you wanted my lower intake manifold, and how much you'd want for this..thanks

Hey we have 91 pee water out here lol.

Were you running the RB front pipe and stock IC Carl?

Post by **Carl H** » Fri Dec 17, 2004 2:38 pm

indeed.running stock downpipe, turbo elbow as well as stock smic.the smic was pretty badly damaged as well, but didnt leak sooooo....the ic had its bottom 2 rows completely crushed so it was cooling but not well at all and im sure it created all kinds of turbulance in the intake track.

Stock boost on yours is 10 PSI? Mine never goes over 7 psi before the wastegate lets go. Pulls pretty good with just 7 psi tho.

Looks good, but the torque just goes all downhill?

Yup 10psi for me. I hooked up a Auto crapper boost gauge and checked it. Do you have a cat and stock exhaust?? I have a 3" downpipe and exhaust. no kat.
