SC61 Stock LS Dyno
1995 Ls shortblock
1989 Ls head
Completely stock internals
Pump gas 93 octane
GE blockguard
Greddy 660cc injectors
Hondata S100
2.5" downpipe
3" thermal exhaust
Precision SC61
This run was done at 14 psi. We kept it real conservative because this is a daily driven vehicle. We could have pushed it more...but the owner of the car was very happy with the results at 14 psi so we stopped there.

Re: SC61 Stock LS Dyno (drunkenbabyseal)
I think it was a mistype, man those numbers are freakin awesome, i'm really leaning towards the precision SC61, who has the best prices on them? Thanks

Re: SC61 Stock LS Dyno (94goldjungsr)
what? the graphs are almost identical... it may look like torque on my graph falls off faster..but thats just because the scale on my graph is stretched to 300 his stops at 275.

Yeah it is, for a turbo that will do twice that much power to the wheels. When you think about it, lagging to 5500 RPM's isn't that huge in the grand scheme of things. Slap that turbo on a B18C1 and spin it to 9000 and you have a pretty damn broad powercurve.

Re: SC61 Stock LS Dyno (Willis)
hmm... try configuring it so you have the same scale on the graph cause that dyno plot looks funky (because of the graph), but smooth.

Re: SC61 Stock LS Dyno (boosted92)
very nice. much nicer than that other one.
stil needs a better head though
(to hold the torque longer)
5500 spool...a little high on an ls imo but im sure it rocks!
0.63 a/r, right?

whats nicer about this graph than mine? they are almost exactly the same...like i said the scale on my graph goes higher so it makes it look different.
I was actually surprised with the SC61...I was expecting it to lag big time but it actually spools real nice.

I am very local to this shop. This is a little OT, but how much do you guys charge to install some suspension goodies (TEIN SS)? PM me.

why is honda-tech obsessed with low boost/high hp? who cares?

Re: SC61 Stock LS Dyno (Mpir3)
I agree, low boost, high boost, doesn't matter. What matters is what it runs at the track. However, if u make good #'s at low boost it shows that there is still alot of potential left in the set up..
Good #'s for both of you guys.. 300whp on stock LS motors makes me

Re: SC61 Stock LS Dyno (DIRep972)
but with stock internals you really only can push it so far...Isn't it better with stock internals to run really conservative timing, yes you won't make as much power per lb of boost but it will reduce clylinder pressures (at the expense of higher egt's) and allow you turn up the boost, basically let the turbo do the work..

I agree...let the turbo make the power. Basically, people have to realize that there are limits to everything.
The main concern with too much retard is high thermal stress which can damage pistons, plugs,etc quickly. so..by being conservative with ignition timing while keeping your egts in a safe range and staying within the hp limits of your particular engine setup, you'll avoid melting or cracking anything and have a pretty reliable engine no matter how much boost you're running.

Re: SC61 Stock LS Dyno (Willis)
Was there any particular reason he went with SC61? Going to build the motor further down the track or something? Seems far to big for a stock LS engine. Other then that nice work

Re: SC61 Stock LS Dyno (Willis)
you torque drops very quickly and goes from 271 to almost 200 while his holds a little more at 266 and stays to just above 225. thats why i like his better.
