Virtually Stock Dyno Results
Facts on the car:
1993 Lexus SC300 Coupe
5 Speed, 86,000 miles
Modifications:
Clutchnet 6 puck, Stage 3 Racing clutch (had 0.1 miles on it when we dynoed - just installed then dyno-ed)
Otherwise COMPLETELY STOCK
Results:
Dyno # 1
168.4 rwhp - 171.0 tq
Dyno # 2
170.9 rwhp - 169.0 tq
Air/Fuel Ratio is so rich it goes off the chart after 5,000 RPMs.
Graphs will be posted as soon as I get them scanned if anyone is interested.

Yes, unfortunately, we only got the clutch done today ... you know how it goes, you do more talking than working and end up wasting a whole day!
Anyways, Tuesday I get the exhaust done, so we will do a couple dyno runs with just the clutch and exhaust probably this weekend.
The next big project is obviously the head gasket, which we are planning two days on because the book says it pays 16 hrs, .... we will see.
Once the head gasket is done ... we are basically home free =) ... crossing fingers that everything will bolt up perfectly (right).
The only parts I am waiting on are:
HKS 3mm headgasket (yah, I know, I need it NOW)
ARP Head Studs
GReddy Profec B
Aeromotive Fuel Pressure Regular
AEM Computer (I still owe a few $ for this yet)
Other than that, I have it all ... turbo, intercooler, piping, dual fuel pumps, injectors, fittings, lines, wastegate, downpipe ... everything, laying on my floor... the list goes on and on...
Take a sneek preview

Will post dyno sheets soon, and will be posting more after I get the exhaust done.

That is really cool man. I feel so sad my baby is gone. I will wind up living vicariously through you i think. I have seen a few SC's around. But it is gonna have to wait for a little while. Keep up the good work bro.

SP63 w/ GReddy 3 row FMIC + lots of extras ;-)
awj, thanks man, I am sad also about your loss. I am just starting to get into this thing, and it would be nice to have a good comparison. I know what it is like to lose a car you love. Hopefully you find something else that can satisfy you the same again. Good luck, hope to see you in another SC.

Not too bad. My car dynoed 172 rwhp stock. I forgot what torque, I need to find that dyno sheet again. Nice collection of pictures. Wish you luck with the turbo! You'll be living my fantasy after the installation! Perhaps sometime I will be able to join the club.

168.4 rwhp - 171.0 tq
:eek:
Dat, that's a near 60hp loss from crank to the wheel. And it's a manual too (less loss than auto). I'm really surprised at those #'s. Don't the BMW 330ci put like 190hp to the wheels? Both are factory rated at 225hp.

Now, BMW 330CI is a manual if I am correct. Drive train loss for the automatic cars is around 20% while for manual is 15%. This is the reason why manual SC should dyno more.

The numbers seemed low to me as well, but I am not too concerned about it. The car hasn't been tuned up at all, I haven't even checked the plugs. I am sure that there are several little things I can do to raise the numbers a bit (surely not 20 rwhp, but some anyway), but I am not particularly worried about it until we get the whole project started.

DIrEctQL,
Yes, the 330ci 190hp #'s are for the 5spd. If your car did 177 rwhp and it's auto, that sounds about right. The 5spd should have a little more power than that even which makes Angel's #'s really low for me.
Take into account however, take BMW transmissions are very efficient and puts alot more power to the ground than one'd expect. It's able to take on head to head for example a G35 coupe whose hp is rated at 280.

There are many reasons why the dyno numbers are not as expected but it is good to see someone baselining a project. Now, when that puppy is cranking 400+rwhp he will know his hard earned/spent bucks went to good use
