Thread: Dutch SR20VE dyno'ed - your opinions

I got the following result from a UK Dyno Dynamics rollingsession:

193.4 HP (flywheel) / 151 ft/lbs torque (208 nm)

With the following engine:

SR20VE with base igintion 5 degree
Franklin N1 replica cams (they are a bit more aggresive then real N1's)
2.5 inch SS header
2.5 inch exhaustline
2.25 inch muffler
NGK BKR7 plugs
Greddy E-Manage Blue

Max rev = 8200 rpm

VVL switchoverpoint approx. at 5200 int / 5300 exh

I found it a bit disappointing. The guy told me a seperate VVL controller for moving the points would be nice, also a set of adjustable cam gears to make more advantage of the cams which on the high lobes are 288 degrees with 11.5mm lift.

Wat do you guys think? Will cam gears help? Will moving the VVL points higher help? Would 200 hp be possible?

If you are disappointed with that, you are hard to please.

You have to run hotter plugs like heat range number five not 7's. Where did the motor peak power and where is the timing on the high end at.

@Viprdude:

Without the 2.5 exhaustline and stock VE cams it made 187 flywheel.
So thats not a big gain.

@gio: What would be the benefit of the grade 5 plug? Peak power is around 7400 rpm. Don't know timing right now.

Stock SR20VE base timing is 5 degrees.

I don't really get the 2.25" muffler... Why have a 2.5 header and mid-pipe, when you use a 2.25" muffler?

And almost 200 HP is nothing to be ashamed of.

Ben, I think he means base timing :P.

EDIT: And yes, a seperate VVL controller is always better, adjustment FTMFW!

Just my opinion

Get real n1 cams
Get 3 inch exhaust.
Get 3 inch muffler. ( You have 2.25 muffler, exhaust is only as good as its smallest point )
get 5-6 plugs ( plugs are to cold )

Now, if the car is making 193 Flywheel horse power that is not even close to being good. If it is 193 wheel horse power figures it is not to bad. 193 flywheel horse power is about 173 WHP.

I learn something new every day.

Thnx for the info Andreas
I thought the gasses cool down along the way so 2.25 inch isnt that bad.

And would a grade 6 plug make more power or is that something for improving reliability?
