Here are some vids. The first two are it just getting put onto the dyno. It's not dramatic, but I just love seeing it moving around under it's own power.

Then, here's a very early tuning session on the dyno. This run goes to 4,000rpm or so and is only at 7psi. They're having to totally write the ECU map for this thing, so it takes a while.

I got some clarification today on the engine power. I had chosen in the beginning of the engine build to have a focus on minimizing turbo lag as long as it put 380-400hp down to the wheels. So, the turbo I got has a sweet spot in its efficiency range around 350 or so at the wheels. I'm really happy with this choice.

Here's a bit of cool info too. In a little dyno run like you see below (only at 7psi, but run up to 4,500rpm) it put over 200HP at the wheels. That means this engine is really going to have great midrange grunt. We're going to double (or a bit more) the psi as tuning goes on. I'm excited.

Tuning session is going well. This one, on 10psi, got 302rwhp.

Shortly thereafter (and while I was on the phone with them hearing this thing scream), it got 351rwhp at 14psi. The goal of 380-400 at high boost seems perfectly attainable.

 

Reinforcement to the engine? None, if you mean literal reinforcements to the block. We rebuilt the thing, top to bottom, to handle 26psi daily, but I want this car to be very quick, not just a dyno queen. So my goals were low lag with 380-400hp at the wheels on the higher boost setting of two. As you saw in the video above, we already got 351 at 14psi, and don't really expect to go much higher. These SR20s, when built correctly, can handle far much more than that. No block/cylinder reinforcement surgery needed at all.

Is that what you meant?

 

The car just did 421.90whp and 306.28ftlbs on 18psi! PUMP GAS!

It just did 431.44whp and 319.72ftlbs!

 

lol... I have to laugh because I remember this EXACT thing going on when my last project car was finally strapped to the dyno getting the standalone tuned... I kept getting phone calls or text telling me what is just put down and I kept relaying the info online like a giddy little school girl. I was soo excited as i'm sure you are.

Those are SOLID numbers on a SR20 with a fairly mild (no lag) turbo. I would think any bit more and the fun fast car is going to become the scary fast car!

 

Great numbers to be putting down! Congrats again!

I hope it's even more fun to drive than you imagined!

 

Great result. Exactly why I always want to smack people who suggest stuffing a heavy V8 in them.

So where are the burnout pics? Those stickers aren't going to come off the tires on their own.

 

Congrats sir.

Burnout vids? Well, gotta get the car put together first!
