A bit of a "dyno history" of my car (Plenty of video content inside)

So, I decided to post, in order, all the videos I have of my car on the dyno. Kind of a time line of my car's evolution in terms of power plants.

So, let's begin, shall we.

Here we are, in August of 2008, at the Fall Honda Meet I put together in Fredericksburg, VA.
This was with the LS which had just an intake, Crower 402 cams, and Greddy SP2 exhaust system.

Pull 3:

Best overall pull was 123whp and 114ft lbs of torque.

Now, for a tired, old LS with well over 200,000 miles on it, that's not bad.

A few motor plans came and went, but I ended up settling on a JDM B18C swap (SIR-G Spec, with the LSD trans)
So, let's fast forward to 2011, I swapped in the B18C and had fun with it, being mostly stock, just the basic I/H/E combo. A few months ago, since I knew I was going to be building the head, I decided to get a baseline of the motor as it was, so off to CNC Engine Dynamics for some glory pulls.

Here we go.
Pull 1:

Pull 3:

In this stock, bolt-on equipped form, I laid down a respectable 151whp and 113ft lbs trq
Not too bad, if I might say so, myself.

Now, let's get down to the good stuff. Let's jump ahead to last weekend. :)
I installed a set of JDM ITR cams and valve springs, as well as a first gen Skunk2 Intake Manifold (kind of converting the head to Type-R specs, but still utilizing the P72 GS-R head). So, I went in this past Wednesday for a tuning session with Chris Miller @ CNC Engine Dynamics.

Here's what we came up with.

Pull 1:

Pull 2:

Pull 3:
http://www.youtube.com/watch?v=96sL1_OhAJc&list=UUY58ECCCoPqBLMhBowgHoXQ&index=1&feature=plcp

Now, I have to say, that my phone's battery died after the third pull, but there were about 8-10 pulls in total, that ended up with a final number of 171whp and 128ft lbs of torque

So, to recap. With those numbers, that puts me at a 20whp and 15ft lbs of torque improvement over the stock B18C specs, and nearly a 50whp improvement over the LS when it was dyno'd in 2008.

I'd like to think I've got a fun little motor here ;)

As always, opinions welcomed. Thanks for reading and watching :)

Love the progression :)
How'd you like the 402's? I'm considering some 403's myself.
Love your car btw :)

I've heard the 402s are kinda weak. Some people say just go with 403s they offer more power; 402s are more mid ranged oriented.

402s are pretty mild. Not much more aggressive than the b18b1 cams. They didn't require valve train upgrades, which was a big selling point for me at the time. 403s are a little more serious, and do require at least stiffer valve springs. 404s, though, are no joke.


It's apples to oranges, now, though. If I had another LS, I'd just leave it be. They are hard to get serious numbers out of in NA form, and even when you do start pulling good numbers, the LS maxes out around a B18C's mid ground. Meaning, for a fraction of the work/money, you could the same (or better) results with a VTEC B-series.

Boosting, on the other hand...

As mentioned, boosted LS motors are pretty decent. I've seen stock LS motors boosted to around 250-300whp with just mild effort to reinforce the motors.

My engine build specs are pretty much as follows.

With the LS, it was just basic bolt ons, plus a chipped ECU, and the Crower 402s.

With the B18C, it's a LITTLE more elaborate, but still a mild motor.

JDM B18C (SiR-G spec with LSD trans)
3" Short Ram intake with 6" velocity stack and filter.
4-1 header with 2.5" collector
2.5" Vibrant High Flow cat (NOT a test pipe, a functional cat)
GReddy SP2 exhaust system
JDM Integra Type-R cams (98+spec)
JDM ITR valve springs/retainers, etc.
First gen Skunk2 Intake Manifold (I wanted the OEM looking "non branded" look)
Tuned on Hondata s300 Version 2

I'm currently using the stock GS-R throttle body, but there is a possibility that I might be picking up an OEM ITR throttle body/cable/cable bracket, and having the throttle body bored out by maxbore (would go from a 70mm tapered opening to 65mm).
