Can't decide on cams

 

It's basically a stock engine. Start with the basics

 

Thanks. just want a larger cam profile than the itr to take advantage of the upped compression. Was thinking to go with either tuner 3's or bc spec 4

 

Ttt

 

so are you looking to make a peak high hp or a broader powerband?

I normally don't recommend itrs on more than 12:1 but thats pump 91-93 octane. with the e85 you will be able to run more timing. it will have a wicked powerband/area under the curve. I could easily see 150 ft lbs and I bet still make 200 whp. itr or maybe bc3+ for power at or below 8000 rpm. just my personal experience I just had an 82x89 mm vtec with itrs.power was good but timing was fuel/ knock limited. with the few more degrees e85 will let u run it will really help a lot

 

With those pistons you will be right at 12:1 static compression. IMO not enough compression or displacement for anything too aggressive. Tuner 3's or spec 4's are better suited for a 12:1+ 2L

 

I agree.. Stay with a Pro1/tuner 2, but no more aggressive than a Pro2

 

I personally think on a stock port head pro 2's may be a hair much even.

 

Tuner 2 are too small maybe I'll go with the pro 1 since they make good power and torque not just top end

 

Loved the setup you had here. Hopefully the numbers on this will be similar if not better 🤓

 

The difference between the Tuner2 and the Pro1 are simply the primary lobes. Both make very similar peak power, but the Pro1 has a slight advantage in torque curve for that displacement. Smoother VTEC transition with no seat-of-the-pants "VtEc just CRACKED, YO!!" with the Pro1 as with the Tuner2. That was the main reason for choosing that camshaft for "SHE".

That car is still running strong. The owner of "SHE" wants to turbocharge, now.
