Short of going and running my car on a dyno, I was just wondering if anyone could make an educated guess as to how much WHP I would have after having finished my I/H/E. I have a '96 Si with a '00 d16y8. I/H/E isn't anything spectacular, but I have:

- Bomz CAI with a K&N
- DC Sport ceramic header
- 2.25" in/out Magnaflow HF Cat
- 2.5" mandrel exhaust with straight through muffler

Wires are NGK OEM and plugs are NGK platinum.

I know stock I get about 127 hp at the crank, so I guess that would be maybe about 100-107 whp.

Any ideas?

Also, these are pretty basic mods, so I don't imagine that I need to run a higher octane than regular 87... right?

stock it's prolly more like 90 whp at 5800 rpms

With those upgrades it will prolly be around 100 whp at 5800-6000 rpms

I personally think that it's a waste of money to get higher grade gas with those mods. You can if youwant to,you might notice a little difference. But not worth the extra money in my opinion, unless your engine is pinging and/or knocking.

 

~105-110whp or so, really isn't much.

 

Don't buy higher octane than 87 unless you turbo or swap the motor, or run some really high compression, it's just a waste of cash

 

if it doesn't say you need premium gas, then don't use it unless u are running turbo. i agree with everyday getaway
