Simple gain suggestions for n/a owners-
Figured I would make a list of things I have found that will increase horsepower for the n/a guys. I'm sure most already know these, and you guys can add onto it, this is just a start.
These are the gains I saw on our dyna-pack
1) Clutch fan removal, electric fan install. Hp gain of 8-12 rwhp.
2) (distributer guys only) upgrading to FC coils, and a MSD 6al for leading. 15 rwhp gain
3) Going to full synthetic in transmission, rear end. Havent re-verified gain, but est 2-4rwhp.
4) underdrive pulley kit. 5 rwhp (this was on a pretty small factory set already)
5) Switching to green air filter, with cold air source 4 rwhp gain over the k+N
6) (distributer guys only) Remove one spring off the weights, and cut the slots in trailing vaccum pot larger, to close up the trailing split to 4-5 degrees. 3-4rwhp in the center of powerband, 2-3rwhp gain at peak.

I think it was Aaron Cake's website (don't quote me on that) that said the E-fan is good for ~1hp, if it was even a measurable gain. If this is for the FC, then it's not a good idea to put even more load on the not-so-great electrical system.
If this is for an SA/FB, then I can't really give any input on that.

This was how I initally got to 206rwhp on the 13b-re engine. It is still using a FB distributer, and had a FC clutch fan. I have a easy 25+ dyno charts, to show the differences. It will take a little while to download. The only one not set in stone is the synthetics. As it could have been a variance in temperature ect. from one day to the next. Just putting MY personal experiences using a real dyno.

By the way Logan I got a stupid size check from my parents for Christmas. The 20B N/A might still be on the table for next spring.

Slightly faster acceleration but again nothing exciting. If this is all one can do because of financial reasons than yes by all means do these simple mods and enjoy your ride.
But I was never a true fan of 'bolt on' performance. We are all in the same n/a boat here so sharing ideas is the way to go with that said I didnt want to sound rude by calling the above mods "gimmicks" but really, if I said your car would be faster by removing your interior........ you get my point.

I hear ya...It also depends on what you are doing with your car. If you are racing and can find 2 more hp somewhere than you are going to do it. If like myself, you are building a street car, 10hp up or down doesn't really make that big of a difference in the grand scheme of things. I do like to see people who have access to dynos post what they get from different real world experiences. I myself have been very impressed with GtoRx7's work. Cheers to N/As. Have a great Christmas!!

What about pulling the sleeves out of the exhaust ports I keep hearing about? Isn't that bad for the engine? Also, I seem to have an occasional stumble around 3500, I have been hearing about loose grounds, i don't think that's the problem, I was thinking it may be related to my ports operating? Also, what about upgrading the smaller of the two coils? I hear that improves performance...have I been mislead? Thanks!

i just got done taking the 5th and 6th port sleeves and rods out of mine. it took me about 10 minutes once everything is apart. basically these sleeves stay closed until about 3800 rpms then they open. without this you will have worse lower torque and it will have a hard time cold starting. as well as lower gas mileage. my motor is streetported so i took them out. i closed up the holes in the manifold with a couple of dimes and used high temp atf. jb weld is recomended as well. if you dont want to completly take them out i suggest buying the inserts from pineapple racing. theres a video to show you how to install them. merry xmas

Wow, I don't get it. Logan has showed you what he did on his dyno. Not internet racer ****. You mean to tell me if you put on an electric fan and got more horsepower you would call that a gimmick. I will take all the gimmicks I can get. And who in the hell said any of this was in place of building and porting a solid motor. Have you seen his projects. Not what I would call a gimmick. You guys sound like your panties are a little tight.

Maybe you guys should be a little more open minded. Here is your charts. I had to go through seriously 20+ dynos of it, but it shows the differences. Enjoy. Remember that this car is my daily driver, so my effort on making it a super high horsepower car wasnt a priority. Keep posted guys, and I will get more serious now and try to break 220rwhp, and then post my "gimmicks and bullshit" how I got there too.

GtoRX7 - Keep the ideas coming. Each of us can decide which ones we want to try.
I'm deciding over the next month - of either staying with the N/A for a while, or either going the turbo route or V-8 swap, if I can figure out how to get thru DE inspections without too much hassle.

well, i know i need more of a life because of the amount of time i spend reading on this (and other) forums, but maybe some of you need to spend more time, too. you need to lighten up a bit. everything GtoRx7 has been backed up with dyno sheets already - some of those things have been "dyno-proven" for about 10 years now. besides, not to say it makes him "God", but i haven't seen any of the skeptics in this thread build anything near to what he has. honestly, that sounded a lot more harsh than i meant it, but i'm just saying he's probably not one of the guys that gonna post something just to increase his post count. this thread has merit.

This might be a silly question, but I'll ask anyway. Suppose he does reach 210 or even 220 to the wheels. Would this mean that big bridgeports can lay around 260 to the wheels as well?
