I guess I will grab my mechanical engineer friend and have him and I give it a good look over sometime to see what the issue really is.
I had to build a new pedal mount for mine. I made the mount taller to "adjust" for the slack in the cable.

Not my best work but it was my first ever weld.

I also omitted the pedal stop. Because of the thicker plate it bottoms out right at WOT. I also notched the bracket on the intake to fine tune the free play in the cable.

Edit: 84 cables are NLA otherwise I'd have a new one.

Thanks, Oddly enough, I found out about this issue while on the dyno. The difference seemed to be about 7-8hp at WOT.

LOVE that you started the pull down low. Over 300 RWTQ before 2500 RPM. NICE!


Tom, I thought the original claim was 30hp on a stock CFI engine? Doesn't matter. Obsolete debate at this point. Either way, the intake works.

I'd have went lower but 1700 rpm is a reasonable roll in in 4th... that's about 45 mph or so and about as low as I would get into it on the street realistically. The couple of times I have tried lower I get a little spark retard from very mild knocking...

Now, the ported intake has finally returned from the welder. Time to get grinding. I put the time in. I want to see what it'll do.

You are correct. We did say in the beginning that on a stock motor and it is a realistic number on said motor. As you can see, it does rather well on modded motor as well. My motor loves my intake and I can only hope that I stick the launch this winter and do at least a 11.99. If I do, I WILL be a VERY happy camper. It will prove that you can make a CFI motor run well if done correctly. My new rear license plate frame says...1982 corvette, 100% crossfire injection.

If you run an 11.9999999999....you will be the king **** of all CFI-dom. And I mean that as a total compliment. I'm rooting for you to pull it off.

Anyone who takes "CFI" all the way. These guys are doing what I failed to do...what I checked out and sold my car before I completed. I even had all the parts!!...400 roller cam, AFR heads, etc...and I sold it all. So, I root for anyone/everyone with CFI to carry that flag and show the unwitting....what CFI CAN do.

I’ve got a brand new big fat set of Zeknova slicks for the race car. I’d be open to you doing a skid with them.

Haha yeah me too
Couldn’t agree more about the CFI. These cars make easy horsepower with some fairly straight forward and reasonably priced upgrades. Heads, cam and intake has been the way to make a Chevy (well any engine) perform all of my life. Just a shame those renegades are so hard to get ay @Buccaneer . My car is a long way from being fast but at 270rwhp it’s a lot of fun and pretty reliable for a 38 year old car. I really don’t understand the haters actually I do, hate normally comes from ignorance.

I'd love to finally get to the track. I just wouldn't want to deal with all the idiots there. With Englishtown closed there is only 1 track and my understanding is its pretty crowded with more the cars and coffee guys partying than anything. Last I heard it was maybe 4 passes for 50$... I don't want to drive an hour for maybe 4 passes... seems like a waste of a night off.

RMR used to be worse; All day T&T's you'd get 3 passes, if you were lucky. If you were lucky.

Still, it was worth it; you're making memories, it's fun as hell, trying to exploit everything you and your car has to give, and it's a hard and fast, undebatable result. Unlike dynos, apps, etc, the trap tells the HP story like nothing else can, and the ET tells teh driver/set up story, like nothing else can.

I say, totally worth it. Go, don't worry about the goons, focus on your own car and driving, drive it like you want to break it.

With the dana 36 out back I'm trying to to yet lol.

But I get what you mean. Maybe tomorrow night. With a heat index near 110 I doubt anyone will be there. But I need to grab a helmet to run.

Greg...that's a very nice offer by you and Ben should take you up on it, well Ben? BTW Greg, if anyone wants to help find a foundry to pour Renegades again, let me know. Right now, that IS a huge issue at a cost that doesn't break the bank. PM me if you know of a place. Please do not tell me to go off shore though, it isn't gonna happen or Mexico.

For me, if I can get just one tire before this winter, I'm good to go and the track is only 12 miles from me. My next biggest concern at the moment is my Dana44. I really feel that if I can hook it, but too hard, stuff is gonna break. That means even more work. I did think about doing the cast iron diff upgrade, but changed my mind just because of the headache and cost to do the upgrade. I have ordered some parts from Tom's through for the *** end to help it out a bit, we shall see. Worse case scenario, I maybe tie Ben's best time? LOL

If you mean me, the 82 has a Dana44, but still not real strong like the 78/79 setup.

@Buccaneer what tire are you looking for? There is a local shop with some drag radials in stock by me... I can see if they have one you're looking for and if so get it sent your way if you'd like.
