I've ordered all the following does this look like it will be about 375rwhp which I'm shooting for? I saw one guy with same mods but a ported throttle body instead of a underdrive hit 402rwhp in a m6 on ls1tech.

2002 camaro z28 w/ 48k miles Automatic with intake exhaust put down 318rwhp 331rwtq untuned.

ASP underdrive pulley
tr224/224 .563/.563 114lsa
PAC beehives
magnaflow high flow 2.5inch 300 59956 cats
Mac midlength headers w/ offroad y-pipe
vettedoctors dyno tune

I'm thinking that would definately be worth 60rwhp, anyone agree. Thanks.
I'll post up the new numbers when it gets installed in a month or a year

 

With the dyno tune I'd expect they could make that happen As long as they know what they are doing. Good luck with it

 

Thanks, should I also get a ported throttle body for my next mod down the road, I've heard lots of times no hp gains with only boltons.

 

I think you'll get to 375, but I'd go with more cam.

 

I would think so with a good tune, and LTs.

But not if you have a stall.

 

Well, you've got an LS6 intake, which I'm not too familiar with, but I can't see the ported throttle body being a bad idea. Anything that helps air move in or out of an engine will give it a bit more power. I imagine the horsepower to dollar ratio will be minimal compared to saving up for an N2O kit later down the road for spontaneous fun. What kind of intake system do you have installed?

 

Depends on the dyno, tune, and conditions on the day it is dynoed. Those Mac mids will hold you back. I had them, carsound/magnaflow cats, LS6 intake, ported TB, but no UD pulley, and my car put down 368 w/a 226/226 grind.

If you don't hit your 375, don't sweat it. I've seen cars that dyno lower out run cars that dyno higher.

 

You should be very close with that cam. Get a 230/232ish intake cam and outrun MS4/Trex/Vindicator cars ALL DAY LONG. They never put enough gear/stall in these cars to run well not to mention they need to lighten them up.

??? Who reads anything out of a dyno with a converter unlocked? It means nothing. With the converter locked it doesn't matter if you have a stock converter or a 5500 converter. (well the lighter 9.5" converter will show a slight gain over a stock weight converter; but disregarding that...)

 

Thanks, I've gotten everything but the thunderracing order, It's been 15 days and they still haven't even shipped it out yet, the shipping department said the cam would come in 5 days ago. I don't want to go bigger on the cam though.

Also today I got my fiberglass SS spoiler, bought it off ebay from a spoiler company but since it only cost 220 shipped and painted I was worried about the quality and paint job but I can't tell the difference in the paint, it fit very nice, paint was flawless until I accidently dinged it into a chair.... and shipping packaging was great. only took 6 days from order to painting to recieving it. Nice LED light too.

 

Keep us posted on what you do make.

 

Sure will, BTW do the magnaflow/carsound 59956 cats have to face a certain way because I do not see any markings but I saw the random technologies cats have a side marked inlet.

 

They're not directional.

 

I threw my MAC midlengths in the garbage can after I couldn't even sell them for $200.

Get some cheap Pacesetter LTs.

 

Pacesetters are $395 shipped from Herron Performance

 

Kraest, I already bought them as I noted. I also ordered the TR224 cam too so don't recommend a F14. I wanted to stay close to legal as possible. I would of gotten american racing headers though if I went with longtubes since they are only located 20 miles from my house and by far the best headers.
