Bolton Mods and cam only RWHP?

[GMBOUND]

Great write-up Trukk,

[rangerrob]

Trukk,

Very impressed by the time and detail you took into answering my question. I appreciate it. Can't wait to see it and meet you at Summit Point in May.

:blush:

that's a shame about Tbyrne. They were great when I ordered my headers from them. If they are out of the picture, I wouldn't hesitate to recommend:

Byunspeed
New Era Performance
Texas Speed
Thunder Racing

I've ordered from all of them and had no issues. Byunspeed was extra good, as I had a couple of issues with products not being available, etc., and they were super about their communication which is always good.

Just an added note. I gained 70 rwhp on my LS2 with pretty much all the mods Trukk listed except underdriving the pulleys and a mild street tune (daily driver).

[peedeerooster]

Can you post your dyno sheet even though I have an LS6 with a few less cubes? Thanks

420/390 with cam and bolt-ons only here.

Excellent write-up trukk.

I only did the must-dos on your list with the exception of the ASP U/D pulley. It's relatively cheap and easy to do while you're in there that it almost falls in the must do category. Oh, and I ran the comp 918s for 6 months with no issues, but Comp swapped mine out for the 928s for free. I've had no problems with the beehive design and I am just over .600 lift.

Tom Byrne has $1300 of mine for a set of headers that I ordered. Seems old Tom wanted to hide some money and closed the doors overnight a few months ago. He owes a lot of people besides me money for things like Maggies that were never delivered.

Off with his head!



--------------------------------

Nice write up on the mods Chris - The new cam sounds interesting!

[blow03ss]

The LS6 guys can see about 415HP with bolt on's and cam and the LS2 guys will see about 435 with the same stuff. I had a 05 V with all the normal crap like SW LT's and Magnaflow CB Volant CAI and TQ2 cam and made 413 on a mustang dyno. The LS2 guys are seeing 20-40 more HP with the same mods. Just some facts that I have seen with my cars. I will post up my dyno results soon and compare the LS6 with the LS2, both motors will have the same mods and cam.

[peedeerooster]

I am getting the resonator from trukk. I have recieved the volant CAI. I have ordered Kooks longtubes and catless connection pipe. I am only about 6 hours from Vengeance Racing in Georgia. I am pretty sure I will just take it to them and see what they can do for it with the addition of a cam. Hell while I am feeling frisky might just slap a set of AFR 205's on it to see what it will do.

STOP!!!!!

Dont just slap on heads..You have LS6 heads which have 210cc intake runners, the AFR 205 are exactly that, 205cc intake runners...

If you are lookin to make serious power with a few bolt ons, go up on the intake runner size, not down, Yes theoritically you will "accelerate" the air and cool it further, gainin torque, but you loose Hp in the long run... Go with the AFR 225 heads with a nice cam and intake system...

You have an LS6 Not a little LS1. Ls1 guys go with 205 runners for they have 200cc intake runners..Its a nice power adder for them...

You have to ask yourself a few questions

1. Where do i want the power
A. Low
B. Mid
C. Top end
2. Application
a. Daily driver
b. Weekend warrior
c. straight liner

The options are endlss for you...

I am lookin for mid to top end power weekend warrior, I am going the NA route, I am stickin to the GM cam for the center has been bored out, saving weight, upgradin the Timin chain, lifters, and rocker arms for higher RPM revs. Not to mention increasin the Compression and air supply. I am lookin at north of 420hp and 400ftlb at the rear wheel.

The guys at Vengeance are top notch. Just let Ron know what you're looking to get out of the car and he'll set you up with the right cam. And Mike can tune the hell out of it, so you shouldn't have to worry about drivability and street manners either.

If you're gonna do heads and you don't mind shelling out the extra dough, I'd consider a set of Trickflow 215s. Or if you're just looking for an extra 20 or so hp bump for under a grand then throw a fast intake on there.

On it's way

I have spec'd all my mods towards AFR 205's as well.

I don't agree with this NAF. AFR's are amazing. They take the small runner theory to the max. They don't sacrifice low and mid flow numbers for up top gains. They are still very stout up top, but's it all about that overall power under the curve.

Compare the flow numbers between the AFR's and the other 'hogged-out' big runner dwesigns. There is not much difference, and you give up all the low and mig range TQ.

Why do you think PatrickG switched from AFR 225's to AFR 205's when he was doing his 500 rwhp N/A 346? THEY WORK AND ARE PROVEN.

It's not all about the size. Runner shape is what sets AFRs head and shoulders above stock castings. You have to do quiet a bit a porting to an LS6 to get flow number comparable to AFR 205s and by that time you've increased the volume way more.

Most shops porting heads have 230+cc intake ports on stock castings to match the high lift numbers of an AFR 205 and they're often still short on the low lifts. As you can imagine though the air speed is shot.

That is one area that most people don't think about, they will recommend a ported LS6 and say that AFR 225s (or the other large port premium castings) are too big. My point being that either head will work fine and neither are going to hurt you, it really just depends on what you want.

I went with 205s and a not so big cam (230/236) to help get my pig heavy Cadillac moving. In a lighter car or for more of a track oriented car it's probably best to go for the bigger setup.

[peedeerooster]

Guys I appreciate the input and I agree with some of you. The ported LS6 heads can't come even close to the area under the curve of the AFR's.

[peedeerooster]

Well, thought I would let you guys know what I decided. I gave Vengeance Racing a deposit yesterday to order all the parts. I have an appointment for May the 7th. I am doing a Volant CAI, ported 90MM throttlebody, Ported fast intake, Trickflow 215CC CNC heads, Yella terra roller rockers, hardened pushrods, VRX3 camshaft, ASP pulley, Kooks headers with catless connection pipes and a corsa resonator with h-pipe connected to the rest of the stock catback. I will let you guys know what she dynos after it is done. Anybody want to guess, because I will post the numbers. I will not be ashamed of what it does.
