Hi Gays

I have GTO 2004 Bolt on
(ram air,ASP pully,MSD wire,spark pluge NGK,long tube headers,cat back,ratio 3.73,gear coolent)

i installed camshaft
Due int 227 Exh 227
Lif int .639 Exh .639
Lub 116

but it dident get good horse power only 21 hp with no change in torque
if any have an idea please feed me back

thanks

 

Did ya tune it? Why go with that cam?

 

Did you change the springs too? And pushrods?

 

nice way to start off.....

is this a A4 or M6? A4's will not see big gains like the M6 cars will. i only picked up 30rwhp with a TR 230/236 cam, but at the same time i have a 3200 stall so i didn't expect to see 40-50 hp gains.

 

i would think you would see a bit more than that . you running a 116 lsa ? have not seen many of those . throwing any codes ?
take it up to the track and see what kind of times .

 

Basically its not a huge cam, duration will often dictate gains and LS1 cyl heads often stall out @ .550" of lift, so all that extra cam lift means nothing until you get work done and then again when combined with a LS6 or even bigger, the CFM you push will only be so much.

I would have the car retuned, if it hasnt already, even with a 228/227 cam, it should have gained.

 

He should have gained much more than 20rwhp, stock heads do not "stall" at .050, The extra intake lift while not rational, acts as a crutch to get more intake charge in, this is a high reving cam, till 6800+ so midrange trq will suffer and the cure is higher compression.
Also is this cam straight up with no advance in grind, if so it needs ddegreing, because if not I would bet my socks that it is actualy retarded now and that is where part of the other 20rwhp went. Properly done that is a 40+rwhp cam
If on 116+0 that cam has around 49>50* IVC, way late for stock SCR/DCR, it is LSK Comp cam lobes, looks like TR grind.
To make it better, advance 4* (if no advance in grind) and add compression like a set of 5.3L ported

Look at my sig, that is a similar cam, look at the compression I'm running and the output.

 

Thanks gays for respound

I got this cam from thunder racing. so, i asked them about this and they said this cam well work very good with aftermarket heads and F.A.S.T intake.

so, gays if any one have experince about this please feed me back

thanks

 

Guys, this cam was designed for ETP or TF 215's with good intake and exhaust and 11:1 compression. We consistantly see 435-450 at the wheels through fairly large converters with this combo. The cam has 4 degrees of advance ground in and has VERY GOOD driveability. I do offer this cam on a 114 for less efficient cylinder heads.

Thanks,
Shane

 

Put the heads that it was designed for on and get a tune. You will love it for sure!

 

Whats up with the reference?
You from San Francisco???

 

Man learn to spell or shut the hell up. seriously the a and the u are pretty far apart bro, are you doing that on purpose cause if you are god help you.

PredatorZ how did you go about getting that compression ratio?
