I Tuned It My Self :) OLSD
Still work needed to be done for max torque from 3700 to 4500 rpm, im still happy to dyno tune the first time :D.

What is it in SAE? No one uses DIN (outside of Germany).

467/1.0139=460.59 Is what it should be in SAE.

Evidently they had it setup that way in his country (UAE?)

Nice result OP. Seeing those heads you have, I bet you can get a little more out of it. Do you know what they flow?

Looks like you found one more place other than Germany that uses DIN. You also answered your own question.:engarde:





J/K giving you a hard time.:angel:

Very impressive results. Most impressed with the torque numbers. Did you have to flycut?

Its my first time dyno tuning, next time ill be sure to tell him to use SAE correct.

Thanks, Kuwait actually.

Ill try to find my head flow sheet, ill post when i find it.

Thanks, there is still some work left to figure out the dip from 3700-4500 rpm.

No flycut.

NICE.. I wish 215 heads were out when i had my first build..

Its TFS TEA 215 just to clear.

Wow, beautiful numbers just beautiful. Any plans for some 1 7/8th's and a UD pulley?

Slp UD pully allready installed (ill add it to the list in the first post)

1 7/8 headers...... NEVER on a 5.7L

Maby an upgrade to 102/102 somtime down the road.

^ So you believe your not leaving any power on the table by not running 1 7/8th's with your setup?

1 7/8 not at all, 102/102 probably :D

Btw guys all work was done at home and it was tuned by me :)

Ill post pics of the engine bay if i get the chance to wash it, i have parts powder coated yaaay.

damn good numbers. Nice job.

Have you personally tested it?

Have you personally tested it?

No never tested it.

very nice... i just got my heads for tea today.. i really want to prove people wrong about the 450 mark... everyone is telling me just over 400

this gives me hope

No never tested it.

You should give it a shot, i see tons of people picking up power with 1 7/8. Shit, I know all motor honda's that run a 1 7/8 header LOL. In no way is that too big for a 5.7l

1 7/8" headers...4 into 1 all the way and never look back for an LS motor.

Have no idea where Engine_HP is getting his info from....But he's way wrong!

You need 1 7/8 headers, you ARE leaving power on the table. I picked up huge on a stock LS1, HP and TQ, you just need to tune it properly. Ever wonder why most high end shops don't use small tubes any more?

I don't know what power levels this holds true up to but it's interesting.

In the back to back testing we did, heads with 1.55" exhaust valves MADE MORE POWER EVERYWHERE WITH 1 7/8" HEADERS COMPARED TO 1 3/4"

Heads with 1.57" valves seemed to make about the same power either way.

The AFR heads with 1.60" valves made less power with Kooks 1 7/8" headers compared to Hooker 1 3/4" with a cam that had 2 degree split.

So in my humble opinion, his headers were helping his stock heads, but worked against the AFR heads.


Thread where someone lost power with 1 7/8.....http://ls1tech.com/forums/generation-iv-external-engine/1498337-1-3-4-headers-vs-1-7-8-headers-my-experience.html

The 1 7/8ths will make a little more power but I dont think its necessary. TSP did a dyno on a stock motor (yes I realize his is built) but it should be atleast similiar http://ls1tech.com/forums/generation-iv-internal-engine/981234-stock-motor-1-3-4-vs-1-7-8-engine-dyno-results.html in this thread tsp gaines around 8hp and 8lb ft of torque on the engine dyno. If this was a car being dynod at the wheels youd be lucky to see an additional 5hp. Hardly worth the extra money if you already have headers. I could piss next to a dyno and make it spit out a number 5-10hp different lol. If your getting headers for the first time then why not but I dont think you need the... I agree with the OP do a 102mm lol.

^ They tested pacesetters against their own headers which just tells me theirs are a superior design. To get a more accurate comparison of the two sizes the same brand header needs to be used.

arguing that point is pretty moot seeing as most of the header designs today take most of their design ques from the Grotoyohan headers from years back. pretty much every header will dyno within a few hp of each other. you pay for the quality and material, its not like you miss out on 10hp when going from kooks to pacesetters. but just to further prove the point this is a comparison done with a stock ls3 camaro using 1 3/4, 1 7/8, and 2" headers. again the dyne results are all within 8hp or 8 ft lbs of torque... that is such a small minute difference its not worth it for someone to swap it ll out.

according to the logic that says a motor that moves more air will benefit more than a smaller one says that an ls3 should actually gain more hp with larger primaries than an ls1. again OP i say go with the 102, its about the same price and I'm willing to be you'll pic up a good chunk of hp.

This perception of header tube size has caused me to do a little homework as well as purchase a software to muddy up the waters a bit more. There is far more to it than tube size............ tube lengths, collector size & lengths, H & X locations as well as total length to atmosphere.

One very interesting bit of learn'n was what happens to the tube size when the VE is increased. It was explained this way:

Higher Compression Ratios = Higher Thermal Efficiencies = Lower EGT's = slower Speed of Sound or slower Wave speeds = shorter Primary Pipe lengths + Collector Lengths = slightly smaller Dia.
Lower Compression Ratios = Lower Thermal Efficiencies = Higher EGT's = faster Speed of Sound or faster Wave speeds = longer Primary Pipe lengths + Collector Lengths = slightly larger Dia.

Just sayin!

Nice results! Congrats! What do you plan to do with the new power? Drag? Flying mile? What valve springs did you use?

Maybe the gains would have been the same maybe not. Might have only gaind 3hp going from 1 3/4 to 1 7/8 or none or less, I don't know. They are two different header manufacturers on a test with no scientific control. I've read that article on the LS3 and would love to see the same test done on an ls1.

Track has been closed almost 10 years now in Kuwait, No Mile Run.

Pac duals 700" and YT Rockers (added to the first post)

Very nice.. my car made 458/430 SAE with the same heads and a 231/237 cam, very comparable setups :)

The 215 TFS flowing 320CFM at intake 600lift and 259CFM exhaust , It looks the torque is falling after 5200RPM .

What fuel are you using?

Power curve is beautiful but your torque curve looks like crap

he did say he had to work on the tune,and it was his first time tuning on the dyno..tough crowd here..
OP,awesome results.post up again after you work on the tune,would love to see how much you improve on it.

nice job man ,,,
best luck and wish

hopefully next step is to use nitrous :D

guys, i have been busy latly, i bought a 2002 C5 Z06 it has headers (stock H-Pipe) small cam, Dart heads and 90/90.

my next step os to swap engines bitween the camaro and c5z and see how much it does on the dyno.

its gonna be a nice apple to apple dyno compartion although the camaro has better exhaust headers/exhaust.
