Well, I decided to head down to the Dyno today. I knew the car was making more power, but I just didn't know how much. My last dyno I put down 372.6rwhp & 344.1rwtq. Since that time I went up to tampa to have a custom tune done and left with 381rwhp in 80%+ humidity and 90*+ temps. I got my SLP Power-flow exhaust installed. My CS tube came in so I added that to the existing MPD airbox setup. My most recent mod was the ASP pulley which we installed 2 days ago. The car is very fast. The last time I went to the track before any of the afformentioned mods I was able ot pull 13.2-13.3 all night with 108-110mph traps. I knew when I went out last weekend and raced a lightly modded cobra and was able to put up a decent fight and my car was running much better. Ok, I posted a chart of the last run I did before the last round of mods.


As you can see there was a nice jump in the torque curve. The car overall is a complete blast to drive. Below is a dyno chart of the car when it was stock VS. the latest round of mods as well. The only thing left to do as far as power adders is a FAST 90mm intake/TB and my Steelworks longtube headers(which are in transit as we speak). I don't know what kind of gains I'll see with the headers but I assume a little more tq. I'm hoping for 15-20 more but based on some of these JBA gains people are posting I don't know if that is going to happen. I considered getting rid of the cats, but I'll keep them and see how much power I can make with them. Any guessers please post away!!

Very nice! It's nice to see a strong, stock block, N/A GTO out there.

Thanks guys any ideas on how much HP I'll p/u with the LT's?

I would say 5-10rwhp more.

Not bad for shorties. When I was cam only, I gained 15rwhp going to long tube headers from JBA shorties. Im sure you will see at least 15rwhp from the headers alone being added.

52172

yea not bad for shorties I make around 425 with JBA's I was very impressed with my numbers.

Long tubes will make a big difference on a reverse split cam. I'll bet that LT & ORP is 20HP or more on your set-up. You may need to touch up your tuning to get full benefit.

Nice graph.
Why dont you cross your torque and HP at 5250 like every one else?
Every dyno you look at on this site has the HP and torque meeting at 5250 but yours is way off.???

Look at the sides. The HP and TQ aren't scaled the same.. They only cross at 5252rpm on the same scale.

Nice numbers I'd say with the FAST/90/LTs and some tuning you could be looking at 440rwhp. That would be incredible.

That is right where I want to be as well. Then it will be a 402 or 427 cu motor for me. Goal is 500/500whp/wtq. I'll have to look into the best pricing on the FAST stuff.

Is this the slp package with the 234/228 113lsa cam and heads that have the part number ground off?

My Dad had this package on his ls1 camaro for a while and it dyno'd 440 rwhp and 405 rwtq with the stock ls6 manifold.

I'm just letting you know that if this is the same package, there is A LOT left on the table somewhere in your setup.
