The dip in power @6400rpm is from the IAT sensor pulling timing. Judging by how power was climbing it may of made 880 had it not. I believe it also pulled timing@4900rpm.

The air fuel is on the rich side and IMO is conservative. There is more power in leaning it out. The wide band sensor in the tail pipe the dyno uses is .5-.7 leaner on average than what is in the collector. We confirm this by reading plugs and we have 4 other portable wide band sensors that all confirm it's leaner.

The plan though is to leave it as such and go to the smallest 8-rib pulley A&A makes which is a 2.85". We're hoping this gives us 20-21psi. Judging by the power it made on 17psi, 21psi should deliver some very interesting results.

Almost 900whp on pump gas. Impressive!!

I see its on the tick tr-6060 also, awesome. Gotta love a huge power manual transmission car.

Are the accessories upgraded to 6 rib? Also how does the owner like that clutch?

Accessories are not upgraded to 6 rib. The owner has not driven the car yet, but it feels nice IMO.

Sick numbers I bet it will be over 1000rwhp on 21psi with little more aggressive tune.
Great work Martin and Tick crew I'm surprised you didn't go with higher compression??

Congrats to the owner love the setup small CI and big blower looks like if it didnt pull timing after 6400rpm it will be 900ish

It would be nice to see NA dyne numbers. Not many TFS 255 builds /dynos # out there.

We wanted a very safe set-up for this customer. He uses this car to roll race and compete in standing mile events.

We needed a set-up that he could stay in the throttle for extended periods of time and not have to worry about the tune-up being "on the edge". Especially when using pump gas. The owner was adamant about his tune not relying on a ton of methanol or race gas to keep the tune up "safe". Thus the lower compression.

I would also have to agree that it would of come close to 900, but I like to "guess conservatively" when I'm bench racing.

What I like about this set-up for being a centrifugal combination and small on displacement is the torque. 500rwtq by 3400rpm. I feel the small runner heads and smaller cam are helping the early torque numbers.

The flow sheet that came with these heads showed 380cfm@.700 and 245cfm@.700.
I have a customer with these heads, LS3 Polluter cam, Fast 102, 10.8:1 compression and the normal bolt ons that made 510/470 and has been 10.70's@126 in a full weight 3600lb. F-body. It's a 6 speed car and he lives in Florida so the air isn't the best. I believe the DA was 2000+ the day he ran that pass and was only shifting at 6500rpm.
Yes!
Mark,

I do not receive PM's. Email or calling the shop is the fastest way to reach me!

Well guys we did it. We fabricated the new intercooler, tossed the smaller pulley on and these were the results. We know it has a 1000rwhp in it, but for now we're not going to push it and let the customer enjoy it.

It's been in our shop for a long time, and he deserves to finally enjoy all the money he has put into this pump gas beast.
