glad to see its all coming together now. i have been wanting to see what power that thing was going to make ever since i signed up on here...

 

I was just talking to Mike @ Yank, and he said he thinks the T400 loss is 16%, but I think he's wrong.

 

Congrats! Incredible numbers! Glad to see your quest is nearly at an end.

 

simply awesome awesome awesome. cant wait to see the dyno graph. where did this combo peak?

also john, for years we have been talking about mn6 cars loosing 12-15% and autos (4L60e) loosing 18-20% but ofcourse it gets skewed at your power level. i believe teh th-400 would loose as much power if not more as the 4l60e - but this is speculative.

 

Congrats again John, glad to see everything is working out now..........

I can't wait to see that monster run at the track...........

I would say that the loss with a TH400 is no less than 20%

 

awesome John. I am glad to see it coming to gether for you. Now I really cant wait to race in the spring. I just want to get my tranny fixed and run the car...lol 9.50's here you come

 

Scott, I think an intercooler swap will make a very big difference, based on that conversation we had a while back, I am running 5 more degrees of timing with the same gas. I really held back on bigtime pimping the Griffin stuff until I saw the numbers were going up and we were still running 23 degrees of timing.

 

I see one of those bad boys in my future.....

 

if the convertor is efficiant, we have seen cars make more power with the T400 and a good convertor , over the 4l60e with a convertor.

 

Great numbers guy! So what cc dish are your pistons? How much compression drop do the 6.0L heads give you, say on a stock compression block? What is the cc of LS1 heads? What is the cc of LS6 heads?

Congrats!

 

Diamond pistons:
3.905 3.622 6.125 1.315 4314 .927x2.950 -8.6cc

6.0 heads have 70cc chambers stock, LS1 heads have 67cc chambers, I did the 6.0's mostly for the stage II porting and valvework more so than the compression drop since my 6.0's were cut to 69cci so the difference is only 2cc.

LS6 heads are 64cc's I believe. 6.0 heads are lower compression LS6 heads basically, and I did mine because they flow over 330/220 which I wanted. (Not the best 6.0 head flow numbers out there either these numbers are fairly average)

 

Hey, thanks for the info!

 

Way to go John............... Hopefully us ATI guys can hit numbers like that when we get this Cog pulley stuff straightened out......
I would be very happy with numbers like that with my new setup.
Kyle

 

Yea, I would be happy as well.......

 

I'm sure you guys will figure out the cog setups. Who knows I might do one too someday.

Intmd8, can you email me the datalog so I can send it to Craig at FAST?

 

Wow!!! Congrats John!!!!!!!!! That monster is coming along..

 

Awesome results John; now you just need to send in the YS for the YSi upgrade and put down 800rwhp. I'm curious what the flow rating of the intercooler is?

 

The YS is rated at 1500 cfm and the Griffin intercooler was designed by Jim Burns over there to support that.

I would be curious to see what the YSi + C16 could do actually.

 

Very nice. Congrats.


Bruce

 

Man, that's awesome!

If I can venture a question... is RWHP on the dyno derived from the RWTQ value? I thought a dyno effectively measured torque, and HP was a computed value.

Anyway, great numbers... there's probably more in it.
