jack46 Posted June 1, 2009 Share Posted June 1, 2009 Are you sure you have a big enough turbo? What size is that monster? I am using two 60-1 on an LT1 build. They will peek out the hood the headers just got ceramic coated today so hoping to get progres in a couple weeks. What hp are you shooting for?

Tempered Posted June 2, 2009 Share Posted June 2, 2009 holy turbo. I couldn't help but picture the car causing a rift by going into warp speed when that baby kicks in! Sonic boom maybe? Very nice ! Quote Link to comment Share on other sites More sharing options...
Arif Posted June 2, 2009 Share Posted June 2, 2009 Wait for it. Wait for it...booom! Off to warp speed! Quote Link to comment Share on other sites More sharing options...

They will peek out the hood the headers just got ceramic coated today so hoping to get progres in a couple weeks. What hp are you shooting for? 75mm borg-warner S400. has a really wide compressor map due to the extended tip compressor wheel technology. The turbine is split scroll 1.32 a/r T6 flows a ton I really dont know what HP to expect and when it will spool with the 6 speed..? might not even spool first couple gears! a member on here dustin280zx made 500Whp @5 psi boost.. similar setup but he has big ported heads and big cam. Im going to see what i can do with stock unported heads Quote Link to comment Share on other sites More sharing options...

The love of JDM Posted June 2, 2009 Share Posted June 2, 2009 What are you going to do about the top of the turbo there? Looks real nice through out the car.. Quote Link to comment Share on other sites More sharing options...
a6t8vw Posted June 2, 2009 Author Share Posted June 2, 2009 What are you going to do about the top of the turbo there? Looks real nice through out the car.. A friend of mine has a english wheel and hammer. I think ill have a wack at making a bubble to cover it and weld it on... OR a cowell the hood but might not look that great?

The love of JDM Posted June 2, 2009 Share Posted June 2, 2009 Id do a hump rather than do a raised hood, just my take on that. For the hump, Id have one made where its basically the length of the hood so its not so noticable Quote Link to comment Share on other sites More sharing options...

Im going to see what i can do with stock unported heads I did a rearmount Buick Roadmaster with an LT1 used a stock cam (191/196 .421/.431) with stock iron heads and it does well. It has a T70 with .84 hot and on street tires it did 13.1 @112 with a 2.1 60. I had to feather a long way, given the car is 4400lbs that is ~400 RWHP so small cams and stock heads are quite capable. I will be running it again with ceramic coated manifolds and expect to do alot better with slicks. Stick will hurt the spool but when it hits it will be one hell of a kick in the seat. Look forward to seeing more. My Z will have twin 60-1 (knock offs for now) and I expect to run ~6 in the 1/8th but likely will need juice to get it to spool.

Im going to see what i can do with stock unported heads My turbo was a s472 with a 1.22 a/r. I recently put smaller heads on (canfield 195 cc's) and a s475 with 1.10 a/r. I spooled it up to 8 pounds on the foot/ebrake no problem just under 3000 with the s475. You should have full boost by 3500. And my cam isn't that big. Just has .601 lift with 1.6 rockers. the duration is mild. the most mph I got in the 1/4 was 141 with the smaller (s472) turbo and brodix heads. With the weight of the car (3260 give or take 10 pounds) it comes out to around 628 rwhp. Hopefully with the smaller heads and s475 with the 1.10 a/r and bigger turbine wheels it will be alittle more. I've found out from talking to a couple guys that heads don't matter TOO much with forced induction engines. It seems just as fast as before, but the track will tell once I get it to my standards. The reason I say more hp with the new combo is because my air fuel won't be in the 10's before boost. Nice headers Quote Link to comment Share on other sites More sharing options...

You think this 1.32 a/r will come in by 3500rpm?, man that would be sweet! How do you like your WG setup? i was thinking of doing the same.

cygnusx1 Posted June 5, 2009 Share Posted June 5, 2009 That's going to look great at night when the turbine is cherry red hot and sticking out of the hood! Quote Link to comment Share on other sites More sharing options...
Rustyfriend Posted June 6, 2009 Share Posted June 6, 2009 I wonder instead of trying to fab up another full piece of sheet metal, if you could take another hood, cut the "hump" out, and put it on top of the existing "hump" to further raise it and make the "hump" appear to grow Quote Link to comment Share on other sites More sharing options...

How do you like your WG setup? i was thinking of doing the same. It should come in around there but it depends on your cam, a/f, timing, ect. Put the waste gate as close to the merge as you can. Mine should have been closer as I get alittle creep at low boost. It holds anything over 10 pounds excellent though so I'm not changing because I'm not going lower than 15.
