Looks like Hinson has seen the light and is finally going back to a twins setup...






lol...all I can say is

 

thats sick, i love it.

 

Yep, amazing.

 

what's that?

 

What kinda hp is a setup like that going to yield?....Wow...sweet looking.

 

He says they are shooting for 1000+

 

Insane........

 

Seen the light? He might have a set of turbos and some fancy heads but he riped out its heart and soul.

 

oh SHUT the F UP!

heart and soul of a decrepid man with blockage and potential for immediate and unwarned DEATH. Replaced it with something that makes WAAAAAAAY more sense for someone that wants to drive the car day after day....

 

Riiiight.

 

So, so dramatic.

Get a grip! Its a car.

What are they planning on doing with the head lifting? Looks absolutley SICK!!!!

 

so wait...

if i'm looking at this right, they have a twin turbo ls1 that is using an air-to-water intercooler which is mounted inside the passenger side of the dashboard?

thats some crazy ****!
hope they never blow one of those hose clamps haha, somebody'd wet their pants hehe

 

^^ I am sure it will be some type of AN fitting or something else close to what the stock heater core connections are. But yeah that would be a wet floor for sure!

Also the efficiency of a water to air cooler is only as long as the water stays cooler than ambient temps. So you would have to keep refilling it with cold/ice water to be very eeficient. However for drag racing, which is what i will guess the guys at Hinson did this for,.. it will be fine for cooling. As you refill every time anyways.

I'd be intrested in a air to air IC set-up. But getting cramped for space in there now.

 

i know on the high horse power supras they weld these rings on the ends of the intercooler pipe and use a metal clamp to hold the pipes together.

 

I use those same rings on my intercooler piping.

 

Thats sum goood stuff

 

Holy crap! Hinson mentioned something about prep'in a car for some hot rod magazine.. I guess this would be it! Hope he brings this car to Deals Gap event. Looks absolutely sick! Ive seen his single turbo 62-1 run on the strip and it runs mid 10s all day long... and get 28MPG..

 

am I the first guy to notice the Intake Manifold is mounted BACKWARDS?!?!?! oooooh ****. I never even thought about that... I bet its easy since the heads are designed the way they are.. interchangeable side to side right?

so, the throttlebody is sitting inside the firewall? ...wtf is going on people, this is some cool stuff...

lovely thread title by the way, had me lol here at work... nice one.

 

Nope, you're not the first one to notice.

He doesn't mention that it's backwards, but correctly assumes that they're running an air-to-water IC, so I'm guessing he's aware that the intake is backwards to accomodate it.

As for Hinson taking it to deals gap, IIRC it has a powerglide in it. Two speed tranny + lots of curves doesn't sound like fun to me. It's definitely built to go in a straight line...in a hurry!

 

I noticed the hole cut in the fire wall at the shop , but didnt want to spill the beans . Thought i would leave that up to hinson or lane

 

Matt Harlan doesn't seem to have problems with lifting his heads, and he's around 1400rwhp (8.2s ET in a 3500# car). IIRC he has truck heads, ARP studs, and is using 6.0L MLS gaskets. IMHO the studs are a must if you're planning on running any serious amount of boost through an LSx motor.

I'm guessing that people who have issues with lift also have issues with their tune. Harlan ran shitloads of boost/power with minimal issues, so it's possible. He sold his twins, and has something new planned, so I guess we'll have to wait and see.

You can always upgrade to AFR heads, which have a thicker deck than the GMs, so more clamping ability. Some people seem to like the thicker Cometic gaskets too, which can lower the CR a few tenths.

 

Are you guys "positive" that Harlan doesnt have any other modifications to keep the heads down? Originally, when i was looking at engine choices, i visited ls1tech.com. Maybe im crazy, but, i thought that all the guys were having the head lifting problem as soon as they started making 800+rwhp, no? Im no expert,but i thought the reason was that some sort of(pins, i think) were not being able to be held by the aluminum block( Bare with me as im just going off of a smokers memory ) I thought that was a big reason that the guys who wanted to make 1000+rwhp used iron blocks like the Lt1.

Cant wait to see what harlan has next, should be insane. That team is bad ***!

Hey, who the f*ck wants a chevy anyways, hahaha

 

Pretty sure. Check out this thread,

I don't think he changed his setup too much from this point before he ran the 8.2s ET. Mostly dialing in the suspension and upping the boost a bit.

Pretty impressive when you consider its on the stock crank too.


Maybe?

Lots of people do. People get around it with studs, gaskets, thicker decks on the heads (AFRs), or O-ringing the heads. Even the C5R guys suffer from the same problems, and they seem to keep their heads down at 800+rwhp. it's kind of like the fuel system. If you plan ahead, it's not an issue. Overlook it, and you'll have big problems.

The LS1s design has each cylinder clamped down with 4 bolts, the LT1 has 5. that extra bolt helps with clamping force a lot. Early run LS1 blocks had issues shitting sleeves at high power levels, and there were some concerns with block flex because of the aluminum. Neither of those appear to be a big concern anymore, as there are a lot of people running around with 700+rwhp on stock blocks (forged bottom ends though).

Yup

Especially when you consider that it's literally four or five guys working out of their home garages wth no sponsors.

How about those of us who've owned 302s and decided to grow up a bit?

 

Yea, harlan is doing incredible things with the resources available( I see a harlan/Marko(SP) race being the "ultimate street/drag car race")

Maybe i was thinking of pre99 blocks. They were the ones having the problems, right?

Yea, harlan and those guys are awsome for doing ALL that on a stock crank.
