Boosted LT5's

[Billy Mild]

For such a great motor, I haven't seen much for boosting options. I have seen the Raptor rear mount turbo kit, but no superchargers as of yet. Is there a reason for that? Too high of compression? Is it because NA mods see such great gains? Is nitrous a safe option?

[KILLSHOTS]

I'm sure that the LT5's extremely high compression ratio is the primary reason that boosting is uncommon. And the rarity of the engine means there's virtually no market for pistons that reduce the compression. Head modifications to reduce compression? Maybe, but with an old aluminum engine, it's potentially a bit more problematic. As far as nitrous is concerned, Marc doesn't recommend it. The market has shown that as far as increasing power is concerned, the LT5 exemplifies the old axiom that there's no substitute for cubic inches. Wish I had the money - and the will - to rip into mine and take it to 415 or so.

[LGAFF]

Open dec also did not permit much boost....turbocharging lead to head gasket failures...Haibeck has a gasket to address I believe.

[cvette98pacecar]

What no Twin Turbo LT5? There are a boat load of them out there.

Twin Turbo LT5
SGC-Three is you count Wayne twice as you should (high and low boost version)
LPE- Four and Norms has 1000 hp.
Callaway - There were three originally but I have seen the hoods that would support 5 cars. Hopefully Chris C or Reeves will chime in.
Raptor - One with the second on being built right now by Henderson Motor sport.
Mallet - One

Single turbo
Mark Haibeck

Supercharger
Specialized Racing products.

Now Mark Horner or Jerry Downey was telling me about a 385 Twin Turbo in Texas, I do not know if that is included in this count.



That makes 16 that I know of.

People said this about the 944 Turbo engine as well. It is open deck. One way around that was either using iron sleeves, or putting cement in the engine block to stabilize the cylinders.

Before the ZR-1 I was big into 944's. Still one of my favorite cars of all time. There were a few guys who made a "hybrid stroker" engine. Granted I don't think the LT5 has rod bearing issues like the 944's do, but the stabilizing of the cylinder is still good food for thought.

I have seen some random ones on the internet, just not a lot. I guess these were low production cars so most would rather keep them in the garage and wipe them with a diaper...

I'm sure these builds are $$$$$. Much more than I can afford. Haha

I think by the time you figure out how to do it and the money spent, you could just get a Mk4 Supra or a twin turbo LS C5 or something.

Some of the FBI gang here in northern IL have gone the AES (http://www.aesracing.net/product_info_lt5.htm) route and converted the motors to closed deck variants - primarily for big-inch LT5 apps., taking a page out of some tricked out, highly forced (Honda) motors.

I'm not aware of any forced AES LT5s, but those so modified stand to support forced induction, according to AES.

[KILLSHOTS]

Yep, that was my point. If 16 or so out of a 7000-plus run have been boosted, that's about .002%, which means that a few guys went against the grain and tried it as an experiment. Sure, it can be and has been done. I could also turn my Camry Hybrid daily driver into a weekend track car...but it's probably not the best platform. Other than "what the hell, I've got WAY too much money in the bank!" type of guys, why would someone start with an old, precious, HIGH-COMPRESSION aluminum V8 for a boost project?

[rkreigh]

packaging for the front mount turbos is very tight!!

I think the AES liners would really help

as would e85!! the LT5 isn't the best choice, but it's certainly doable and the end results as evidence are glorious

Hey Robert,

the 385 TT belongs to Will B. and is included in the 4 LPE builds

let me know if you get your manifolds done

love to see them!

I "heard" that project didn't turn out so well and NRE threw the towel in.
It would be very interesting to find out what he did to the heads etc. One of our major hold backs are the intake.

We could build a turbo LSX engine for less than a third of the price to do the same to our LT5's. And get twice the power and reliability out of the LSX.

I'd love to get my hands on a ZR-1 with a bad engine.

Hey wait just a second. I own a ZR-1.....I think. Or was that a dream ?

I'm planning to build a single rear mount turbo for my Z in two years. Currently gathering data and knowledge before executing. I have so many ideas that are out of the box and you will not notice it up front, it will be hidden. :-D:-D:-D:-D:-D

I would do it sooner but I am currently out of country, which means I have a lot of time to plan and research.

That is a great idea. rear mounted turbo will keep engine bay uncluttered. I have seen twin turbo versions on ls cars and they work quite well. I would not run too much boost and you will have some lag because of the length of the piping from front to rear etc..

Ed/come ride in my t turbo fidanza corvette/w lingenfelter motor/the only lag is until you let up and let the tires get traction/ls3 417cu/

[edram454]

Ed/come ride in my t turbo fidanza corvette/w lingenfelter motor/the only lag is until you let up and let the tires get traction/ls3 417cu/

of course you have a stroker twin turbo setup. You wont even feel the lag. I have a buddy with a twin turbo stock cube ls1 with turbo mounted in the rear of car and he said there was a difference compared to turbos installed in the front of the car opposed to the rear of the car.

Your big cube small block already has torque without the turbos so lag will not be present. I have seen some mustangs run staggered turbos one small one and a large one totally eliminate lag even in small cube engines. I bet your car hauls big time.

ed ramos #3028

[edram454]

I will mention on event that happened when a fellow corvette club member and his 2010 z06 twin turbo car. He is a very experienced track driver and teaches driving classes in sebring and homestead tracks when they run track days, his twin turbo rear mount setup began to leak oil from one of the turbos in the rear. He did not see smoke and there were no signs of any issues when his car caught fire. he didnt lose the car since he was notifed immediately and drove off the track and put the fire out. He had damage but nothing a new bumper and paint did not fix. He was personally disillusioned with that twin turbo set up and sold the car. He then got that money and bought a built ls7 z06 car and makes his power naturally. fyi..

ed ramos #3028

[diamond zr1]

that is exactly why they should be in the rear/anytime you get Hot oil on headers you will have a big fire quick/I also have a 91 Callaway t/turbo car with turbo's bottom front/lots of heat/350 cu in/they have secondary fuel injectors in the ram horn at front of plenum held in by retaining clips/had one come out one day sprayed gas all over underside hood and motor/thankfully I was unloading it out of a trailer and the motor was stone cold/

ed ramos #3028
Hi Ed, some guys are worried about turbo lag but I figured my power doesn't come in till about 3500 right now anyways. I have currently 442/391 at rear wheels and with my engine mods it moved everything up north on the RPM scale.

Lag is based off of size of turbo, distance from engine, heat and velocity, exhaust pipe size. There is a balance between them all that must be found to minimize it. Oh and not to mention turbo inner works such as old school heavy weight turbines/ ball bearings vs. ceramic ball bearings and light weight turbine wheels.

I will retain my stock compression ratio so torque should remain the same until boost kicks in. This is what I suspect as of right now. I'm planning on about 5 lbs of boost. Deciding on adding additional injectors for a stand alone controller, factory ECM will be untouched. So idle and power remains the same until boost is detected by 2 bar MAP sensor. So many thoughts on this.

Some times you have to think out of the box at a distance of 50 feet, and not letting someone tell you it can't be done. :-D

that callaway custom TT car was at the gathering a few years back and got my heart racing what a beautiful car!!

love to see more TT ZR-1 being done

the AES liners are going if for me and hopefully robert will whip up some modified stock manifolds for me for a more affordable setup

the raptor is a good solution too.

with improved studs and liners the LT5 although certainly not ideal, can survive some boost

I think E85 is the magic bullet here. I'm going to try some of this stuff soon on the TT Z06, as soon as I can muster some mod $$

He also has a very low mile all original black on black 1990 ZR-1 in climate controlled storage. The other three are LPE 368 TT's And the owner of one of those cars lives in Conroe TX. Will is a class act and one of the old timers in the C4 ZR-1 game. When he gets back in town me my wife and Will and his wife plan on going out for dinner. And he promises to give me a ride in either the 415 or the TT. I can't wait.:cheers:
