Oh Jesus! That's just...WRONG!!! LMFAO :lol: :lol: :lol: :lol:

Man you guys went from talking about the bottom end of a callaway engine to the bottom......Oh nevermind. Anyway, I know the Callaways started with 380hp but didn't the last turbo versions have around 450 in 91. If this is true, what did they do different?

 

87 had 345hp and yes, the late 91's (Speedsters) could be had w/ 450hp - Torque was between 500lbs - almost 600lbs by the end :eek:

What was different - 87 345 horse cars had the IHI (smaller) turbos and in 88 they went to the Rotomaster T04b's 382hp - 90 had 390hp and 91 started w/ 403. Small improvements were along the way each year however, Callaway clearly states the 88+ motors all generally produce the same power - except the late cars w/ bumps in compression - there were also upgrades - a 91 for example, has a 475 horse upgrade which exchanged some parts for the boost (fun pun) in power

Hope this helps :cheers:

Thanks. Exactly what I was looking for.

 

Uhhh...dude...you need to check your facts a little more closely.

Here is the article link on Callaway's own web site http://www.callawaycars.com/Corvette...er_article.htm

It says, and I quote:
"Two people outside the organization had impressed Reeves during the year. One was Lingenfelter, an NHRA drag racing champion Reeves had met during the Gathering of Eagles. "When John's engine broke during a run, he went back to his shop that night and next morning he was ready to go again," says Reeves." I like that kind of dedication." John was selected not only to share the driving chores with Reeves but to build the engine to Callaway's exacting specifications as well. Lingenfelter Racing is located in Fort Wayne, Indiana, and is known for excellence in this realm."

Sure sounds to me like Lingenfelter built the motor....

 

I rechecked my facts - a statement made by Reeves to myself and about 30 others about this - I stand by my original post.

I also checked the list of those in attendance, you were not there.

Firsthand knowledge is better than what one wrote in a magazine - (Check the magazines all published during that period, including the one you quoted and you will find discrepancies between them)

Hope this helps :cheers:

 

some of the callaway guys hang out in the ZR-1 section. Post there asking for 89X2 (chris) or surfinsun. Both know their callaways.

 

Like 89x2 I was there and heard from Reeve's mouth what happened and it's just like 89x2 said. Yes the car did break and yes John did help him get it back together for the record setting run. He did do the driving but not because Reeve was scared.

Lastly dude if 89x2 says something about Callaway's take it as gospel he's by far the most knowledgeable Callaway person on this or most any other Forum. Calling him a Liar (basicly) shows that you are much more ignorant then the false facts you are trying to spread.

Josh and Chris keep sharing the truth and don't let some fool downplay the ability of Callaway engineered cars! ;)

hmmmm stupid question

Does any one know how fast this car would do the 1/4 mile with a set of drag slips? or even normal street tires?

 

I think you are right. I know LPE drove the car and I think he built the motor

 

Yes John " FIXED" the engine but he did not "BUILD" the engine it maintained the specs and design from the Callaway shop but when it broke they didn't have time to take it back to CT. for Reeves to fix it at his shop. John's shop was only a couple hours away and he had all the necessary equipment to fix it. Reeves met John a short time earlier when they did a Tuner shootout together.

Also Reeves was never suppossed to drive the car, but yes his "driver" did back down after the car was soooo squirly on the track. John being ever fearless said he would do it and made history.

If LPE built the motor don't you think John would have insisted that be known? Don't you think the owner of one of the best known Vette Tuner shops in the land would want to be associated with the engine that held the record? The answer to that is obvious!

Last time the engine is a CALLAWAY not an LPE and Reeves did not back down.

 

Ok so it did, but it didn't do it with the 880 hp spec quoted. Had to be more.

 

:nonod: :nonod: :nonod: Some people never cease to amaze me. Can't admit when youre wrong??? :rolleyes:

 

Whats your reasoning? :rolleyes: LPE's original 650hp TT C5 went what 234mph with "only" 650HP.

 

this stuff cracks me up. B/c LPE has a good reputation on the web, everyone jumps on their side. Let me phrase this carefully....

There will possibly be information coming soon about a certain vendor, and what a horrible job that has been done on a customers car, it will shock you. I can't say who's car it was on the forum, but have talked with him and listened carefully, if he wants it public he'll say it. Lets just say the tuner hasn't stepped up to the plate to fix it yet, if he doesn't I suspect then maybe you'll change your opinion.

But for what its worth, get over it. Callaway built the car....the whole car. JL drove it....and it only had 880hp.

 

Boy, did THIS discussion thread veer off topic quick. Remeber the original question?

How did Sledghammer get mixed up into this - it wasn't even MENTIONED originally? :lol:

OK shaggy56, let's see if we can't answer some of your questions. This is just the stuff that I can recall off the top of my head - if you need further info, send me an e-mail or an IM and I'll see what I can dig-up.

The first Callaway twin-turbo Corvettes, back in 1987, actually used a different block than the stock L98 engine. It was a 4-bolt main block that GM was installing into some of their pickup trucks. I don't know the casting number off-hand, but the reason they where used was because Callaway felt they where stronger than the stock L98 block (I don't know why). That changed in '88 when they started using the stock L98 block that already came installed in the cars.

Callaway didn't build the engines completely themselves. Instead, they pulled them out of the cars and sent the complete engine assemblies to Ed Lanier Racing Engines (they built NASCAR engines). The engines where blueprinted to Callaway's specs - all engines had cross-drilled and nitrid-coated forged steel crankshafts installed (I don't know the manufacturer) with splayed four-bolt main bearing caps. Early cars ('87-'89) had Cosworth pistons, while later cars ('90-'91) had Mahle pistons; you are correct, the compression ratio on all the cars was 7.5:1, but only until '90. In '91, Callaway offered a special optional 450bhp 'California-only' engine with 8.5:1 compression. Up until '91, the cars used the stock cam shaft; the cam was revised for the special 'California-only' engine in '91. the heads where also stock castings, but I don't know if they where ported and polished, or if the valves and valve springs where replaced with better units. The same goes for the TPI intake - I know they used the stock runners, but I don't know if the plenum or intake manifold was ported and polished.

Once the assembled engines where returned to Callaway's shop, Callaway installed a few special in-house designed/manufactured items. For example, the starter motor relocation bracket - the starter motor had to be relocated to clear the turbos. They also installed the exhaust manifolds, and the turbos. The turbos on the early cars where compact RotoMaster turbos - they changed to Garrat turbos in '90 (I think). Callaway also used their own designed/built aluminum radiators.

Early versions of the engine used what Callaway called their Microfueller II computer. It controlled 2 additional fuel injectors that where installed in the airhorn just in front of the throttle body. By about '90, Callaway had begun to work closely with GM engineers and began to modify the base coding of the factory ECM, eliminating the need for the Microfueller computer.

The introduction of the Paul Deutchman designed AeroBody package in '89, while not an engine improvement, did improve the airflow to the intercoolers by some 60%. This helped to increased the horsepower without any other changes to the engine.

The Seldghammer was a special - one-off Corvette that Callaway built to answer a challenge to build the world's fastest street-legal car. True, it holds the record at TRC, but Callaway also built a Corvette called Top Gun - another VERY fast Corvette that everyone seems to just forget about. But either way, these cars - as great as they are - aren't very representative of what Callaway was doing for the production cars.

I could keep writing, but I've already written a small testiment here. If you need any more information, e-mail or IM me.

I hope this has helped.

I believe you might be mistaken about the microfueler on the Twin Turbos. The micro fueler was used on all TT's to control the supplemental injector in the rams horn just before the throttle body. There have been a couple of cars that had been modified and used an aftermarket fuel management system.But otherwise all TT's have a MicroFueler :auto:
