They only need 520s-550rwhp to get to the 9s...

 

That's the thing that puzzles me about Marko's car.... everyone is bragging how he dyno'd 1200rwhp then went out and ran that 8.45 at ~164 (i have the vids also). Now this sounds a little wierd to me... how does Harlan's 'hawk and BigRick's 'bird run 8.20s and 8.30s at around 170mph with only around 950rwhp? Watching Marko's 8.45 videos, i see VERY little lag off the line. If he is in fact making a true 1200rwhp shouldn't he be trapping close to 180mph? I've seen a few members on other boards and this one point out how his dyno looks like one huge converter spike. His car is bad-***, i'm not denying that... but the numbers are funky when you look at the whole picture.

And that's ****ing insane running that much boost and nitrous through an engine!!!! (i'd love to see what a 350-400 cubic inch V8 could do with that combo )

 

Also the supra i drove was MUCH faster than any "similarly modified" Camaro i've ever seen. His supra has a catback exhaust and that's it and he's run low 12's on his drag radials...His is a 6speed and he can drive the crap out of it!

I wouldn't say that low 12's with drag radials and a cat back is MUCH faster than any "similarly modified" Camaro, LS1's especially.

 

I didn't drive one, but i sat on an 847rwhp supra and it did feel stronger than my 607rwhp camaro at that time... but not that much.. it was just that it came on hard and mine came on progresively...

but when i looked at the speedo.... hmm.... i started wondering... also his skills where awful, but... still preferred my 607 at that time... i will get nailed down my combo pretty soon.. I FREAKING HOPE...

 

I'm going sit on my soap box and bitch for a little bit since this week has sucked bad enough already



I'm sure he's upped the boost some. I doubt he went from mid 13's to low 12s with just a cat-back on stock boost. Any kind of factory turbo'd car can be made "fast" easily though. Hell my GN was hanging with two of my friend's high 11 second fox-bodies (one 11.86 and the other a 11.98) and one 383 monte carlo running similar times up to 120mph.... and all i did to it was upgrade the turbo to a TA-49, went to 36# injectors (with matching chip), and cranking the boost up to ~26psi (up from ~15psi stock). This was with pump gas and alcohol injection. Dropping about 2 seconds off a 1/4 mile time with only a few hundred $$$ in mods is easy in a turbo car. (FWIW i spent a little over $800 to get there). The trick is to concentrate on mods that allow you to run more boost.

Supras are good cars. But it makes me laugh when everyone always gives the big "Ooooohhhh!!" and "Ahhhhh!!!" when they see one making 8-900rwhp. Well look at what's going on... with 30psi+ of boost and nitrous (or all turbo at 40+psi) i'd hope they make that kind of power. Most turbo V8s i see barely run more than 15-20psi and make 800rwhp+. I've pretty much decided that when i got out of school, i'm taking my LT1 and applying a little turbo buick and supra ideology of modding to it... build a strong forged bottom end (355) with a SBC main girdle, block fill, getting a turbo(s) on it to handle a LOT of boost, O-ringing the ported AFR or TFS heads with good gaskets and studs, (a few other things).... and cranking that turbo up to blow as hard as it can ****ing blow (and limiting the rpms to around 7 grand for durability). Jose reported one of his customers with a 355 LT1 made around 980rwhp with 23psi from a ~76 GTS turbo. i'd love to see what would happen with 30+ and a larger turbo.

 

sleeperz28 did 1000rwhp already

 

I dont see any similarly modified SS's or T/As running low 12s at our local track where the supra went low 12's (4000feet DA's). Fastest "all stock" LS1 was 13.46...He did up the boost i believe but it was made on PUMP GAS so not enough boost to cause detonation and require higher octane. I plan on adding a little boost to the LT1 in my 69 when i'm out of school but i'm just saying dont discount supras because alot are dynoqueens, there are quite a few that are turning respectable times with the power they have and make an even better highway racer.

William

 

So let's up the boost on the LS1 to match and see what happens. . .

 

Boosted LS1=awesome...but not as easy as "upping the boost" on supra.

There is a local guy that has a boosted LS1 but he's yet to have it make a decent pass and get it running the way it should. Hopefully he'll get it going the way he wants...It was a nitrous LS1 that was running 10.6.

William

 

BigRick has broken 1250rwhp on his 398 LT1 with 23* heads. But I'm not sure how much boost he was running... i know he was switching between a 91.5mm turbo and a 100mm+ turbo when all hell broke loose between the trans and the turbo (the LT1 block itself lived). Probably the best example of someone who decided to go ALL-OUT with a V8 on boost with the 4th gens. I know of a few turbo'd 3rd gen f-bodies that are purely SICK (sub-5 second 1/8th times).

I just hate to see when all these L98/LT1/LS1/mustang/etc people are all the time wanting to sell their car and "wishing to have a supra" just b/c they dyno so high. This infectious "fast and the furious" crap is getting old. How about pushing some serious boost through a big-cube V8 rather than some little 3.0L? That's my point. It's basic engineering fundamentals, larger displacement = more potential and take advantage of the extra cubes. If stock-block-splitting is your fear, buy a DART or WP SBC block... those have been PROVEN to over 2000hp. I'll keep my ****ty LT1 camaro thank you. Rather than suck supra dick why don't more people get down to the basics and get to boosting their V8s?

>>(I realize that at some point in power a street car is doomed to be a track-only car and not everyone is aimed at making that much power. I'm just damn tired of all the talk about abandoning american V8s for these turbo'd 6 cylinders for the best streetable power. Displacement matters, and you can't get around the american small blocks for being a perfect compromise, especially when talking turbocharged setups. While i do give props to the Supras and Skylines for their mega-achievements, i'll never abandon the potential in a turbocharged V8.)<<

 

SW's supra had a 90 shot of nitrous and was running 2 bar, not 30+ psi.
I oooooohhhhh and ahhhh over the supras making these numbers on STOCK MOTORS!

And of course a larger motor is going to make more power boost to boost. you have to remember that supras are barely half the size of our motors.

lastly, good luck with your build up, i wish i had money to do a turbo setup on my car. who knows maybe Performance Motorsports will make a turbo kit for fbody.

 

Or an LT1 or L98 or even a mustang V8.... i'm glad to see we think alike . Turbo'd American power!!!

 

I agree to a point, and 2 bar is still what... 28 psi? Then a 90 shot on top of that? What would a stock top ended LT1 or LS1 do with that on a forged bottom end? Stock engine or not, i'm sure you can still invest in an awsome bottom AND top end in a SBC with a turbo kit for the cost of what it takes to get a supra to those power levels. And you'll have a much more broad powerband.

 

2 bar= 29 psi, which is about 30.
