Bolt on LT1 vs. Modded Hyundai Genesis

I've seen dozens of LT1's dyno on various dyno's. Along with an equal amount of LS1's. I've seen a bolton LT4 headed, GM hot cam LT1 Fbody that only made 294rwhp. The rest of the bolton LT1s were in the 260-275rwhp zone. Hell, I also saw a loping cam'd LT1 vette with LT headers and a aftermarket aluminum intake only hit over the 300 mark AFTER 3 tuning pulls that were under 300rwhp. All this on two different dyno's. It's akin to saying a bolton LS1 is making 375rwhp: 25rwhp more than there engines made at the crank from the factory.

I was like really...really tired and thought about going into 2nd but thought I would have been at the limiter almost instantly after I took off...my car has 3.73's (I think), usually shift at ~5500, stock limiter (untuned).
Sticks n Stones, you have seen some really ***** cars then.
Here's a video that may clarify a bit.

Thats an automatic 1993 LT1 - the first year they came out, being the lowest rated from the factory, I do believe.
Just in case you don't watch it, which I don't think you will here are the cliff notes:
(stock trim)
-Automatic
-stock gears (2.73 ratio)
-paper air filter
Dyno'd 230rwhp.
Same dyno with mods installed:
(after modifications)
-Flowmaster Cat-Back Exhaust
-SLP 1-3/4" Headers
-Hollowed (gutted) Cat
-Custom Chip by TBIChips.com
-K&N FIPK Cold-Air Kit
-Marches Underdrive Crank Pulley
-Throttle Body Air-Foil
-3.42 ratio rear gears
Dyno'd 277rwhp.
Remember, that was a 1993 auto car, mine is a 1995 M6, it should dyno quite a few more ponies bone stock, let alone with better mods (other than tune and UD pulley).

Yeah like I said, it took FOREVER lol.

Tell me this car couldn't have gotten damn close to 300 rwhp with a tune. Thats a 94 at over 170,000 miles. Mods were K&N CAI, air foil, Pacesetter LT and ORY, Mufflex 4 inch, 4.10's, and an aluminum LS1 driveshaft. Thats it.

I owned several LT1's for the better part of the last 15 years and 93-97's all dyno the same...The power rating went up in 96-97 because of the dual cat setup which powerwise did nothing...Hiting 300 rwhp in a bolt on LT1 isnt impossible but its also not as common as you may think.
I mean "common" as in people who actually try to hit it with the right bolt ons, not your general person who slaps a Flowmaster on and CAI and expects 300rwhp.

Don't talk about STD or Uncorrected numbers please.

I love when people post proof to back the claim they're trying to argue.
That dyno is STD corrected and the car made 282whp with more mods than the OP's car. Take another 10whp off for SAE corrected numbers and we don't even have to mention the more mods part.
Try again!

Ive owned and seen dyno quite a few LT1 cars and sorry, not trying to put them down, but they just dont put out great numbers. They are a tad lighter than LS1 cars so they dont have to make as big a number but 300 rwhp bolt on LT1s are far and few between if they exist at all.

I don't know where he had more mods though, if you're just going off my sig those are the "big" ones I've done.
I've got a bunch of little things that should give me a few more, plus a lot less miles should be worth something, my car is pretty damn clean in and out.
I feel confident with a decent tune I could make 290rwhp with my mods, must be the season to berate the LT1's...guess a bunch of kids bought LS1's for summer with their parent's money. (Not calling anyone directly out, just noticing a trend)

STD to SAE conversion is completely dependent on location and DA of the area the dyno was ran.
If you read the temp and correction factor, it just so happens his location - at 65* and 12% humidity, was juuuust about the SAE standard of 77* and 0% humidty. The 65* instead of 77* is worth power, but the 12% humidity compared to 0% costed him some. This leaves the correction factor at a whopping .99.
SAE, in this case, would be a whole 3rwhp lower.
"A" for effort, "C" for execution. Bonus points for spotting the CF used

Dyno tune and 1.6rrs would have gotten you very close to the "magic" 300 mark. A few less miles then 170,000 would not have hurt either.

You seriously believe that the maybe 25rwhp gains you got from those mods put you at 302rwhp? LS1 territory? Might want to take your car to another dyno during a get together with local guys and see what it runs there. Whats your car+driver weight and what mph does your LT1 vette trap and in what DA? Thats a better judge of horsepower.
