So that brings me back to my actual question: can a LT1 Fbody be Nationally Competitive in ESP?

Let’s face it even with every ESP legal motor mod a LT1 is only going to do maybe 275RWHP. LS1 cars are doing 290-320 RWHP STOCK and with the full array of ESP legal motor mods can put down probably 350RWHP. I’ve heard of a few ESP cars that claim 400RWHP ESP legal, but frankly I don’t buy that (I’ve been around the LS1 community a long time and outside of this particular car/driver’s claim I’ve never seen a bolt-on LS1 make those kind of numbers).

On top of that a LT1 car is probably an extra 100lbs nose-heavy.

So, what do you all think: Can a LT1 still be Nationally Competitive in ESP, obviously excluding the driver issue? (IMG:http://www.frrax.com/rrforum/style_emoticons/default/wink.gif)

Is the car already too modded for F-Stock? If not, FS is way cheaper to run than ESP, and a very competitive class. And since all FS f-bods are forced to stick with the stock 16x8 rims, the extra 50hp isn't helping the LS1's that much. LT1 cars are competive in f-stock. Hell, 3rd gens are still winning National Tours, so it's anybodies game. And after checking the results from this weekend's prosolo in DC where an LT1 car finished 2nd in ESP, I'd say they're competitive in ESP too.

Yes LT1's are very competitive. The LS1 cars make more peak Hp, but it's from about 5300-6000 rpm. There are not many courses that you get to rev that high in 2nd and even when you do it's for a very short time. So all the extra hp means nothing if you don't spend a lot of time in that rev range. As far as SCCA classing the LT1 in ESP can use the 93 trans which has deeper gearing then all the other years. So the LT1 actually has an advantage that the LS1 cars can't get because the 93 trans won't bolt up behind an LS1 in ESP legal ways.

SCCA got those results up fast. Actually I hadn't even left the site yet at the time of Jeff's post. I just got home from the DC Pro and my car is still on the trailer with all the stuff in the truck. I'm hoping I get motivated to take the car off the trailer tonight, but the AC in the house is so nice after all the heat and sun we got today.
