Thanks again Longass for the Stage 1... It's made driving around town, changing gears and running wide open alot more smoother, torquier, and I'll be damned if my car doesn't sound different... I know it likes to do it's rumbly "backfire" even more now :D:D That always turns heads... ~ Chris |

You're talking about RallyBob's car, which is putting out 275 hp at the wheels (roughly 340 at the crank since he's running a 5 spd). My comment was relative to 300 at the crank (~200ish at the wheels).;) -Bill |

Check my Photo Album (new version of the Lockers) for a pic of the heavy duty, adjustable front sway bar end link. Please ignore the attachment tab on the strut housing (that's what happens when you "go large" on the front bar without adding a full weld bead on the tab:eek:). -Bill |
Where are the new lockers Bill?? Ever since the old ones disapeared I haven't been bothered to try and figure out where the new ones are...

The EG33 powered RS 2.5 finally got dynoed and tuned today. I just got off the phone with the car owner Jack, and the numbers were very nice IMO. I'll try to get him to print out a dyno plot to post here, but for the moment this is what we have. 285 w/hp @ 6200-6500 rpms (flat line) (Dynapack) (up 65 whp) 248 w/torque @ 5500 rpms (up 33 wheel ft lbs) The nice thing is the hp and torque curves below these rpms are virtually unchanged from before. In other words it did not lose 'down low' in order to gain 'up high'. Although peak power occurred between 6200-6500 rpms, there was less than a 10 hp variation from 6000-7600 rpms. It was run up to 8000 rpms during dyno pulls. Previously the power fell off after 5700 rpms (old power peak with stock cams). So a quick recap: *Stock EG33 shortblock with 140,000+ miles on it. *Heads have .5 mm oversized valves, and a bit of bowl porting and blending. *Conversion from hydraulic buckets to solid buckets. *Web cams, stock cores welded/reground. .444" intake lift/.460" exhaust lift/ 244* @ .050" duration, stock lobe separation angle. *Heads milled 1 mm for compression. *Custom cold air box. *Custom headers, 1.75" primaries 31-31" long, into 2.5" collectors, both banks merged into 3" main exhaust, one racing muffler. *Autronic ECU is putting out 356 - 335 Hp at the crank (again with 15-20% loss....390 with 27%):cool: -Bill |
If a 5mt SVX makes 168 whp with a rating of 230, or 73%, then a whp of 212 is equivalent to an engine rating of 290. That 212 whp was at 5700, the engine was still running stock cams.

Yeah, I fell back on my old "15-20% loss for a 5spd" figure instead of 27%:o -Bill p.s. I went back and edited my earlier post |

Thanks Phil! Do you know what paper that was found in? I wish that grill would have made production. Oops, don't want to hijack this great thread with a grill statement, but the article itself seems to give the idea that the test car was not over 300 hp.

8,000rpm!!! On the stock block!!! So stock rods, stock pistons?? I am rather suprised... I think when I build mine I'll definitely be building the bottom end. But it makes me feel better now, hearing that atleast the bottom end can take that kinda abuse :D Quote:

If Chris is at 183 with 5MT, Stebro and programming, and RallyBob at 212 whp with 5MT and major changes from stock, both with stock cams.
Any guess as to how much the header/race exhaust contributes to the power, coils, different intake box, standalone, etc. Where is that power coming from, still at 5700 rpms? Quote:
