This is awesome if not somewhat unbelievable given the budget. I have no clue how a lsx swap can be cheap. I am curious what record you are going for. Fastest under 5000? Surely this 3000 pound tank cant compete with THE COLT |

it should be faster than the colt. Budget-I got lucky with finding an incomplete project car with all the right parts, just in a lot of boxes LOL. Retail of all this junk would be 10-12k, but really its no different in the DSM world. Always buy used! Goals? 840 whp (current stock LS! record is 839whp) When/If I do that-shoot for 1000+whp on a 6.0 or 6.2 truck motor. In between that- 9's@anything on street tires 200+ in the standing mile.

I'm about to pick up a 5.3 with everything on it for $500. Could get another one with trans for 800. If I was going to drop it into my rx7, I could buy the install kit for about 500. The 5.3's are stupid cheap and stupid easy to make power on. Local guy has a bone stock 140k 5.3 with a carb conversion and a cam ($250), after 13 dyno runs, he's at 460hp at the wheels. Figure +20hp if it was still on EFI. |

Yeah, I find that hard to believe. Those things only make ~300hp at the crank stock.

Quote: 10:1 factory compression+huge cam+a lot of dyno time=numbers. Keep in mind that the carb conversion uses an intake that's damn near a tunnel ram.
Yeah, but carbs work by black magic and sorcery. Is it running E85, or something?

So, been busy with work/travel. Finally found time to finish up the IC set up, just in time for the snow LOL. It came out even better than expected. The intercooler although universal, basically bolted right up using the OE bumper supports! Size and spacing were absolutely perfect. I used scrap piped for the hot and cold side. Waiting on the BOV, but besides that, dump tubes, and better clamps-we are injectors away from glory pulls. I used a radiator I had laying around I picked form the junkyard out of a Audi 200 turbo that looked new(er) and a set of cooling fans from the same junk yard run. The rad is 1/2 the thickness of the Hinson that came with the car, but it has done well thus far. I sold the Hinson for $400, so considering the cost of the IC, I actually profited $200 by installing the IC. Showing was done with scraps and aluminum duct foil tape. |

Well she officially has her sea legs. Put another 100 or so mile son it the last nice week we had up here-clutch is a pain in the ass but everything works well now. Hood is on with the new IC set up. I picked up injectors and a 4 bar map for dirt. Working on mult-used 255 set up this weekend if time permits. Then, off to the dyno for some boosted baseline runs. |
