    Well, we just finished testing the new B&M LS1 Holeshot converter on our B&M Converter Dyno. The specs are 10" diameter, 2400 stall (approx.), and a 2.0/2.1 STR. This should be a nice converter. On the converter dyno it flashed up to 3000 rpms on our 600hp dyno engine. With 230 input TQ, the converter put out (as I witnessed) 481 TQ ... about 2.1 STR. We are testing it out on my SS to see what it really will come out as, I believe it will be a 3000, just called a 2400 for marketing reasons. Much like PI does with theirs. Either way, I'll keep the online community posted. The feedback is always greatly appreciated and I will take it in to consideration. We will be testing out this weekend at LACR and CA Dragway. Our baseline times from LACR with the SS were:

    60' = 2.10
    1/8 ET = 8.94
    1/8 MPH = 81
    1/4 ET = 13.76
    1/4 MPH = 101
    DA = 4280'

    Mods:
    Factory Stock, except as follows
    Hooker LTs & ORY
    M/T ET Streets (26x10.5x16)
    ET Streets were used to minimize tire spin for more consistent times

    After this, I am going to have our converter guy make me a Holeshot 3000 and see what the difference is. The 2400 Holeshot converter can be seen at B&M's SEMA booth.

    BTW: This converter will work on 4.8, 5.3, 5.7, 6.0 trucks with 4L60E transmissions. I may even be able to try it out on my Sierra.

    What kind of vehicle is it you are going to test it on? It would be interesting to see it go head to head with other coverters such as Midwest, Vigilante, TCI and others. I just installed the Midwest 2800 stall converter and am trying to get used to the new feel of this $299 converter.

    Wow, that a really low priced converter! I am going to test it on my 2001 Camaro SS, hoping I can also test it on my 1999 GMC Sierra extra cab. Testing with other converters would be a nice option, I'll see what they say. They will have to be around the same specs, though. I appreciate the input, thanks!
