Subject: Re: exhaust systems ..... by jonszr1 on 2010/10/29 13:30:13 so did you finally get a chance to get that pretty el camino running?the 90 with the old flowmaster cat back made 409.9 rwhp and 373.66 tqmax rpms 6800 on the hp and max tq rpms5400 at 2400 rpms tq is335 on the 92with the original corsa exhaustit made 393.2rwhp @6700rpms and361.9 rwqtq@5200rpms .300 wrtq@2500 rpms . i need to go to a dyno and retest them both with the current exhaust. but i think each of their hp levels have gone up 15 aprox buy the improvement in et and mph . the 90 went 116.70 with the flow master and with the dr gas , spin tech setup went 119.85 the 92 went 116.20 and with the current set up went 117.90mile an hr. what size x pipe do you think i out to try 21/2 in or 3 in then back into the 23/4 in pipe . the narrow xpipes from summit arent very expensive maybe i will get both to see what the power and sound levels are .being an old fella (58)i kinda would like the quietest exhaust i can get without loosing too much power . the 3 in dyno max super turbos flow 411 cfm each. i think the real hot setup would be to have that vacume operated valve on one of the tips like the new vets have . may have to see if i can find someone thats figured it out . the new b and b exhaust for the zr1 has that feature.the spin tech is a little drone at 2200 rpm cruize and pretty loud when you floor it . make the car sound a little like a ferarri so others say. opps sorry dont know how to spell italian |
