Merg collectors

[Ian Hill]

i just ordered a set from performance welding, i'll report when i get them. Mark asked me every detail of the cam card, horse power info, mph info and then told he had to put the collector together based on the info. it is nice to know that as i am running an ihra crate motor class (not very common), and he has to put something together for the combo and not just go to the shelf and pick one that is close.

First of, i'd just like to say i got a set of mark's performance welding stainless merg collectors recently and the workmanship was excellent. Also he was the only one out of three places i contacted that required my full cam specs - et and mph to put a set together for me, the other two said " they had something in stock that would work". Thank you for that Mark.

Secondly i have to add that i purchased a set of Schoenfeld stepped headers right out of their catologe and during testing (dyno) on a IHRA D/CM fast burn motor these headers out performed two different custom made headers by 17 and 11 horsepower. I order a second set of the same headers without the collectors and added the pref. welding merg's. We dyno'd my engine (ihra crate 350ci/340hp) yesterday and after tuning with the schoenfeld headers/ collector combo it made 455hp with over 400 ft/lbs carried from 3973rpm to 5554rpm. We changed to the schoenfeld/ perf. welding collector combo and after tuning added 2 jets sizes to the rear, took one degree off the timing and hit 474 horse carrying over 400 ft/ lbs from 4113rpm to 5944rpm and this was all on sunoco 94 octane pump gas. changing to 104 race fuel made gains to 478 horse and carried the 400 lbs to 6300 rpm without any jet changes. oh ya, it maxed out at 444ft/lbs on 94oct and 455ft/lbs on the good fuel.

so i'll take this time to thank Schoenfeld Headers, Performance Welding and Fiorravanti Custom Engine for all your help, and you guys for answering my questions.

Thanks

That's awesome Ian, you gotta love it when it works out like that. Mark's collectors do work and here is proof! Good luck this year! Shawn

Ian, all we need now is your social insurance number, pin number for your debit card, and all your credit card numbers with the exiration date and last 3 digets on the back of the card and we will know everything. Hahahaha.Sounds like some pretty impressive numbers. You got 40 more hp than me thats for sure.

theres alway one...oh wait, maybe its the same one over and over again. Simple, i asked quesions and got alot of good advise but no info to back up the replies to my original merg collector question. i did my homework, and am not afraid to fill in the gaps that the others failed to add. Marks collectors were built for the engine and they worked. hopefully they will move my heavy car to some half descent times.

You'll realize what im talking about when you have a "heads up" run. Its good to pay credit and show appriciation but thats over beers and bench racing. Speak softly and carry a big stick. This isn't bracket racing anymore.
