1. Are you actually try to correct me and make an arrangement in favor of the J85 by stating that it's fuel consumption is even worse than the figures I gave?
You do understand that 1.24lb of fuel per lbf per hour is more than 0.96lb per lbf/hr.
Are you trying to make my argument for me or do you not understand fuel consumption?
Less fuel better! Not more!

2.My argument was about moving on to the J79 as appose the J85 & not about any other engine! Or Iran's technological capabilities and in fact I clearly state that the J85 is below Iran capabilities and that's why we should move on! So what exactly does the Jahesh 700 have to do with anything. It's an Iranian version of a completely different engine and if anything it proves my point! It's time to move on!
3. Thrust per weight! really?
1st off the vast amount of thrust and air flow you achieve is far more useful on a military aircraft and that negates any negative impact of a heavier engine with higher thrust to weight ratio. And if you want prof just compare the military capabilities of the F-5 vs F-4! It's not even a contest! In terms of thrust to weight a micro jet engine could have a better thrust to weight ratio that doesn't make it a suitable engine for a fighter jet!
These are fighter jet engines not cruise missiles or jet powered gliders!
Also in terms of thrust to weight I clearly mentioned that the J79 are big bulky engines that leave a lot of room for upgrade and weight reduction and that makes it far more suited for upgrades then J85
So for R&D and working on improvements the J79 or better yet the Al-21 are far more suited for the task.
As for the Jahesh-700 yes the Jahesh 700 is a leap in engine designs for Iran and it would make a great engine for UAV's and light trainers or maybe even composite tech demonstrators like the Q313 but it's no fighter engine.
The fact that Iran's developed single crystal turbines is clear prof that Iran needs to move on past the J85 & tiny fighter jet engines in general
And by move on I mean you either design your own turbofan, you copy someone else's (Preferably AL-31) or you grab a viable turbojet and improve on it using modern tech you already have
Iran is NOT a country that going to be producing fighter jet engines at a rate greater than 1 per week be they Al-31's or J85's nor is Iran a country that will ever be producing fighter jets at a rate any faster than 1 per month be they Kowsas or Su-35's at least not in the next 2 decades so I'd much rather go with bigger engines and bigger fighter
Plus with UCAV's blooming force multiplication is key when acquiring new fighters so purchasing or building tiny little fighters with limited capabilities and range is nothing but a waist of money!
